Once upon a time at an Exchange Conference near you, a member of the Exchange Product Group (PG) announced that the very last Exchange Server will go away when having an active Exchange hybrid setup.
This was a hot topic for discussions at the Microsoft Exchange Conferences (MEC, @IamMEC) in 2012 and 2014, already. Since then the Exchange PG came up with a number of reasons why this is not possible. The question on when we will finally be able to remove the very last Exchange Server from the on-premises Exchange organization was asked every year at the Ignite Conference.
Currently, the supported scenario for hybrid configurations between your on-premises Exchange organization and Exchange Online requires that you keep the last Exchange Server for creating, and managing Exchange related objects, even if those objects are located in Exchange Online.
The following diagram illustrates the current requirements:
In the past, there was communication on certain interim solutions that were supposed to support you in removing the last Exchange Server from your Exchange organization. Such interim solutions were:
At Ignite those solutions even made it into the official session catalog:
All those interim solutions leave your on-premises Exchange organization and the Active Directory configuration in an uncomfortable twilight-zone. It was still something that worked somehow, but you knew it was officially not supported, and the secure and stable operation of the hybrid configuration was at risk.
But wait...
Removing the last Exchange Server is supported! (at least when all components are released)
The new approach for managing your Exchange Online tenancy after migrating your on-premises Exchange organization to Exchange Online does not require an on-premises Exchange Server.
The new mode of operation reduces your on-premises requirements to:
The following diagram illustrates the new modern Exchange Online Management experience:
Simply you remove the requirement to use on-premises Exchange Server to write to your on-premises Active Directory. Instead, Azure AD Connect uses a new synchronization capability to handle the new Exchange Management experience in the AAD Connect MetaVerse. The on-premises AD-connector writes the changes to Active Directory which keeps the Active Directory up-to-date for all other on-premises solutions that require identities to have a proper state.
You execute all Exchange-related actions using the new Exchange Online Management PowerShell module, or, if needed, the new Modern Exchange Admin Center (EAC, which was announced at Ignite 2019.
Before you uninstall the last Exchange Server from your on-premises Exchange organization, ensure that you

Even though not explicitly stated, you should restart the server after installing the Windows feature.
As part of the next AAD Connect synchronization cycle, the magic happens.
Verify that you can edit the Exchange related attributes of synchronized Active Directory objects in Exchange Online or Azure AD before you remove your last Exchange Server.
Whey ready to uninstall the last Exchange Server you must use the following command line parameters to remove the server as intended. Otherwise, you'll leave the Exchange organization in an inchoate state. Ensure that you use an administrative PowerShell session.
./Setup.exe /mode:uninstall /SwitchToMEMA /IAcceptExchangeOnlineLicenseTerms
Normally, you do not have to accept license terms when uninstalling Exchange Server, but in this case, you have to accept the Exchange Online license terms.
Enjoy the modern experience and management options of Exchange Online!

You are not able to list public folders in a co-existence scenario with Exchange Server 2007 and Exchange Server 2010/2013 using the Exchange 2007 EMS or EMC.
When you try to execute Get-PublicFolder you receive the following error:
Get-PublicFolder " There is no existing PublicFolder that matches the following Identity: '\'. Please make sure that you specified the correct PublicFolder Identity and that you have the necessary permissions to view PublicFolder.
This might happen after you have removed the first Exchange 2007 mailbox server, but not the last Exchange 2007 mailbox server.
Exchange Server 2007 uses the Exchange System Attendant to access the public folder store and fails, if the System Attendant discovery in Active Directory does not provide a proper configuration.
KB 2621350 describes the discovery process:
There two annoying things about these steps
The magic System Attendant mailbox has been removed from Exchange 2010. But the System Attendent configuration node does still exist in the Active Directory Configuration Partition for compatibility reasons. The configured attributes of the System Attendent entry vary depending on the version of the installed Exchange Server.
In regards of public folder issue, we need to focus on the following:
To fix the public folder access issue for Exchange Server 2007, set the homeMDB and homeMTA attributes. Set the Exchange System Attendant attributes to appropriate values for your Exchange servers.
Repeat steps 4 to 8 for each Exchange 2013 server in your environment.
Repeat steps 4 to 13 for each Exchange 2010 server in your environment.
Wait for Active Directory replication and retry to access the public folders using Get-PublicFolder in an Exchange Server 2007 Management Shell.
It might be required to restart the Exchange 2007 Information Store and System Attendant service of the Exchange 2007 server in question
Use an administrative PowerShell

This script will generate a report for Exchange 2007/2010 Public Folder Replication. It returns general information, such as total number of public folders, total items in all public folders, total size of all items, the top 20 largest folders, and more. Additionally, it lists each Public Folder and the replication status on each server.
By default, this script will scan the entire Exchange environment in the current domain and all public folders. This can be limited by using the -ComputerName and -FolderPath parameters.
NOTE: This is an updated version of the Mike Walker (blog.mikewalker.me) to support non-ASCII environments.
Generate a public folder generation report for public folder \MYPUBLICFOLDER having replicas on servers MXSRV01, MXSRV02, MXSRV03
Get-PublicFolderReplicationReport.ps1 -ComputerName MXSRV01,MXSRV02,MXSRV03 -FolderPath "\MYPUBLICFOLDER" -Recurse -Subject "Public Folder Environment Report" -AsHTML -To postmaster@varunagroup.de -From postmaster@varunagroup.de -SmtpServer relay.mcsmemail.de -SendEmail
Example report
If you want to simplufy the report generation, create an addtional script: Run-PublicFolderReplicationReport.ps1
param( [string]$publicFolderPath = '' ) # Variables # Custom label for email subject $label = 'Exchange 2007' $recipients = 'pfreports@mcsmemail.de' $sender = 'postmaster@mcsmemail.de' # array of public folder servers to query $publicFolderServers = @('EX2007-01','EX2010-01') # SMTP server to relay mail $smtpServer = 'relay.mcsmemail.de' # Used to trigger a dedicated report for \GrFolder1\Folder1, \GrFolder1\Folder2 $granularRootFolder = @() # @("\Folder01") $subPath = '' # Check for granular folders, Added 2016-01-19 if($granularRootFolder -contains $publicFolderPath) { $subPath = $publicFolderPath $publicFolderPath = '' } # if($publicFolderPath -ne '') { Write-Host "Generating Public Folder reports for $($publicFolderPath)" # Generate report for a single public folder | Change COMPUTERNAME attribute for servers to analyse .\Get-PublicFolderReplicationReport.ps1 -ComputerName $publicFolderServers -FolderPath $publicFolderPath -Recurse -Subject "Public Folder Environment Report [$($publicFolderPath)] [$($label)]" -AsHTML -To $recipients -From $sender -SmtpServer $smtpServer -SendEmail } else { if($subPath -ne '') { $publicFolderPath = $subPath } else { $publicFolderPath = '\' } if($granularRootFolder.Count -ne 0) { Write-Host 'Following root folders will be excluded when using "\":' $($granularRootFolder) } Write-Host "Generating Public Folder reports for all folders in $($publicFolderPath)" $folders = Get-PublicFolder $publicFolderPath -GetChildren # Generate a single report for each folder in root $folderCount = ($folders | Measure-Object).Count $pfCount = 1 foreach($pf in $folders) { # Check, if folder is in list of granular folders if($granularRootFolder -notcontains $pf) { if($pf.ParentPath -eq '\') { $name = "$($pf.ParentPath)$($pf.Name)" } else { $name = "$($pf.ParentPath)\$($pf.Name)" } $activity = 'Generating Stats' $status = "Fetching $($name)" Write-Progress -Activity $activity -Status $status -PercentComplete (($pfCount/$folderCount)*100) .\Get-PublicFolderReplicationReport.ps1 -ComputerName $publicFolderServers -FolderPath $name -Recurse -Subject "Public Folder Environment Report [$($name)] [$($label)]" -AsHTML -To $recipients -From $sender -SmtpServer $smtpServer -SendEmail $pfCount++ } } }
Use the $granularRootFolder array to add root public folders which require a dedicated report for each sub-folder.

This Powershell script has been optimized using the ISESteroids™ add-on. Learn more about ISESteroids™ here.
This script reads Exchange Organization data and creates a single Microsoft Word document. A later version will support exporting to an Html file.
The script requires an Exchange Management Shell for Exchange Server 2016 or newer. Older EMS versions are not tested.
A locally installed version of Word is required, as plain Html export is not available, yet.
The default file name is 'Exchange-Org-Report [TIMESTAMP].docx'.
Most of the script requires only Exchange admin read-only access for the Exchange organization. Querying address list information requires a membership in the RBAC role "Address Lists".
The script queries hardware information from the Exchange server systems and requires local administrator access to the computer systems.
# Example 1 # Create a Word report for the local Exchange Organization using # the default values defined on the parameters section of the PowerShell script. .\Get-ExchangeOrganizationReport.ps1 -ViewEntireForest:$true # Example 2 # Create a Microsoft Word report for the local Exchange Organization with # a verbose output to the current PowerShell session. .\Get-ExchangeOrganizationReport.ps1 -Verbose
The script is based on the ADDS_Inventory.ps1 PowerScript by Carl Webster: https://github.com/CarlWebster/ActiveDirectory
The Exchange Server product used the Extensible Storage Engine (ESE, aka JET Blue) to store data for decades. The story of the JET Blue (in contrast to JET Red which is used for Access database) can be read here (https://en.wikipedia.org/wiki/Microsoft_Jet_Database_Engine). In the acient days of data storage the ESE database was the best choice for storing mostly unstructured data with many dynamic properties.
The Messaging API (MAPI) had been developed in the 1990s to provide programmers with a set of unified interface for easier message exchange. The MAPI documentation at TechNet has been replaced by the current Outlook 2013 MAPI Reference. In todays world it is not easy to find reliable ressource about the original MAPI implementation. The only printed resource is Inside Mapi (Microsoft Programming Series) , ISBN 978-1572313125 , which has been published in 1996.
At Ignite 2015 Ross Smith VI joked about moving the Exchange storage engine to SQL. Back in the day with Exchange 2013 in production and Exchange 2016 coming, this was true. But Ross laid the tracks for the evolution of Exchange.
But it seems that the Exchange Product Team realized that in today's world with heavily standardized communication and less dynamic requirements than in the 1990s the days of JET blue are over. At the same time SQL Server evolved to mature database solution, capable of handling big data. The question was, if it can store SharePoint data, why not Exchange data. After twenty years of Exchange Server using the good ole ESE engine it was time to move on.
The SQL scripts that are used by Exchange to configure SQL are loacted in $exbin\SQL
CREATE TABLE [dbo].[MAPI_PROPERTIES]( [MAPI_PROPERTTY_ID] [int] IDENTITY(1,1) NOT NULL, [MAPI_PROPERTY_NAME] [nchar](127) NOT NULL, [IsWellKnownProperty] [bit] NOT NULL, [MAPI_TYPE_ID] [int] NOT NULL, CONSTRAINT [PK_MAPI_PROPERTIES] PRIMARY KEY CLUSTERED ( [MAPI_PROPERTTY_ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[MAPI_PROPERTIES] WITH CHECK ADD CONSTRAINT [FK_MAPI_PROPERTIES_MAPI_TYPES] FOREIGN KEY([MAPI_TYPE_ID]) REFERENCES [dbo].[MAPI_TYPES] ([MAPI_TYPE_ID]) GO ALTER TABLE [dbo].[MAPI_PROPERTIES] CHECK CONSTRAINT [FK_MAPI_PROPERTIES_MAPI_TYPES] GO
The current Exchange 2016 CU2 Preview supports an undocumented registry key to activate SQL Server support for Exchange. Personally I do not know, if this was supposed to be officially included in a public realease. So maybe the SQL support was made available by error and is already removed from the most current build again.
The famous SqueakyLobster registry key in has been used in Exchange 5.5 to troubleshoot performance issues. The new "Lobster" key is used to activate hidden code in Exchange Server product. The name of the key is LobsterMapiDB.
This key activates support for Exchange modern storage. Without this key you won't be able to move mailboxes from ESE legacy storage to SQL modern storage.
It is assumed that a SQL Server 2014 instance is available. A SQL Server 2014 Express edition is sufficient for testing purposes.
Note: Any changes to configurations or the registry should be validated in a test environment first. Never try this in production right away.
The high level steps required to activate SQL support for Exchange 2016 are:
The detailed steps are:

You might encounter EventId 106 errors on Exchange 2013/2016 servers.
There are some article available on how to fix this issue on servers having a full installationof Exchange Server 2013/2016.
But you might encounter this error on servers having the Exchange 2013/2016 Management Tools installed only as well. In this case the solutions described will not work as expected.
Running the New-PerfCounters cmdlet requires the Microsoft.Exchange.Management.PowerShell.Setup PowerShell snapin. This PowerShell snapin cannot be loaded on servers having the Exchange Management Tools installed.
Add-PsSnapin : The Windows PowerShell snap-in 'Microsoft.Exchange.Management.PowerShell.Setup' is not installed on this computer. At line:1 char:1 + Add-PsSnapin Microsoft.Exchange.Management.PowerShell.Setup + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (Microsoft.Excha...owerShell.Setup:String) [Add-PSSnapin], PSArgumentEx ception + FullyQualifiedErrorId : AddPSSnapInRead,Microsoft.PowerShell.Commands.AddPSSnapinCommand
The required code library is available on servers having the Exchange Management Tools installed. But the library is not added to the registry by default.
Registry of a server running Exchange Management Tools only:
Registry of a fully installed Exchange Server:
Just export the registry key Microsoft.Exchange.Management.PowerShell.Setup from an Exchange Server, fix Exchange file paths (if required) and import the regiytry file on the server having the Exchange Management Tools installed.
Example registry file:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.PowerShell.Setup] "CustomPSSnapInType"="Microsoft.Exchange.Management.PowerShell.SetupPSSnapIn" "ApplicationBase"="D:\\Program Files\\Microsoft\\Exchange Server\\V15\\bin" "AssemblyName"="Microsoft.Exchange.PowerShell.Configuration, Version=15.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" "Description"="Setup Tasks for the Exchange Server" "ModuleName"="D:\\Program Files\\Microsoft\\Exchange Server\\V15\\bin\\Microsoft.Exchange.PowerShell.configuration.dll" "PowerShellVersion"="1.0" "Vendor"="Microsoft" "Version"="15.0.0.0"
After adding the registry key, you can successfully fix the performance counter issue.
