You are interested in OneDrive and OneDrive for Business? You want to know how you can integrate the OneDrive technology into your IT infrastructure securely?
Here is the list of OneDrive related sessions at Microsoft Ignite 2017
See you at Microsoft Ignite!
Starting September 11th 2017 Microsoft Teams supports guest access for external users.
Guest access for Microsoft Teams uses a separate guest license type that must be activated in the services & add-ons section of the Office 365 Admin portal.
Office 365 Admin portal notification:
When we make this change, the ‘Pick the license you want to configure’ setting in ‘Settings > Services and Add-ins > Microsoft Teams’, will now have an option for ‘Guest’ with a default value of “off” for the ‘Turn Microsoft Teams on or off for your entire organization’ setting.
When you've not activated guest licenses, external user receive an odd error when trying to access your shared team.
Enjoy Office 365!
It's going to be an interesting week next week at Microsoft Ignite in Orlando, FL.
There will be a lot announcements about Microsoft Technologies to come.
The conference is the best opportunity to learn about new technologies and to extend your IT professional network.
If you want to talk about OneDrive for Business, Exchange On-Premises and Exchange Online solutions, or how you can move to cloud service contact me by email or Twitter to schedule a meeting.
See you in Orlando.
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.
Add-PsSnapin Microsoft.Exchange.Management.PowerShell.Setup New-PerfCounters -DefinitionFileName "$exinstall\setup\perf\WorkerTaskFrameworkPerfCounters.xml”
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
Restart-Service MSExchangeIS Restart-Service MSExchangeSA
I haven’t noticed any issues in production environments so far. If you encounter any issues in your environment, feel free to leave a comment.

Public folders are one solution to provide a team collaboration tool for companies. Legacy public folders utilized a proprietary multi master replication mechanism which was not planned to handle todays data volumes. Therefore, Exchange 2013 introduced modern public folders which utilize the robust DAG replication functionality. Due to the technology change between legacy public folders and modern public folders a migration is required.
You can migrate legacy public folders hosted on Exchange 2007 or Exchange 2010 to modern public folders hosted on Exchange 2013. Or you can migrate legacy public folders hosted on Exchange 2010 to modern public folders hosted on Exchange 2016. If a cloud migration is a viable option for your company, you are able to migrate legacy public folders hosted on Exchange 2007 or Exchange 2010 to modern public folders hosted in Exchange Online.
The requirements for legacy Exchange Servers are:
Since Exchange Server 2013 RTM the public folder migration scripts and the migration guidance have quite often been updated. The information provided at TechNet is very detailed for each migration option and there is no need to repeat each step in this blog post. Please see the link section for all hyperlinks.
Preparing a legacy public folder migration is pretty straight forward. The main issue companies are facing is the required downtime for finalizing the public folder migration batch. The required downtime cannot be determined exactly (not as exactly as requested by upper management). Which means that you have to plan for a scheduled maintenance during off hours. In the past a single migration request has been used to migrate legacy public folders. The new batch approach migrates public folder content using multiple requests within a single batch.
The Create-PublicFolderMailboxesForMigration.ps1 script uses the parameter EstimatedNumberOfConcurrentUsers to determine the overall number of public folder mailboxes serving the hierarchy. The TechNet articles explain this parameter as follows:
The estimated number of simultaneous user connections browsing a public folder hierarchy is usually less than the total number of users in an organization.
Exchange Server 2013 and Exchange Server 2016 currently support 2.000 concurrent connections to a single mailbox. This limit (2.000) is used by the Create-PublicFolderMailboxesForMigration.ps1 in conjunction with EstimatedNumberOfConcurrentUsers to determine the number of public folder mailboxes required to serve the public folder hierarchy. The current version of the script uses a coded limit of max 100 public folder mailboxes. This means that you can only serve 100 x 2.000 = 200.000 concurrent users accessing the public folder hierarchy.
Finalizing the migration request and setting the PublicFolderMigrationComplete attribute requires the legacy public folder information store to be restarted. Otherwise the configuration change will not be picked up the information store in timely fashion. Remember to restart the information store service on all legacy public folder servers.
If your current public folder infrastructure is based on Exchange 2007 and you want to get rid of that Exchange version, you might think of replicating all content to Exchange 2010. This is not the best approach. Due to known content conversion issues you might encounter data loss when replicating public folder content between Exchange 2007 and Exchange 2010.
The recommended approach is to migrate Exchange 2007 legacy public folders to Exchange 2013 modern public folders directly.
A recommended reading on legacy public folder migration from Exchange 2010 to Exchange 2016 is Butch Waller’s blog post “Migration to Modern Public Folders – Notes from the Field”
The PowerShell script referenced in that blog post does not work with Exchange 2007. You can use my PowerShell script which utilizes UTF8 encoding and runs with Exchange 2007 and Exchange 2010: https://gallery.technet.microsoft.com/Exchange-2010-Public-315ea9aa
