It might happen that a mobile device running an Android operating system is not being redirected properly by the on-premises AutoDiscover service, when the mailbox has been migrated to Office 365.
If your device is not redirected, the device prefix is not recognized by Exchange Server and therefore not being redirected properly. The new device redirect feature for Android devices was introduced in Exchange Server 2010 SP3 RU9, Exchange Server 2013 CU8, and Exchange Server 2016.
The following device prefixes are known to Exchange by default:
If the device prefix of your device is not part of the default list, you can add the prefix to the AutoDiscover web.config file.
Add the device prefix to the MobileSyncRedirectBypassClientPrefixes key in the appSettings node.
<appSettings> <add key="LiveIdBasicAuthModule.AllowLiveIDOnlyAuth" value="true" /> <add key="LiveIdBasicAuthModule.ApplicationName" value="Microsoft.Exchange.Autodiscover" /> <add key="LiveIdBasicAuthModule.RecoverableErrorStatus" value="456" /> <add key="LiveIdBasicAuthModule.PasswordExpiredErrorStatus" value="457" /> <add key="ActiveManagerCacheExpirationIntervalSecs" value="5" /> <add key="ProxyRequestTimeOutInMilliSeconds" value="30000" /> <add key="LiveIdNegotiateAuxiliaryModule.AllowLiveIDOnlyAuth" value="true" /> <add key="TrustedClientsForInstanceBasedPerfCounters" value="bes" /> <add key="InstanceBasedPerfCounterTimeWindowInterval" value="900000" /> <add key="MobileSyncRedirectBypassEnabled" value="true" /> <add key="MobileSyncRedirectBypassClientPrefixes" value="Acer,ADR9,Ally,Amazon,Android,ASUS,EasClient,FUJITSU,HTC,HUAWEI,LG,LS,Moto,Mozilla,NEC,Nokia,Palm,PANASONIC,PANTECH,Remoba,Samsung,SEMC,SHARP,SONY-,TOSHIBA,Vortex,VS,ZTE" /> </appSettings>

You might have the requirement to authenticate mobile devices and authorize user access to on-premises Exchange Server mailboxes using a multi-vendor strategy. This blog post focuses on the configuration of a Kemp LoadMaster located in an internal network segment. The Kemp LoadMaster ESP functionality is used to allow ActiveSync connections for members of a dedicated security group only.
This results in the following authentication and authorization endpoints:
The following diagram shows a simplified overview for mobile devices connecting to an on-premises Exchange Server. The perimeter and internal network segments are omitted for simplification reasons.
The following screenshots illustrate a working setup for a virtual service load balancing mobile device connections from MobileIron Sentry to Exchange Server. It's assumed that you've already configured the following:
The SSL Traffic is offloaded and re-encrypted as we need to authenticate the user with ESP. Ensure to select a Cipher Set that does not provide any weak or unsecure cipher suites. In this example I've selected the predefined set BestPractices.
Enable ESP to activate the ESP configuration section. The settings are as follows:
In the Real Servers section you add all member servers of your Exchange Server DAG. Ensure to use the HTTPS protocol the health checks and ensure to query the /Microsoft-Server-ActiveSync/healthcheck.htm document.
Using this configuration you've added your Kemp LoadMaster as an additional authentication endpoint to secure mobile device access to Exchange Server mailboxes.
Enjoy!
Migrating legacy public folders (Exchange Server 2010 or older) to modern public folders (Exchange 2013 or newer / Office 365) requires a cleanup of public folders.
There are quite a lot of blog posts and tutorials available describing the general process of migrating legacy public folders to modern public folders.
First you have to identify all public folders having a backslash "\" as part of the public folder name.
Get-PublicFolderDatabase | ForEach {Get-PublicFolderStatistics -Server $_.Server | Where {$_.Name -like "*\*"}}
Just rename those public folders to a name without a backslash.
Another issue might prevent a successful public folder migration: Access Controll Lists (ACL)
This will be the case in public folder hierarchies that go back to the early days of Exchange and have never cleaned up properly during past Exchange migrations.
The cleanup any orphaned Active Directory accounts, run the following PowerShell script.
Get-PublicFolder "\" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | ?{$_.User -like "NT User:S-1-*"} | %{Remove-PublicFolderClientPermission -Identity $_.Identity -User $_.User -Access $_.AccessRights -Confirm:$false}
To cleanup just a single public folder, run the following PowerShell script.
Get-PublicFolder "\My Folder" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | ?{$_.User -like "NT User:S-1-*"} | %{Remove-PublicFolderClientPermission -Identity $_.Identity -User $_.User -Access $_.AccessRights -Confirm:$false}
It should be noted that most of the tutorials have been written using an Exchange Server lab environment with just a few legacy public folders. Therefore, some readers tend to beleive that you only need one modern public folder mailbox. That is not true. In a large legacy public folder infrastructure you will end up with a multiple public folder mailboxes. And the number of mailboxes required to serve the public folder hierarchy.
A larger public folder migration batch using 66 public folder mailboxes looks like this:
Get-MigrationUser -BatchID PFMigration | Get-MigrationUserStatistics | ft -AutoSize Identity Batch Status Items Synced Items Skipped -------- ----- ------ ------------ ------------- PFMailbox1 PFMigration Synced 91993 16 PFMailbox2 PFMigration Synced 103239 0 PFMailbox46 PFMigration Synced 35034 0 PFMailbox56 PFMigration Synced 22554 0 PFMailbox57 PFMigration Synced 20740 0 PFMailbox58 PFMigration Synced 20122 0 PFMailbox59 PFMigration Synced 7209 0 PFMailbox60 PFMigration Synced 104727 0 PFMailbox61 PFMigration Synced 23278 0 PFMailbox62 PFMigration Synced 9760 0 PFMailbox63 PFMigration Synced 9277 0 PFMailbox65 PFMigration Synced 5870 0 PFMailbox64 PFMigration Synced 5639 0 PFMailbox66 PFMigration Synced 21261 0 PFMailbox50 PFMigration Synced 27889 0 PFMailbox52 PFMigration Synced 14063 0 PFMailbox47 PFMigration Synced 29476 0 PFMailbox54 PFMigration Synced 24283 0 PFMailbox55 PFMigration Synced 4646 0 PFMailbox51 PFMigration Synced 59943 0 PFMailbox53 PFMigration Synced 30052 0 PFMailbox49 PFMigration Synced 22746 0 PFMailbox48 PFMigration Synced 16941 0 PFMailbox18 PFMigration Synced 34307 0 PFMailbox19 PFMigration Synced 4523 0 PFMailbox11 PFMigration Synced 100409 0 PFMailbox6 PFMigration Synced 116655 0 PFMailbox4 PFMigration Synced 55240 5 PFMailbox12 PFMigration Synced 37790 0 PFMailbox3 PFMigration Synced 113842 2 PFMailbox22 PFMigration Synced 46416 0 PFMailbox23 PFMigration Synced 37387 0 PFMailbox13 PFMigration Synced 231845 1 PFMailbox7 PFMigration Synced 82859 0 PFMailbox20 PFMigration Synced 65818 0 PFMailbox21 PFMigration Synced 32270 0 PFMailbox9 PFMigration Synced 46609 0 PFMailbox14 PFMigration Synced 30637 0 PFMailbox38 PFMigration Synced 246428 1 PFMailbox43 PFMigration Synced 101837 0 PFMailbox45 PFMigration Synced 157571 0 PFMailbox44 PFMigration Synced 61763 0 PFMailbox40 PFMigration Synced 70637 1 PFMailbox41 PFMigration Synced 143042 0 PFMailbox42 PFMigration Synced 81254 0 PFMailbox39 PFMigration Synced 68876 2 PFMailbox15 PFMigration Synced 58221 0 PFMailbox27 PFMigration Synced 28065 0 PFMailbox24 PFMigration Synced 31869 1 PFMailbox5 PFMigration Synced 64125 0 PFMailbox30 PFMigration Synced 72938 1 PFMailbox33 PFMigration Synced 32545 1 PFMailbox31 PFMigration Synced 93782 0 PFMailbox32 PFMigration Synced 28743 0 PFMailbox25 PFMigration Synced 100794 0 PFMailbox26 PFMigration Synced 35412 0 PFMailbox28 PFMigration Synced 27003 0 PFMailbox29 PFMigration Synced 80510 0 PFMailbox17 PFMigration Synced 97952 1 PFMailbox8 PFMigration Synced 18601 0 PFMailbox34 PFMigration Synced 87150 0 PFMailbox35 PFMigration Synced 31531 0 PFMailbox36 PFMigration Synced 37979 0 PFMailbox37 PFMigration Synced 95770 0 PFMailbox10 PFMigration Synced 14193 0 PFMailbox16 PFMigration Synced 64323 1

Mail flow from on-premises devices and applications to Exchange Online is a tricky topic. The documentation allows for different solutions.
Recently a client ran into a situation where an on-premises application was not able to deliver messages to a configured inbound connector in the Exchange Online tenant. The connector was configured for remote IP address selection.
Exchange Online responded to each connection attempt with the following error message:
There weren't any changes on the on-premises configuration and the setup was in use for multiple months without any issues.
It took some time to identify the solution, but in the end, the solution was easy.
Disabling and re-enabling solved the issue.
Enjoy Exchange Online.
There are three different ways to configure new Exchange user mailboxes after these have been created.
The Exchange cmdlet extension is controlled by a scripting agent configuration file and a organizational setting to enable/disable the scripting agent.
A scripting agent configuration file sample (ScriptingAgentConfig.xml.sample) is located in
The sample needs to be renamed to ScriptingAgentConfig.xml, to be picked up the PowerShell engine.
As always, a slight reminder: Test any modification in a test environment first, before you use the extension in a production environment.
After succesfull testing and deployment, you need to enable the scripting agent using
Enable-CmdletExtensionAgent "Scripting Agent"
Even thought that you can extend mostly any Exchange cmdlet, this example covers the extension of the New-Mailbox and Enable-Mailbox cmdlets in a multi domain and multi AD site environment.
This extension disables the following CAS mailbox settings, after a new mailbox has been created:
What does the example do?
<?xml version="1.0" encoding="utf-8" ?> <Configuration version="1.0"> <Feature Name="MailboxProvisioning" Cmdlets="New-Mailbox,Enable-Mailbox"> <ApiCall Name="OnComplete"> If ($succeeded) { if (!($provisioningHandler.UserSpecifiedParameters.Archive -eq $true)) { # delay execution for 10 seconds, adjust as needed Start-Sleep -s 10 # validate parameters to use a not null parameter if ($provisioningHandler.UserSpecifiedParameters["Identity"] -ne $null) { $user = $provisioningHandler.UserSpecifiedParameters["Identity"].ToString() } elseif ($provisioningHandler.UserSpecifiedParameters["Name"] -ne $null) { $user = $provisioningHandler.UserSpecifiedParameters["Name"].ToString() } else { $user = $provisioningHandler.UserSpecifiedParameters["Alias"].ToString() } # view entire forest in a multi domain environment Set-AdServerSettings -ViewEntireForest:$true # fetch domain controllers in AD site} $server = Get-ExchangeServer $env:computername $DCs = Get-DomainController | ?{$_.adsite -eq $server.site} $CasMailbox = $null foreach($d in $DCs) { while($CasMailbox -eq $null) { # find a valid domain controller having the updated user object $CasMailbox = Get-CASMailbox $user -DomainController $d.dnshostname -ErrorAction SilentlyContinue # fetch DCs FQDN $WriteDC = $d.DnsHostName break } } try { # set CAS features as needed Set-CasMailbox $user -ActiveSyncEnabled:$false -ImapEnabled:$false -PopEnabled:$false -MapiHttpEnabled:$false -DomainController $WriteDC -ErrorAction SilentlyContinue } catch {} } } </ApiCall> </Feature> </Configuration>
After adding the PowerShell code to the ScriptingAgentConfig.xml file, the file needs to be distributed across all Exchange servers. For distribution of the scripting agent configuration file I personally recommend Paul Cunningham's PowerShell script.
Be aware of the fact, that the scripting agent Xml is being validated using a strict schema validation. The scripting agent Xml is case sensitive, as noted here.
