Exchange Server Emergency Mitigation
------------------------------------
After Exchange 2019 CU11 admin can enable or disable sending the optional data to the Office Config Service (OCS) on the Exchange server
Set-ExchangeServer -Identity <ServerName> -DataCollectionEnabled $false
OR
Set-ExchangeServer -Identity <ServerName> -DataCollectionEnabled $true
Verify that an Exchange server has connectivity to the OCS using the Test-MitigationServiceConnectivity.ps1 script
EM Service checks the OCS for migigations every 1 Hour
All applicable mitigations are enabled by default
An admin can enable and disable mitigations at an organizational level or at the Exchange server level
Set-OrganizationConfig -MitigationsEnabled $false
OR
Set-ExchangeServer -Identity <ServerName> -MitigationsEnabled $false
To view Applied and Blocked Mitigations
Get-ExchangeServer -Identity <ServerName> | fl name, MitigationsApplied, MitigationsBlocked
A detailed list of available mitigations can also be viewed using the Get-Mitigations.ps1 script
.\Get-Mitigation.ps1 -Identity <Server> -ExportCSV C:\temp\CSVReport.csv
------------------------------------
Exchange Server Feature Flighting
------------------------------------
After Exchange 2019 CU15, Feature Flighting, by default assigns all Exchange Servers to RingLevel 1, this Ring will receive new features as soon as Microsoft has confirmed that the features are ready for general availability.
If you don't want Microsoft to automatically enable new features or make changes to your server via Feature Flighting, you must assign your Exchange servers to Ring 2, in this Ring Flighted features are shipped in a disabled state and must be manually enabled by the administrator.
The following example assigns a server to Ring 2
Set-ExchangeServer -Identity <ServerName> -RingLevel 2
Validate the assignments of Rings on all Exchange Servers in ORG
Get-ExchangeServer | Format-List Identity,RingLevel
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To verify the server is not in maintenance mode, run
Get-ServerComponentState <ServerName> | Format-Table Component,State -Autosize
Note: If you're installing an Exchange update, and the update process fails, it can leave some server components in an inactive state, which will be displayed in the output of the above Get-ServerComponentState cmdlet. To resolve this, run following commands
Set-ServerComponentState <ServerName> -Component ServerWideOffline -State Active -Requester Functional
Set-ServerComponentState <ServerName> -Component Monitoring -State Active -Requester Functional
Set-ServerComponentState <ServerName> -Component RecoveryActionsEnabled -State Active -Requester Functional
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you're installing an Exchange update, and the update process fails, it can leave some server services in disabled state, to resolve this
Check the status of Exchange Services
Get-Service -DisplayName "Microsoft exchange*" | ft DisplayName,Starttype ,Status
If the StartType value for Microsoft Exchange services is Disabled, run the following command in Windows PowerShell to restore the StartType
cd "C:\Program Files\Microsoft\Exchange Server\V15\Bin"
Add-PSSnapin -Name Microsoft.Exchange.Management.PowerShell.Setup -ErrorAction SilentlyContinue
.\ServiceControl.ps1 AfterPatch
Make sure that the status of Microsoft Exchange services display Automatic StartMode
Get-Service -DisplayName "Microsoft exchange*" | ft DisplayName,Starttype ,Status
