Symptoms
In Microsoft Exchange Server 2019 or Exchange Server 2016, consider the following scenario:
-
For any user, change the ECPEnabled parameter value to $false by using the following Set-CASMailbox cmdlet:
Set-CASMailbox NoEcp01 -ECPEnabled $false
-
You use the following Get-CASMailbox cmdlet to view the change that you made:
Get-CASMailbox -Filter ECPEnabled -eq $false'
In this situation, the output should be:
Name ECPEnabled
---- ----------
NoECP01 False
However, the Get-CASMailbox cmdlet doesn't return any results even if the ECPEnabled parameter is set to $false.
Cause
This issue occurs because a wrong Lightweight Directory Access Protocol (LDAP) filter is used when you run the Get-CASMailbox cmdlet for the ECPEnabled parameter.
Resolution
To fix this issue, install one of the following updates:
For Exchange Server 2019, install the Cumulative Update 7 for Exchange Server 2019 or a later cumulative update for Exchange Server 2019.
For Exchange Server 2016, install the Cumulative Update 18 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.
