During HEX mailbox migration to a higher Exchange version the following cmdlet is executed, which actually makes no changes to the mailbox:

Set-CASMailbox -Identity "CN=client1,OU=S001000012,OU=Provider,OU=Hosting,DC=hosting,DC=local" -DomainController

In addition, the below cmdlet is executed 3 times, instead of 1:

Set-Mailbox -DomainController -Identity "CN=client1,OU=S001000012,OU=Provider,OU=Hosting,DC=hosting,DC=local" -ProhibitSendReceiveQuota Unlimited 

These unnecessary cmdlet calls can affect the migration speed.


The described behavior will be improved in the scope of the following issues:

  • POA-116619: Set-CASMailbox called with no need
  • POA-116627: Set-Mailbox called 3 times during moving mailbox


Please contact your Technical Account Manager in order to track the current status of the issue.
