Microsoft 365 Retention Policy or Exchange (Legacy) Policy in Exchange Online for In-Place Archiving

Hi,

 

Just a doubt, im trying to implement for automation of moving primary inbox to In-place Archive mailbox,

should i use the retention tags/ policy under Exchange(Legacy) in DLM on Microsoft Purview Compliance?

 

Or would the newer Microsoft 365 Retention Policy/Label be able to do this automation too?

 

Thanks!

    Take the Exchange (Legacy) retention tags/policy. Keep in mind if mailboxes were imported in M365 they are under retentionhold & you have to disable it via powershell. Otherwise the mails are not moving automatically into EXO-Archive.
    You can check it with:
    Get-Mailbox | Select DisplayName,RetentionHoldEnabled,ElcProcessingDisabled
    -> the two parameters need to be $false

      Thanks for the reply!

      will the Exchange (legacy) retention tags/policy clashes with the newer M365 retention policy if both policies are active in EXO?

        edmundcheah1992 not tested yet, but i think so. Use the Exchange (legacy) policy to move the mails to archive. Use the M365 retention policy to retent mails or data.
