    It stops processing the mailbox, in other words no items from user-accessible folders will be automatically deleted or moved to the Online archive. The Recoverable items subtree is unaffected by this, and thus deleted items will follow the "regular" lifecycle workflow.

    For additional details consult the official documentation here:

    Hello @Kael Yao-MSFT @Vasil Michev

    In my organization, there are two policies applied to our mailbox: the MRM Policy, as mentioned by Kael, and a second Retention Policy under Data Lifecycle Management > Microsoft 365.

    However, I'm unsure which policy is applied first. Any ideas, please? if this last policy was applied first i think i can

    Set-Mailbox -RetentionHoldEnabled $false , without any impact for the users once i imported thye pst file with items out of the age of the retention policy which here 5 years **!

    Many thanks**
