    Hello,

    I'm facing an issue, users migrated to Office 365, that had on prem message limit of 9 MB, still have this limit applied.

    From powershell connected to O365, this mailbox's message limit shows 35 MB.

    From powershell connected to Exchange on prem, (get-remoteMailbox), the same message limit is showing 9 MB, and this is the one applied.

    I cannot change it with the "set-remoteMailbox". Any advice please?

    Thank you.


    Chris

    If you look in ADUC with the advanced view or adsiedit for that account, what is set for the attribute "delivContentLength" ? If set, clear that.

    Hi,

    Agree with Andy, we can also refer to the article which detailedly introduced about The Story of Message Size Limits and Remote Mailboxes

    MaxSendSize in Exchange is the equivalent of submissionContLength in AD

    MaxReceiveSize in Exchange is the equivalent of delivContLength in AD
