During network upload, we get back the error MRSRemoteTransientError. Detail: X-Psws-ErrorCode: 841101 X-Psws Exception: Microsoft.Exchange.Net.CommunicationErrorTransientException X-Psws-Warning: When an item can't be read from the source database or it can't be written to the destination database The error occurs if you specify the UPN or GUID as the target. Via Powershell I don't see any output at Get-MailboxImportRequest. The error occurs with all PST files or with all mailboxes.

    Same Problem here.

    I had a carve in yesterday in which 3 out of 7 .pst failed with the same error.
    one out of that 3 worked after 4 retrys, the other two i manually moved from pst to mailbox now.

    Please Microsoft, take care of the Problem.

    Exactly the same here ,

    had a scenario where cutover migration started erroring and lost its sync,

    sadly MS support was unable to help me at all.

    Decided to cancel the migration job and get missing few weeks of email via PST export and import instead . Worked fine the 1st round .. (9th July 2022)

    Now at migration weekend to go live in the morning and I have about 100mailboxes missing couple weeks of email.

    My import batch had 180 PSTs/Users, and only about 80 imported, the rest keeps failing with this same error no matter what I try :\

    MS Please fix it, see this is happening "globally"
