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.

    Hello,

    We are having the same issue it seems, at least since 7/19. We are unable to successfully import ANY PST files in Compliance Center > Data Lifecycle Management > Import. Import stays at 0% a long time and then fails with "Completed with errors" status message. However, upon inspection of job details, it shows Status "Failed" with 0 items imported.

    Error log contains the following information:

    Failed,MRSRemoteTransientError,0,0,0,Microsoft.Exchange.Net.CommunicationErrorTransientException
    The call to 'net.tcp://XXXXXXXXXXXXX.XXXXXXX.prod.outlook.com/Microsoft.Exchange.MailboxReplicationService XXXXXXXXXXXXX.XXXXXXX.prod.outlook.com (15.20.5482.6 ServerCaps:3FFFFFFF
    ProxyCaps:03FFFFFFFFFFFFC7DD2DFDBF5FFFFFCB07EFFF,MailboxCaps:legacyCaps:3FFFFFFF)' failed. Error details: Could not load file or assembly 'Azure.Core

    Status: ProtocolError
    Status code: InternalServerError (500)
    X-Psws-ErrorCode: 841101
    X-Psws-Exception: Microsoft.Exchange.Net.CommunicationErrorTransientException

    What's very interesting is that if I run the command "Get-MailboxImportRequestStatistics ******@domain.com" to check on the status of the Import, it doesn't even register the Import Request at all.

    The result is:

    Write-ErrorMessage : Microsoft.Exchange.Configuration.Tasks.ManagementObjectNotFoundException No such request exists in the specified index.

    And if i run "Get-MailboxImportRequest" to show a list of requested imports, there is NOTHING in the list after 7/11.

    So it's as if these Import requests are just not registering at all.

    I have tried using different admin accounts, different PST files, and different mailboxes - using both UPN and GUID. Everything fails. I have a support case open with Microsoft on this, but so far they have not been able to figure it out. I think this is a wider issue than they know, but hasn't been well reported yet.

    Thank you,

    Dave

    I want to import a PST file into a mailbox through the Compliance Center. It is not a hybrid Exchange environment. We only use Exchange Online. I have the same error in another tenant. Is there a general problem?
