    Hi Robert,

    SO how does the Hybrid server work then when migrating to Office 365?  Do you create the hybrid server onsite and then connect your Office 365 Remote move to this hybrid server?

    Thanks

    Martin

    Hi Martin,

    Sorry for the delay.

    Yes, I have received your information.

    To further troubleshoot the issue, can you please confirm whether you have configured any load balancer in your on-premises server? If yes, please temporarily bypass it and do the migration again to test the issue.

    Regards,

    Robert

    Hi Martin,

    I’d like to confirm some information to better understand the issue:

    1. What migration did you perform, IMAP, staged, Cutover or hybrid migration?
    2. Connect PowerShell to Exchange Online: https://technet.microsoft.com/library/jj984289(v=exchg.160).aspx 
    3. Run the following commands:

    Get-MigrationBatch | fl

    Get-MigrationStatistics | fl

    Get-MigrationUserStatistics -Identity user@domainom -IncludeReport | FL

    Note: user@domainom is the problematic user.

    To protect your privacy, I have sent a private message to request the PowerShell output. Please use this link to access the private message:
