Exchange 2007 - restored (merged) Mailboxes - Problem with items in Outlook RRS feed

  • Question

  • Hey guys,

    last week we had to restore and merge our Exchange Mailbox Database. We had a running Database with data until Oct 14 and merged a recent backup into the User Mailboxes.

    Some mailboxes didn´t have problems, others have from then on doublicated Mails, Calendar Items, Tasks, ... even deleted/renamed folders appear now again WITH email content.

    I don´t understand what happend there and if I can do something.

    Hope someone could help me!

    Regards

  • Hi,

    According your post, I understand that some mailbox contain duplicate items after restore and merge mailbox.
    If I misunderstand your concern, please do not hesitate to let me know.

    Are you run Restore-Mailbox with AllowDuplicates parameter? Please double check in OWA.
    Besides, please run below command to check the structure of mailbox folder:
    MailboxFolderStatistics “identity” | Select Name,FolderSize,FolderAndSubfolderSize

    If the issue only occur on Outlook client side, please run Outlook with online mode or reconfigure a new profile for testing.

    Thanks
