Exchange 2016 cu5 - cu18: seriously went wrong. RRS feed

  • Question

  • It would be a very long story if I'll  try to explain the whole situation. But I do it with some words.

    1/ Situation: exchange 2016 cu5. Goal: update to cu18. 1 forest, 3 domains. It went totally wrong. We opened a case at Microsoft for 600€ but after 3 days (they claim to answer within 2 hours) and 9 calls from myself (they never called me back) I withdraw the case and asked the money back. They just didn't want to help (unbelievable). Money back=ok.

    So during the update we got some errors I can't remember but we restored a snapshot and the exchange 2016 is working again with some little minor issues.

    That's the story, now the question.

    2/ When we search for our system mailboxes with Set-ADServerSettings -ViewEntireForest $true; Get-Mailbox -Arbitration we get 4 of them: systemmailbox 1f05..., federationmailbox 4c1f4d8...... systemmailbox e0dc1c29...... migrationmailbox 8f3e7716....

    So if I am correct for Exchange 2016 cu5 there have to be 5 of them. For cu18 there would be 7 required of them.

    To recreate them I have to execute: setup.exe /iaccept..... /prepareAD. (executing with the setup finded in the cu18). But when doing that the system is saying:

    a reboot from a previous installation is pending. Please restart and rerun setup.

    After a restart everything stays the same. So it looks like a loop. Any executable tips? executable= the Exchange server is a production server. In normal circumstances I cannot reboot during working hours and after those hours I can only reboot during the night.

    Can I solve this?

    Kind regards

    Kurt

    The Exchange Server (non-development) forums have been migrated to the new Microsoft Q&A platform, I suggest asking over here:

  • Hi KurtSt,

    Exchange Development forum isn't supported by Microsoft. Exchange Forum has been migrated to a new home on Microsoft Q&A

    So, I help you open a new thread and post a suggestion on that new forum: Target link. We can continue to discuss the issue in that new thread.

    If you have more questions about Exchange server, welcome to post them in that new forum. If you have question about script or EWS development, you can keep post in current Forum.

    Regards
