Hi. I have on premise exchange server 2016. We have one user with archive . Unfortunately it got disappeared . I could see (0 MB in EAC) .I believe it is because Archive GUid so changed to Exchange online archive guid . The archive guid was different before. How can change it old archive guid in active directory users and computers ? The mailbox database whitespace has not changed meaning the archive is still there right.? I can't archive in user's outlook

    Hello @Jonathan Priyaraj,

    Welcome to the Microsoft forum for technical support.

    According to your description, you can change the archive GUID according to the following steps:

    1. Open the Active Directory Users and Computers tool on the server.
    2. Make sure you have advanced features enabled by clicking View on the menu bar and then selecting Advanced Features.
    3. Locate and right-click the relevant user account and select Properties.
    4. Navigate to the Properties Editor tab.
    5. Find the property named "msExchArchiveGUID". If it has changed and you know the old value, you can modify it back to the previous GUID. Please make sure you enter the correct GUID and the correct format.
    6. Click OK to save changes.

    A blank unchanged mailbox database indicates that the data still exists but is disconnected. It is recommended that you verify the status of the database and archive mailboxes using Exchange Management Shell commands, such as "Get-MailboxDatabase" and "Get-MailboxStatistics" for user archive mailboxes, to confirm that the mailbox data is intact.

    Please feel free to contact me if you have any queries.
