Restore Teams private chat history to new mailbox
Hi, I'm having an problem with restoring Teams chat history to new user accounts and and their mailbox. I disabled Azure AD sync for a few users and deleted their account in the cloud tenant from the recyclebin and enabled the sync again to solve an issue with calendar syncing with on-premise mailboxes. Unfortunately their Teams chat history also vanished from their Teams account and now I'm searching for a way to restore their history. I can see the deleted mailboxes and should be able to restore the whole mailbox to a temporary account but I have no idea if the missing data is in there or how I can move the Teams chat history to the new mailbox. Can anyone give me hint or solution? Thanks and Regards
