Exchange 2019 Mailbox Migration Error - Folder conflicts with Exchange Online folder
Hi Exchange Experts, I'm migrating a small Exchange 2019 environment to 365. Been pulling my hair out becuase of just one mailbox giving this error Error description --------------------------- ...
My guess is that the user has created a folder called "Files" in their mailbox and this is conflicting with the system folder in EXO. Maybe have a chat to the user and see if they can rename it.
"Files" seems to be a system folder and you can't do much except renaming which we tried through MFCMapi with no luck, it still refers to the "Files' folder.
EXO shouldn't matter should it? as we're simply trying to remote move the mailbox and obviously there's no mailbox exists in EXO for this user yet.
