Copying Microsoft Exchange Server libraries

When recovering Exchange mailboxes or mailbox items to Microsoft 365, you may need to copy the following libraries from the machine that was backed up (or from another machine with the same Microsoft Exchange Server version) to the machine with Agent for Microsoft 365.

Copy the following files, according to the Microsoft Exchange Server version that was backed up.
