If your Exchange Server is down or an EDB database cannot be mounted, recovering individual mailboxes can be more practical than trying to restore everything at once.

One tool you can look into is Kernel for Exchange Server Recovery. It allows you to open and preview mailbox data from Exchange EDB files, select the items you need, and export recovered data to PST files or supported Exchange Server and Microsoft 365 destinations.

I would suggest checking this option if your goal is to retrieve important emails, contacts, or calendar items for backup or migration. Just remember to keep a copy of the original EDB file and verify compatibility with your Exchange version before beginning.
