Lepide Exchange Recovery Manager tool quickly restores mailbox data from the corrupt EDB file. It’s a powerful EDB to PST conversion tool. It stores recuperated Exchange mailboxes or items in PST, EML, DBX, Text, RTF and HTML formats. LERM has simplified the process of mailbox migration from one Exchange server to another Exchange server. In the newer version of LERM, office 365 can be added as a source.
