Exchange collates mailbox database offline

After using Exchange mailbox database for a period of time, due to various reasons, the database will produce a large number of fragments, the size will become more and more bloated, and a lot of disk space will be wasted. Therefore, the database can be defragmented offline on a regular basis to free disk space and reduce the size of the database.

1. Uninstall the database unmount first

2. Enter eseutil / d "f:\ ExDB\ Technical Center\ technical center.edb" / t h:\ techtemp.edb in the command window. The parameter / t is followed by a temporary database, which is generated when the database is defragmented offline and will be deleted automatically after finishing. Be careful to prepare enough space for this temporary database, which is about 1.2 times the size of the database to be sorted out.
