How to defragment Exchange databases

Assuming a server has hit the 16GB "wall". Also assuming that there is 16GB free space on the disk run:

ESEUTIL /d "E:\program files\exchsrvr\mdbdata\priv1.edb" /t "E:\program files\exchsrvr\mdbdata\tempdfg.edb"

Notes:

1. Disregard MS, the /p switch slows things down.
2. ESEUTIL is not in the path.
3. E:\program files\exchsrvr\mdbdata\tempdfg.edb is now the name of the defragged Private Information store.

Once defragging is complete:

• Rename Priv1.mdb to OLDPriv1.mdb
• Rename Tempdfg.edb to Priv1.edb
• Mount the Information Store
