We will be defragmenting the Exchange database, which may take 3-5 hours. Service will resume once the defragmenting is complete.

The defragmentation of the Exchange database on FONTUS took about two hours longer than anticipated, but completed successfully. I apologize for any inconvenience caused by the extended downtime of Exchange service.
EECS Exchange service has resumed normal operations.
