The Microsoft® Exchange Server Analyzer Tool has determined that disk space on the computer that is running Exchange Server is below acceptable levels. The Exchange Server Analyzer measures available disk space to verify that it is within an acceptable range. If the tool finds that disk space is below acceptable levels, it displays an error message. It is recommended that all disks in computers that are running Exchange Server contain mailboxes that have at least 10 percent of their capacity free at all times.

The Exchange Server Analyzer tests the following drives:

Database drive
Temp drive
MailRoot drive
STM drive
System drive
Log drive

Note:

The state table calls for the log drive size to be increased and the logs to be archived.
Page drive

Note:
The state table calls for the log drive size to be increased and the logs to be archived.

To correct this error

To free up disk space, delete unnecessary files from the disk.
If the disk that has less than 10 percent space free contains data that can be safely moved to another disk (such as mailboxes or the Microsoft Windows® pagefile), perform the steps that are required to move the data.
Add disk capacity to the computer that is running Exchange Server.
Reduce the mailbox size or move users to another server.
