Event ID 9688

Exchange store 'First Storage Group\Mailbox Store (XXXXX)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 68 GB. This database size is approaching the size limit of 75 GB.

If the logical database size exceeds the maximum size limit, it will be dismounted on a regular basis

This error mentions what is the maximum size of the database allowed for the edition of Exchange server you have and you need to do one of the following:

1.  Delete messages, mailboxes, empty deleted items, etc.
2.  Move mailboxes do different database (you may have to create new one)

Refer to following two links:

Goto the reg key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<SERVER NAME>\Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00

Add the DWORD value "Database Size Limit in GB" and set the limit you wish to have set in decimal form (not HEX) i.e. 100.

You then need to restart the Microsoft Exchange Information Store service. You can then check the application event logs for event 1216 i.e.

The Exchange store 'First Storage Group\Mailbox Database' is limited to 100 GB. The current physical size of this database (the .edb file) is <1 GB. If the physical size of this database minus its logical free space exceeds the limit of 100 GB, the database will be dismounted on a regular basis.
