AppInsight for Exchange - Database File And Transaction Logs Dir Info Critical Status

I have a couple suggestions for things to check.  First, if you hover your mouse over the bar in the 'Database Usage' column of the 'Database File Size' resource (in your screenshot above), what does the hover look like?  Is it red like this?

Also, if you navigate to the details page of that AppInsight for Exchange application (not the database details, but the application details), what do you see in the "Mailbox Database Size and Space Use' resource?  Any red there?

Susan,

     Yes I got those same screen shots, but my whitespace values are GB in size

Susan,

     That got me pointed in the right direction.  I was able to shrink down the DBs using this blog post: Defrag an Exchange Server 2010 Mailbox Database.  Once I did that the error went away.  Thank you again for pointing me in the right direction.

Glad to hear you got it fixed!  The Database File And Transaction Logs Dir Info monitor has a 'Database File Whitespace Threshold'.  It's default values are greater than 25% for warning and greater than 30% for critical.  I believe this percentage is comparing the white space to the database size - so if your white space is more than 30% of your database size, the database will go critical.
