    • Works fine when run locally.  I'm working on somethign that might allow this to be useful in an enterprise.  Currently you'd have to log on to each of your servers locally to have this script be valid.  Fine for a single server environment where admin is done on the server.  And useful as a means for determining smallest db size per server.  I took out the sort -property lenght ) [0] to make it return all of my db sizes per server. 
    • would I be able to use this as a variable, like $a? and then call it from within my script so the mailboxes are moved to the smallest DB? and then how can I have another var. that excludes a DB based on size?
