For a test, try eliminating all of the stuff in ToString() and use a manual value.  There were some service packs released recently for Exchange 2007, that could have affected some things.  If you can get it working by using a manual value rather than using the ToString() function then you will know it is just a syntax issue.

Does it crash out on the first mailbox, or does it get part of the way through the Get-Mailbox results before crashing? Try adding


as the first line inside the foreach loop. I think that should be enough to display each mailbox display name, so that you can see if it processes any at all.
