I have6 MailBox servers. I can view the disconnected boxes of the servers, but there is one in particular that the MMC crashes upon. I have done this from several different Exchange Servers and get the same result on the same MB server. I run this in the EMS: Get-MailboxStatistics -Database "Mailbox Database" | where { $_.DisconnectDate -ne $null } and it returns without error. I wonder if there is a bad MB & this will go away in 30 days or less, or if there is something wrong with that server in particular. Any ideas? Thanks

Hi, First try to clear the views in your profile: To clear the views, start-> run MMC, in the console window, click file->options, then go to the Disk Cleanup tab and click delete files. Second, run the ExBPA to see if any error and try to fix it. Try on another servers/workstation where Exchange Management Tools installed to see if same result if not then it is particular server issue. EMC uses .Net, MMC & Powershell to get the GUI display of Exchange 2007 so you can think of SP1 with UR2 installation if it is not installed, that may overwrite any faulty dll or required file.

Hi, Please first let me know the exact error message that you received when EMC crashed. Regarding this issue, please run the clean-mailboxdatabase identity Mailbox Database command After that, please check this issue. Thanks Allen
