Don’t you hate when you get that call, and it’s 3:30PM and it’s not good news. Well, I got that call and it was due to email being down. NOT GOOD!!!! Our mailbox store was not mounting and we were getting this error:
When you try to mount a database in Microsoft Exchange Server, you may receive the following error message:
An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
