While working on another issue, I noticed the Calendar Repair Assistan folder is not located in the default location. Instead it is located under C:\Windows\inf\MSExchange Calendar Repair Assistant. I checked the files in all subdirectories and with the exception of one, they all have the original Exch2010 install date. As far as I know, we haven't had any issues, but then I've never used this feature. Will this become a problem for us? thx, LM

Hello, I think it will not be a problem. You can also check the Application log about Microsoft Exchange Mailbox Assistants service. It will generate warnings or errors if there are any problem.
