Does this happen on ALL meeting requests, or the ones being replied to that were generated before you 5.5 upgrade? I had this type of issue myself, where people would try and reply to a message or meeting request that was generated before the conversion and would get NDR's.

Acceptance or decline replies would always generate a copy to HR sec. Now, when that happens, the user would get an NDR saying that the HR sec name/address is not valid. Per our consultants request, I've removed all permissions from the HR spec mailbox. I waited about 4 hours after doing this and then tried the meeting request. Once again, an NDR was generated. I'm at a loss as to where to go now. Does anybody have any suggestions?
