I have a user using Outlook 2010 to open a share calendar of a user who is using Outlook 2003. Both users are in online mode and we are running exchange 2003. When he opens a recurring meeting on the share calendar, it opens up as new email instead of a meeting event. This does not happen on all the recurring meetings, just some particular ones. It happens on both outlook 2003 and 2010 (even if you load the profile from some other workstation). I tried outlook.exe /cleanprofile on the mailbox owner's computer but didn't resolve the issue. Any advise?
