We are having a weird issue with one of our users. I can't seem to find much pertaining to it via googling to death. Anyway, the user is on a MBP with Office 2011. When said user is sent a calendar invite from an internal source, it is added to his calendar. Everyone can see it on his shared calendar, on the users iPhone, etc. Now, when the user gets an invite from a client with an email address outside of our umbrella, it adds to the calendar seemingly without issue. However, it is not visible on the users iPhone nor the calendar share.



I first thought it might be an issue with archiving, but I unchecked "On My Computer" and nothing changed so I'm assuming it's not related to archiving. I've also seen issues when a user has multiple inboxes that forward to another one. Both calendars need to be set up, even though the invite was forwarded to the other inbox. This user only has one inbox but a couple of aliases, so not the same. I also messed with share permissions, but the user has them set up correctly(not busy/free, which doesn't work cross platform supposedly). I've wondered about clearing the calendar cache, but it seems to me that only helps for forwarded meetings.

Any ideas?
