I used to have the sole email account on my phone setup as POP and recently changed it to IMAP (gmail). When I had POP setup, I could receive calendar invites from other BB users where I could accept, reject, etc., the invitation. However, since I setup my gmail as IMAP, all invite related emails skip my BB and only show up on the gmail site/outlook.

Every single other email is delivered to my BB but for those that are calendar items. Why?
