Hello, Ive been having some issues with an exchange calendar not syncing events onto my mbp for the last month or so, and now mail also just seems to hang when downloading messages/checking for mail. If I quit out of mail and restart it, then the messages download, but when another email arrives it just gets stuck on downloading until I quit again. Is anyone else having similar issues? Mail is arriving just fine onto my iphone, and onto my work PC. If I accept calendar invites on my mbp they sync to other devices, but if i accept on my phone they dont appear on my mbp.....its getting more than a little bit frustrating
