OSX Calendar not showing Exchange Account So because the mail app from Apple is far from perfect and never showed me the date and time of calendar invites from MS Exchange environments (after the Yosemite update) I was adviced to re-add the exchange account in Preferences -> Internet Accounts.

After doing that, the calendar app just won't show the exchange account anymore. It's right there in the settings, but not in the panel:




Can anyone tell me how I get my exchange calendar back to the calendar app?

Thanks in advance for any help.

PS.: the bug in mail (no date&amp;time for cal invites) wasn't fixed by this btw.
I feel stupid for answering this myself because the "fix" is idiotic.


Remove the exchange account
Restart the mac
add the account back -> everything works.


I hope another answer gets two upvotes if they help someone so they're assigned the bounty I put out on this question.
Thanks for the answers!
