Exchange calendar not working on El Capitan

When I have an issue, I always take the path of least resistance - i.e., I try the easiest fix first. Well, this worked beautifully. Just an un-check and a check and BAM! all my Exchange calendar events re-appeared. Thank you!

Oops - this is the solution that worked for me. Thx, "s2s"...

System Preferences / Internet Accounts / Exchange / Uncheck Calendars, then check Calendars again. This works for me.

This worked for me as well.

There is obviously some kind of issue caused during the El Cap installation.

Ok, apparently somewhere Apple fixed the problem with an update. Magically today it is working. After trying everything here I could not get Exchange and the El Capitan Calendar App to sync. So why it suddenly started working is a mystery, but I suspect a quiet patch from someone.

BTW, the "Solution" proposed here is hardly a solution. Many of us do not have multiple Mac's to copy settings from. I really wish there were a way to downvote a solution on these boards to indicate that the solution is not in fact a real solution.

Thank you, that has sorted the issue for me.

This worked for me also. Easy fix but should not be necessary!

Since upgrading to El Capitan I cannot open my calendar. I have tried re login into my iCloud but I still get the message Calendar cannot open every time I click on the icon. As t is an important work tool for me, this is really distressing.

Fixing Mac Calendar to work with Exchange on new El Capitan OS

When El Capitan launched, the Mac calendar stopped working when linked to Exchange accounts. This happened to myself and others in our office. I escalated the issue to Apple and their engineers provided me with a fix, and it worked for my colleagues as well. See below.

Follow these steps exactly as written:

1. 1) Turn off Internet connection and all apps running in the background. Then, Opt+CMD+ESC keys and force quit anything else running. At this point, Finder should be the only thing showing.
2. 2) Top Menu, click Go and then hold down Opt key. Library will appear. Click to Open.
   1. Drag Caches and Calendars folders to desktop
   2. Open Containers and drag to desktop
      1. Com.apple.calander.agent
      2. Com.apple.ical
3. 3) Open System Preferences and delete the Exchange account
4. 4) Reboot
5. 5) Turn off Internet connection and all apps running in the background. Then, Opt+CMD+ESC keys and force quit anything else running. At this point, Finder should be the only thing showing.
6. 6) Top Menu, click Go and then hold down Opt key. Library will appear. Click to Open.
   1. Drag Caches and Calendars folders to desktop
   2. Open Containers and drag to desktop
      1. Com.apple.calander.agent
      2. Com.apple.ical
7. 7) Turn on Internet
8. 8) Add Exchange account
9. 9) Open Calendar

The calendar takes a few minutes to sync with Exchange.

Worked for me too! Thanks for the tip! / Per
