calendar only opens half height since El Capitan

Hi Eerk

As reported here and other threads, Microsoft Exchange calendar seems to be causing this issue. Do you have Exchange linked to your Calendar?

On page 2 Graf Z reports that deleting then reinstalling the Exchange seems to fix the issue. Others are confirming it also worked for them. Assuming this to still be true.

A test is to use a clean user account on Mac that does not have Exchange tied to it, then resize Calendar and Quit. Reopening it should be in last "state" as when you closed it. This means it is not a "native" problem to Mac OS.

If the problem does not reappear after deleting Exchange and then re-installing, then this suggests at least 2 possibilities to me. The first is that the Exchange preferences (plist), which dictates things like screen sizes was poorly written and had a default screen size, or more likely, that MS rewrote the app to fix this bug and when Exchange is reinstalled, you are getting the new code.

You could try to delete the Exchange preference (plist) files and see if that works. If not then you would need to try deleting Exchange altogether, then I would recommend you restart your Mac, then reinstall Exchange.

Please let us know if this works for you, adds to the community knowledge base.

Hope this helps, Greg

Hi Graf Zeppelin,

I confirm that your tip also worked for me !!! 🙂

Thanks a lot !

As of 01 MAY, I have raised a case with Apple support which did a lot of troubleshooting withe me and raised a ticket with engineering on this issue. For me, it does seem related to Exchange as when I disable my Office 365 calendars the issue does not appear.

As a temp workaround, the tech advised if I click the "Calendars" button in iCal and hide the calendar listing, a resize does work even when quitting and relaunching the app. This did work for me.

I also have exchange accounts with this issue, switching to my daughter's account, who does not have exchange accounts, there are no issues.

Worked for me. Thank you!!!! I have several exchange accounts, I did this only with one account and it fixed the issue. Thank you, Thank you!

OMG, thank you. This has been driving me nuts for weeks. Deleting the .plist file worked for a while, but then it started opening half-size again. So far deleting & re-adding my Exchange account has worked.

HI Steve...

Thanks for the information this worked for me. All the others didn't so now pleased I have got this sorted out with your help. Its been a while since the update so I wonder why Apple has not picked this issue up.

Thanks for the advice though.

Cheers

I see three pages of response to this iCalendar problem. Why hasn't Apple fixed this simple bug in one of the many updates? I don't think previous management would approve of pushing the fix for a non-intuitive program issue onto users - Exchange issue or not.

Best Regards

This will probably never be fixed.

However, instead of trying to remember to hide the sidebar before quitting Calendar a quick Option-Click of the green window button will get your big calendar back.
