Microsoft Calendar app not working

Stuart · Mar 3, 2023

Many thanks wgt40w for the "idiots guide" which following the installation of the Microsoft update has succesfully restored my Calendar with all events still fully showing.
May I say that the kind help and patient assistance of all the "experts" on here is very much appreciated - cheers !!

HOW TO FIX - open Microsoft Store / on left Click Library - a list will show of the apps on your computer/ top right Click on Get Updates - wait a bit and hopefully from today Mail and Calendar will show an update of 38.47Mb - let this download and install.
After this you should be able to open Calendar OK - in my case Calendar opened with NO data showing - in Mail/ Click on Accounts/ Click on your email address account showing/ Click on "Delete this account from this device". Close Mail and then re-open it/ Click on Accounts/ Add Account and a list of suggested email addresses will show/ Click on the same email address as the one on the account you just deleted. After doing this - for me Calendar then opened showing all my saved calendar future events.
PS Unless you are lucky, this update appears to be the only 'certain' fix - as the problem was caused by a faulty Calendar app update that, for me came on 1st March.

This worked for me! Thanks a million

When I start the Calendar app from Start /All Apps/Calendar (or anywhere else) all I get is a splash screen for a few seconds then it shuts down. I'm on 22H2 2263.1325. It's not on long enough to get a screenshot. There's just a plain blue window with the calendar icon. Any suggestions please?

Mine is doing the same thing -- so I guess it is not just me.

I'm having the same issue...my Desktop PC with Windows 11 22H2 – OS build 22621.1344 -- the Mail app is fine, but the Calendar apps starts to open and immediately closes. Meanwhile, my laptop is running Window 11 22H2 – OS Build 22621.1105 and both Mail and Calendar apps work fine.
