Hi Darpan,

Could you help me with a similar and urgent issue? The difference is that I am on Windows and not on Mac. At the beginning I had the exact same issue, Calendar in Ms Teams simply would not load. I kept pressing "try again", logged out and in a couple of times, restarted my laptop, and worked in some of the Ms apps such as Calendar and Mail to see if it'd help. After a while, it got worst. Now the Calendar tab on Ms Teams simply does not appear! I tried the desktop app and web app, in Google Chrome and Ms Edge, and in another laptop. I could not find the folders on Windows to clear the cache, but if the problem did not solve in another laptop, I don't think it is a cache issue, right?

Could you help me?

Hi LucasA-Garcia,

Thank you for your reply in our forum community.

Based on your above mentioned reply. Can we re-confirm from your side that does this issue has happened with other user in the organization?

If you are using Windows, at once we would like to suggest you to kindly try to clear the cache of Microsoft Teams, try to see the result.

Following are the steps:

Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.

1. Go to File Explorer, and type in %appdata%\Microsoft\teams.

2. Once in the directory, you’ll see a few of the following folders:

a. From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.

   *   %appdata%\Microsoft\teams\application cache\cache

b. From within ‘Blob_storage’, delete any files that are located in here if any.

   *   %appdata%\Microsoft\teams\blob_storage

c. From within ‘Cache’, delete all files.

   *   %appdata%\Microsoft\teams\Cache

d. From within ‘databases’, delete all files.

   *   %appdata%\Microsoft\teams\databases

e. From within ‘GPUCache’, delete all files.

   *   %appdata%\Microsoft\teams\GPUcache

f. From within ‘IndexedDB’, delete the .db file.

   *   %appdata%\Microsoft\teams\IndexedDB

g. From within ‘Local Storage’, delete all files.

   *   %appdata%\Microsoft\teams\Local Storage

h. Lastly, from within ‘tmp’, delete any file.

   *   %appdata%\Microsoft\teams\tmp

Also, at once we would like to suggest you to kindly try to login to Microsoft Teams on mobile device, try to see the result.

Hello Darpan,

I cleared the cache and all files as suggested by you. However the problem of calendar not loading still persists. My team is using windows and they also have the same problem. 

I tried to schedule a new meeting, and when I go to save, I get the following error.

Hi Darpan, thanks for your reply!

I've found and cleared most of the files and folders you mentioned. But unfortunately it did not solve...

• Adding further information to see if it helps, I could not find the Calendar in the mobile app as well.
• The subscription that I have is the Office 365 A1 Plus for Students, which from what I have read, I should be able to see calendar, hence schedule meetings on Teams, shouldn't I?
• The other laptop that I tested was still using my own account, not a different one. Also, the weirdest part is, why would I have the Calendar tab available at first (it just simply wouldn't load), but then it disapeared at the same day?
• I have multiple accounts on my laptop. The main one is a GMail Microsoft account (administrator) and the one with the Office 365 subscription is a different one, from my University. I worry if there is some conflict between them, but at the same time, I don't have any problem with the other Office apps whatsoever...
• Finally, I read somewhere that the issue might have something to do with Ms Exchange. Which I could not find anywhere in my PC od Administrative services...

Thank you once again.

Lucas
