Calendar and Files Tab not working on Microsoft Teams

[Rebmif0011]

Hi everyone.

For the past 3 weeks I have been unable to access the calender and files tabs on Microsoft Teams. 
They are showing but when I click on them it shows that there's some sort of failure/error.
I'm a teacher and I need to schedule live lessons and upload worksheets so this issue is really a problem.

Can someone assist me in what I can do to maybe solve this?

Thanks

Are you able to share a picture of the error message in MS Teams?

@Rebmif0011  Was there a resolution to this problem? I am having a similar issue. I see the messages:

Couldn't load your calendar. Let's give it another try
