Microsoft Planner "Server Error in '/' Application."

Question

Hi there,

I keep getting an error on my Chrome browser, but not on my Android app (which seems to be working fine). I have tried clearing the cache, but still get the same message. Below is the error message I get on the page. Any ideas?

Server Error in '/' Application.

Answer 1

Hello David,

Per the description shared, we understand that you are not able to access the Microsoft Planner in Google Chrome where clearing the cache doesn't resolve the problem, in this scenario, we would request you to access the Microsoft Planner in the different browser such as Microsoft Edge and check the result.

If the still same problem, can you please check whether other users in your organization are having the same problem?

Best Regards,

Chitrahaas
