Suddenly unable to connect to Exchange Online via Powershell

Question

Hi,

Suddenly (started on 13 of March) I can't connect to the ExchangeOnline via Powershell.

With no changes to the infrastructure I started getting the following error. Could you suggest troubleshooting steps, please?

An error occurred while sending the request.

Files\WindowsPowerShell\Modules\ExchangeOnlineManagement\3.1.0\netFramework\ExchangeOnlineManagement.psm1:729 char:21

Hi @Tomasz Kasinski ,

 

“Thanks for insight. It turned out it is one of those hundreds unknown Microsoft errors. I have deleted my Windows profile and re-created a new one and all errors are gone. As usual not the most elegant way but we used to it when it comes to the Microsoft products 😃”

Hi @Tomasz Kasinski ,

Based on your description, we have the following suggestions to troubleshoot our issue.

1. 1. Please confirm whether other administrator accounts can connect. Or whether it is feasible to use other machines to connect.
2. If other admin accounts can connect normally, it is recommended to use the following cmdlet to view the remote PowerShell access status for your account.

  Get-User -Identity "<UserIdentity>" | Format-List RemotePowerShellEnabled

3. If none of the above works, check the service health status on the M365 Admin Center and see if there’s any potentially related advisory.
