Cannot connect Exchange online with Powershell

Question

Hello

I have a problem to connect to Exchange online with a global admin account (MFA enabled).

Here are the errors I get:
1st error
New-ExoPSSession : Processing data from remote server outlook.office365.com failed with the following error message: Th
e request for the Windows Remote Shell with ShellId 4BC388B1-124B-41D9-87B9-42D6BD57990A failed because the shell was n
ot found on the server. Possible causes are: the specified ShellId is incorrect or the shell no longer exists on the se
rver. Provide the correct ShellId or create a new shell and retry the operation. For more information, see the about_Re

So far I have tested with other network and other computer with same kind results. I have the problem with several tenants and it has lasted at least a week.

One work around is that I can create a new global admin. With that it seems to work normally. But would there be possibilities to retain the original admin access?

Answer 1

Hello

Thank you @Xzsssss for the response. Here are further details.

It should be cloud-only and non-multi-region tenant. I get the second error over and over again, so trying another time does not seem to help either.

I also tried to remove GA rights and add them again but the error still keeps coming.

I hope these clarified the issue.

Hi @Pekka Pekkonen ,

For the first error, please check this document for help: https://learn.microsoft.com/en-us/exchange/troubleshoot/administration/invalidshellid-error-in-rps
See the scenario two: In this scenario, you should rerun the cmdlet. A different back-end server should be contacted, and then the cmdlet should run successfully.

For the second one, as it points out the "XXX isn't assigned to any management roles.", I think it's a permission mistake.
As you said you used a GA account to login the Exchange Online PowerShell and failed, but new created GA could work correctly. Would you like to share something about your environment? Is it a hybird and the former GA account lives on-prem?

Also please try re-assign permission to the former account, and see if this time it could work or not.

Best regards,
Lou

I am experiencing the same issue. The language setting does not seem to be an issue at my end as English is set as default language. Please, suggest..

Answer 4

Hi Steven,
I am supposed to use v5 at my workplace. I even tried uninstalling and reinstalling of exchange module but without any luck.

Answer 5

I was able to figure out the solution.

Steps:

1. Displays remotepowershell status: In my case it showed false

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

2) Now enable the remotepowershell for exchange online
Set-User -Identity <UserIdentity> -RemotePowerShellEnabled $true

3) validate: run step 1 and it should display true. I was then able to connect to exchange online through powershell

Hope it helps to those who have same issues.
