The same thing is also happening to me ALL the time.

It also happens to me when i run: Get-mailboxfolderpermissions, get-migrationbatch, get-migrationuser and a slew of other commands. Only happens when running ExchangeOnline commands. Mggraph, teams and such have given me no issues.

Hi @YM,

Thank you for posting to Microsoft Community.

Based on your description, I understand there is an error when you connect to Exchange Online via PowerShell.

The error message you offered could be related to syntax of command.

For that, you could refer to Connect-ExchangeOnline (ExchangePowerShell) | Microsoft Learn for more information.

Hi Noah,

I tried to connect using this command only: connect-exchangeonline, which opened up my company's sign on portal. I selected my admin account and then received that parsing error. I tried it this way: Connect-ExchangeOnline -UserPrincipalName chris@contoso.com and got the same error. I also tried it this way: Connect-ExchangeOnline -UserPrincipalName chris@contoso.com -Organization "contoso.onmicrosoft.com". Please advise as I'm not sure where I could be making a mistake in my syntax.

Hi,

If there exist issue with it, I suggest you could use command below to uninstall Exchange online module and reinstall it to see if it works.

Uninstall-Module -Name ExchangeOnlineManagement Install-Module -Name ExchangeOnlineManagement

You could refer to About the Exchange Online PowerShell V3 module | Microsoft Learn for more information.

If there are anything else I could help with, please feel free to contact me.
