Tag: Connect-ExchangeOnline

On February 12, Microsoft announced the deprecation of the Credential parameter for the Connect-ExchangeOnline cmdlet in the Exchange Online PowerShell module. The deprecation won’t affect interactive sessions (which should all be protected by MFA), but it might stop some background jobs running when Microsoft retires the server components that currently support the ROPC authentication flow. Time to check scripts!

After updating a bunch of PowerShell modules, I was dismayed to find a PowerShell module clash caused by a dependency on the Microsoft.Identity.Client DLL. The Exchange Online management module wanted a higher version of the DLL than the one loaded by the Teams module, so the Connect-ExchangeOnline cmdlet barfed. It’s easy to understand the logic behind the problem, but it’s hard to understand why Microsoft let it happen.
