Connect-ExchangeOnline stopped working between 5.3.3 and 5.4.4

Product: PowerShell Universal
Version: 5.4.4

Connect-ExchangeOnline, part of the ExchangeOnlineManagement module won’t connect any more in 5.4.4

I’ve updated ExchangeOnlineManagement module to latest version but problem persists.
I rolled back to 5.3.3 and it works without issue.

Anything I can do to get this running or is it going to need to wait for a fix?

I have the same issue, I had to make sure the script was running in integrated and couldnt use 5.1 or PS7 profiles

I wish there were a more permanent solution to the recurring issue of assembly version mismatch. I can recall this issue from UD times.

I opened an issue here. ExchangeOnline Module Not Loading · Issue #4592 · ironmansoftware/powershell-universal · GitHub

I also agree with trying to find a more permanent solution. I’ve considered some sort of module validation automation. We could do some sort of scan to of the PS Gallery for updates to popular modules, install them in PSU (maybe even a mix of them) and then do a couple operations to catch these basic failures. We could then publish the report so you could see which versions of which modules work with PSU.

Without this, it is a never-ending moving target on either end.
