PowerShell - ActiveX Control Error
ColeRiese Does your script utilize any forms? (e.g. $form1 = New-Object System.Windows.Forms.Form)
I just got done going through this and was finally able to work around it. It is my understanding that there is a bug in newer versions of the Exchange Online module. If you are using any sort of forms in your script and those forms are called before you connect to Exchange Online it generates the error. If you connect to Exchange Online first, then the form is called, there is no issue.
I had to tweak our script to connect to Exchange Online first, then add a prefix to our on-prem exchange session to prevent any conflicts. Here are a couple links I found during my search that helped me track down the issue.

Hope this helps!
- Yes, I still got the ActiveX error
- Could you share the part of the script which gives you the error?
- This is the exact error that I get:
