Can confirm that the command is working now and it propagates too. Hooray!

It is still not working for me either 😞
Can it be that the extra line under the error message has something to do with it?Set-UnifiedGroup -Identity "MYGROUP" -CalendarMemberReadonly Write-ErrorMessage : Object reference not set to an instance of an object. At C:\Users\<myupn>\AppData\Local\Temp\tmpEXO_hxn1vmy2.kes\tmpEXO_hxn1vmy2.kes.psm1:1159 char:13When I open this tempfile and look at the code at line 1159 it has this Powershell command:
Write-ErrorMessage $ErrorObjectMakes some sense as the errormessage alse mentions this. Seems that an errormessage has to be written to the screen, but that it goes wrong?
