@Michael Cho
Thank you for your post!
When it comes to the Set-AzureADGroup command, you should be able to change a group name by using the -DisplayName
parameter.
#After running this it took about 1minute for the name to update
Set-AzureADGroup -ObjectId "groupObjectID" -DisplayName "changeGroupNameTest"
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
