GroupID Mgmt Shell Update-Group

According to the mgmt shell documentation, I should be able to run this command to udpate all the groups found in the specified ou.

Update-group -searchcontainer "OU=Dynamic,OU=Global Distribution Groups,DC=company,DC=com"

 

However it's asking for the identity of the group, which it shouldn't be.   This container is where all of our dynamic groups are.
