GUI vs CLI (Graphical User Interface vs Command Line Interface)

Sometimes it is better to use the CLI to make changes to users. Some common use cases are AD, Exchange, and on-prem Skype for business.

Shared email accounts in exchange do not show the Send-on-behalf permission within the ECP GUI, however this property still exists and can cause problems for users trying to send on behalf of a shared email account.

Set-Mailbox "SharedMailbox" -GrantSendOnBehalfTo @{add="Mailbox_needing_permission"}

Sometimes in Skype for business, the GUI will not successfully apply changes. Sometimes this is due to AD accounts

not having security settings inheritance turned on. If you run a command like the below, it should have no issue applying the settings:

Enable-csuser -Identity contoso\user -Sipaddress SIP:desired_sip_address@contoso.com -RegistrarPool skype-pool-name
