I currently have my office on Office 365 with DirSYNC.
We are rolling out Lync online to users. We used to have Office Communicator and the SIP ID are now a part of the users AD account.
I need to clear the current SIP ID in field msRTCSIP-PrimaryUserAddress. I know how to do this manually and Office Communicator was used a long time ago, but there are about 400 updates I would need to perform.
With DirSYNC the accounts in Office365 are locked out so the changes must be made locally and Synced up to the cloud.
I'm fairly new to scripting, so I am just starting to get the hang of things.
