For create a new subscriber, currently customer is able to either import from exchange or create from unity admin. This was done during the installation. Now customer wants only import. I went through the document, it seems there are two ways to do this:
solution 1. Permission wizard. Here is the step: choose the object to be able to created in AD. If we uncheck users, unity won't be able to create subscriber.
solution 2. Message store configuration wizard
Step 12: option 1:select create new account or import; option 2: only import. If select 2nd option also unity won't be able to create new subscriber except for import.
Is either of them working? which one is preferred? Thanks
