Gents, is there a way to prevent a user from accessing voicemail via the TUI, but still allow them to listen to it inOutlook?
I can think of a couple things you could try.
The simplest would be to change the Telephone User Interface (TUI) password so that they could not log in over the phone.
A second option would be to to create an Internet Subscriber account instead of a regulaer subscriber account and set the SMTP address to their Exchange mailbox SMTP address. Internet Subscribers can not log in to their account.
