We built a new Unity UM server and moved users via Global Subscriber Manager and changed their Voice Mail Profile with no issues.
Originally we had not installed ViewMail for Outlook on users computers as they didn't want IT to support it, but found some users had secretly installed it!
I don't recall how to change Viewmail for Outlook 5.0(2) to use the new servers and don't see in Outlook where the VMO settings are.
I'm hoping for either registry change or Tools > Options in the menu.
I remember in the old days when running in Failover you had to manually change VMO, but don't remember what I didâ¦.
