Our Unified Messaging service was originally created using the "Specify the Hosted Exchange Server" rather than the recommended "Search for Hosted Exchange Servers". It has worked fine until a recent upgrade to Office 365, the specified server podXXXXX.outlook.com will no longer be valid.
I set up a new Unified Messaging Service using the "Search for Hosted Exchange Servers" option and that has tested as good.
The question is: how to change the 1000 users.
1. Change the existing Unified Messaging Service, which the users are assigned, to use the Search option?
2. Change all users to the newly created Unified Messaging Service. Can this be done using Bulk Update?
I would rather use option 1 but I don't want to make sure there is no problem with doing it that way.
