Installation of “Microsoft Exchange Server 2007 Service Pack 3 Unified Messaging Language Packs” caused us an issue which i would like to share
After installing this patch, user language prefrence will changed to english. Who ever calls the extension is hearing in English.
After going throught the basic stuff like, disabling and enabling UM in french for the user and resetting the pin, nothing worked
Atlast, one of my collegue helped to get this sorted out, asking me to follow the action plan
1. log in to OWA
2. log into their mailbox.
3. Click the Options button in the top right corner.
4. Click the Regional Settings option on the Right pane.
5. In the Language field have them make sure its set to preferred language
6. Make sure they hit the Save button after they have changed it.
7. Log out.
