I am going to integration Cisco unity server 7 with microsoft exchange 2010 .... please share me if there is any possibilities of failure of this task or what are the milestones during this process , where i have to be very conxiuos ?
Thankyou in advance.
Unity 7 is not compatible with MS Exchange 2010:
what do you mean is not compatible??
see this document
I stand corrected. You found a more recent document than I had.
It looks like that link provides the steps necessary to complete the integration.
As for your specific questions...
Things can always go wrong so no one will tell you there is no possibility for failure. Make sure you have a good tasklist and plan for the integration. Have a backup plan in case you run into problems. Also make sure you have current backups for both the Unity and Exchange servers.
