CX3000 Lync phone is unable to connect Calendar RRS feed

  • Question

  • We use room resources in Office 365.  Ideally, I'd like to use the same 'meeting room' resource on the CX3000 device for that room.  I really just need the calendar integration but is not working.

     Error : Connection to Microsoft exchange is unavailable due to invalid network credentials. For details, press the Menu button and select Notification.

     Please help me to resolve calendar issue on Lync phones
