ADDITIONAL INFORMATION:
The following diagram shows the “Internal Microsoft Domain List” to be domain2.com, and domain1.com:domain2.com. This is the correct configuration for the diagram shown in the Microsoft federation with internal Avaya Aura domain and external Microsoft domain section.
The first entry “domain2.com” is used to federate in domain #2 between Microsoft and Avaya Aura users. The second entry “domain1.com : domain2.com” is used to federate between Microsoft users in domain #1 and the Avaya Aura users in domain #2. This configuration instructs Presence Services to use domain2.com as a tandem to reach Microsoft users in domain1.com.
