Hybrid Configuration Wizard fails on legacy email address types in Office 365 Dedicated/ITAR

Symptoms

When you run the Exchange Hybrid Configuration Wizard, the wizard may fail and generate an exception. This symptom occurs if the “CCMAIL:” or “MS:” legacy email address types are present in your email address policies.

Cause

This issue occurs when these legacy email address types correspond to CCMail and MSMail connectors that were removed from the product during the Exchange 2007 release cycle.

Resolution

Before you run the Hybrid Configuration Wizard against the Exchange Online "Dedicated vNext" tenant, remove CCMAIL: and MS: from your email address policies on-premises. For more information about how to do this, see the following KB article:

More Information

For more information, see the "Appendix D – Summary of Hybrid Server implementation" section of the Exchange vNext Topology and General Guidelines.
