Sync (or Sim) phase ends with: LegacyExchangeDN Failure

The default LegacyExchangeDNmapping is:

legacyexchangedn=~~legacyexchangedn~~/cn=Recipients/cn=~~smtpname~~.~~smtphost~~

Typically, the the use of a destination Domain Admin login ID allows the sync to automatically identify the correct destination legacyexchangedn root value. However, we have seen instances of this error even when using Domain Admin.

At sync time, if successfully identified, you will see the destination legacyexchangedn is synced without error.

If unsuccessful, the following error will occur on sync. This error must be resolved before the sync can continue.

This error can be fix by manually adding an override to identifiy the valid legacyExchangeDN .
