Following a Migrate Data job, the following warning is listed in the migration logs:
12:17:05 WARNING: [7359-199-14-8004011B] Unable to duplicate property array to get entry ID, role: 'SENT-REPRESENTING', name: 'Example Name', address: 'firstname.lastname@example.org', message ID: '
MAPI was unable to get the data because it contained corrupt data.
This was caused by an Exchange 2010 Throttling issue.
The Steps mentioned in the NME Admin Guide section titled:
"How Do I Migrate to an Exchange Environment with a CAS Array?"
