Hello

I'm doing a migration from 2007 to 2013

I have migrated 2500 users, but there are 4 that wont migrate

The error is 

MigrationPermanentException: Error: Multiple objects with Sid S-1-5-32-544 were found

Its the same sid on everyone, a standard sid for local administrators group.

I was thinking it was something with full access rigts to the mailbox, but I cannot understand why its reacting to the standard sid.

Regards
