We have conducted a deployment from CRM 2011 through to CRM 2015.
There were some users with multiple AD accounts which confused the mapping process. I had thought we had remapped all the users effected but it looks like we missed one.
How do I re-add/enable this user and associate them to all their old records?
I presume the records are all still there I just don't know what state a non-mapped user will be in and how to re-associate it with AD. Are we enabling and adding in the account to the record? Is this going to be more complicated than that?
