We have a list which has a person (people picker) column. This column pulls from (is validated against) several possible sources including Active Directory. If a name cannot be found when adding/updating a record then the following error message appears in red just below that field:
No exact match was found. Click the item(s) that did not resolve for more options.
We have a particular record we are trying to update. Per security policy former employees must be deleted from AD. Now, however, that the person in the person column of this record has left it is impossible to update his record due to the mentioned error message. His name won't validate even though he still exists in the User Information List.
How can this be overcome? Is it a configuration issue? It must be possible to update the record of a person who has been deleted from AD; otherwise, this would present major issues to organizations. We are considering using text for person names instead of system-validated person columns and clearly that would not be Microsoft's intent.
