10-Apr-17 11:05:54 AM: Thread ID 29: Dell.UC.Insights.DataEngine.DataCollector.DataCollectionJob (IL Offset 0x64): Caught exception: Unable to process the IIS log file.
AggregateException: One or more errors occurred....
Inner Exception:
TooManyMatchingUsersProblem: Too many Active Directory users match user@domain.com
...
Causa

A search for the UPN listed in the error "Too many Active Directory users match user@domain.com" returned more than one result. There is more than one user in the forest that shares that upn.
Risoluzione

Remove the duplicate UPN
The following powerhsell command should return all users with the UPN in question.
Get-ADObject -LDAPFilter '(userPrincipalName=*user@Domain.com*))'
If you have multiple domains in you forest you will need to run the command in each domain.
Once you identify the object with the duplicate UPN modify the UPN so it does not conflict.
