This question already has an answer here:
I am new to Sharepoint and I am trying to troubleshoot a problem with importing AD profiles on Sharepoint 2013
Anytime I run the 'User Profile Service Application' Job that is supposed to Synchronize the profiles, it fails shortly after and returns the error message:
Operation is not valid due to the current state of the object.
This system was previously working and I am picking up the responsibility with no knowledge in the way it was initially setup.
This issue been going for a couple months before I began to notice it and I am at a loss as to where to start troubleshooting.
-Another answer shared mentioned that when you are importing from AD, you may not need the FIM service; https://sharepoint.stackexchange.com/a/183098/64800
-My Sync connection is setup and populates when queried.
If you need anymore information or have any ideas as to where I should start looking, please let me know.
