Overwrite Import Error

Overwrite Import Error

I have a file that I am trying to do an import using overwrite.  I imported with the overwrite option.  It is telling me it skipped over 90% of the accounts.  I am getting this error;

Permission denied, record owned by another user

I have never had an issue before, I use this to queue up calling data for views.  I will not own the records, as I am the admin.

please advise, I need this to have my reps follow up.......
