Our outlook started this morning downloading old 2014, 2015, 2016, etc. emails, over 3gb of data. The account is an AOL account. We have the same account in another computer also with outlook 2010 that is always on for the purpose of maintaining a copy of the AOL email. The curious thing is that THAT outlook is not receiving old emails, it's working fine.
What can be happening and how can we stop it?
