several email accounts showed up on a computers outlook app. These accounts were not added by the user and there doesn&amp;#39;t seem to be any PST files associated with these accounts. The user tried to remove the accounts by deleting the email folders, but that did not work. there is no email setup for these emails but they still have been receiving new emails.
The accounts (firstname.lastname@example.org and email@example.com) are two of the 5 email accounts that just showed up under this outlook that was only configured for firstname.lastname@example.org.
What can be done to remove these accounts and how did this happen?
