Another User or Device is Deleting Mail

Problem: Emails seem to be deleting themselves after a certain number of days.

Cause: You are most likely sharing your email with someone else in the company or you have the account set up on other devices. The email account on one of those other computers/devices were set up as a POP account and the account was set to delete from the server after X amount of days.

Solution: You need to go to every device or person’s computer that is actively using that account, go into the settings and uncheck the box to “Remove from the server after X Days”
