Deleted mail continues to show up time and time again. How do I completely delete it?
I spend time deleting unwanted emails and somehow they will continue to show up again - even after emptying the trash. So annoying, How do I make them go away for good?
Sometimes when a mailbox behaves like this it's because of another program or app the account is being accessed from. Syncing issues between the account and a mail app can cause emails to be moved around oddly.
If you access the account through a mobile device or app, you may want to remove the account from the device and re-add it to resolve any syncing issues in the future.
