And is this still on the email server?
For example, my deleted emails are still on my google email account when I look for them with a web browser. So not only do I have to delete them on my email app (you should reveal which one) but I may have to go to the email server via a web page to really dust them off.
Delete Messages in Mail are still in my Inbox! They are Grey, but I can still open them.
Also, Filtered Messages are still in my Inbox.
I have never seen this happen before.
How can I fix this Problem?
