Re-adding email account

[Salford]

Hiya everyone, wondering if someone can help me out please.

Over the weekend, my server which stores my website and email accounts etc was moved to a new one. So DNS etc... also changed.

I presumed that my email would just carry on working, but it didn't. So I've just ended up deleting the email account off my phone, and then re-adding it.

So it's now up and running again, however, I've got my message icon which now only shows emails received since I re-added the account. And another mail icon on the main menu, which has all of my older emails.

Is there a way to combine these? So that I can still see my old emails, and also have my new emails delivered into the same mailbox???
