I cannot recieve emails on 2 of the mailboxes i have in my Nokia E72 because the settings are incorrect. I have tried many different settings and still cannot recieve. So i tried to delete the mailboxes, but it will only let you delete the mailbox if you are connected to the server. Is there any other way of deleting the mailboxes?
I read a thread on this over on techarena the other week - just found it again, here.
If you still have no luck then there would always be the option of a factory reset (thougb be sure to back up your contacts and information first (Vodafone 360 is useful for creating a backup of your contacts and information)
