I do all my email account via IMAP.

You are unchecking "Try to get e-mail settings automatically" right?

Then are you selecting Internet e-mail as the provider? Then your name and account name? Then you know and enter your Incoming mail server? Typically imap.servername.com where servername varies. then you select account type as IMAP?

Then the right username and password? You say you already have this IMAP server working in Outlook on the PC?

Then the outgoing server name? Typically smtp.servername.com? Check authentication?

Does this all sound like stuff you've covered already? Then perhaps you do need help for your particular IMAP server.

I recall Gmail IMAP setup instructions requiring certain port numbers to be set for the PC but I don't think so from mobile.

Just wanted to see if we are on the same page. My IMAP is working for several accounts.
