Im trying to get my free GMX mail to sync using IMAP to my WP7. I am using my username and password as you would expect and:

Incoming Server: I have also tried ..:143 (so without SSL) and I have deselected/selected the SSL options under advanced for each. I have also tried with and just plain address with no port number.

It appears as though I am the only one having this trouble, all Google Search's reveal are instructions for setting generic devices.

I managed to get POP working, but would prefer IMAP.

You asked a very specific question. I only can say that I am currently using Windows Phone with IMAP and Exchange accounts. – Vitor Canova Feb 2 '13 at 11:36
IMAP is a GMX premium feature. Did you upgraded your account? – Marcel Janus Jul 2 '14 at 11:48
@MarcelJanus No, not for the version at least. What version are you on? – tim.baker Jul 3 '14 at 11:34
@tim.baker I looked in the German FAQ – Marcel Janus Jul 3 '14 at 11:54
@MarcelJanus ... then I guess it must be for the German version of GMX. Either way think this should help if you do have IMAP – tim.baker Jul 3 '14 at 13:21

My GMX account works with as the incoming server. My user name is my email address (the primary one if you've set up aliases).

Under "advanced settings" I've got "Require SSL for incoming email" checked.

So I have struggled with this a few times; in the hope this helps someone else follow these steps.

A couple of notes:

  • These instructions include details for GMX mail, but it should help if you are having issues with receiving email on your Windows Phone
  • Set up like this I have avoided most error messages including "there is a problem with the certificate for"
  • These are instructions for using IMAP; you can adjust for using POP though I'd always recommend IMAP
  • You will notice the server is; I have a address and the two play nicely together
  • After the "Incoming email server" notice how I have not entered any port numbers (some sites suggest

1. Start fresh

It has given me problems before because it has recognise the email etc - so delete the email account if you have already tried to set it up.

2. Go in to Settings>Email+Accounts>Add an Account>Advanced Set Up

Make sure you select advanced and not other account

3. Enter your email/password

4. Select "Internet Email"

5. Set the following settings

  • Account Name = Whatever
  • Your Name = Whatever
  • Incoming email server =
  • Account Type = IMAP
  • Username = Your GMX Email
  • Password = Your password
  • Outgoing =
  • Outgoing server requires... = CHECKED
  • Use the same username... = CHECKED
  • [Advanced] Require SSL for incoming = CHECKED
  • [Advanced] Require SSL for outgoing = BLANK
