Why GMX Mail not Working? – [SOLVED]

Are you facing problems setting up GMX account? Frequently facing errors when trying to access GMX webmail in a third-party email client? If yes, then we are having troubleshooting suggestions that can help to setup GMX account in a required account.
If you have put efforts to configure the GMX account in the email program but still it is not working, then in such a situation an error message will appear. There are multiple reasons behind this issue and some are explained here:
Turned Off POP3/IMAP
By default, the POP3/IMAP remains disabled in a GMX webmail. And due to these options, one can retrieve email messages. If you wish to receive emails with a third-party email client, then activate POP3 & IMAP in email settings.
Error Message in a Mailbox
At times, error messages such as temporary blocks may not appear appropriately in a third-party email client. Login to GMX account straight away on a Mac and check if error message is displaying on the screen after logging in. This will then hold the further instructions to fix the error.
Incorrect Server Details
You have provided wrong server details.
Verify the Server Details
Inbox (IMAP) | Inbox (POP3) | Outbox (SMTP) | |
Server | Imap.gmx.com | pop.gmx.com | mail.gmx.com |
Port | 993 | 995 | 587 |
Encryption | SSL or encryption | SSL or encryption | STARTTLS, TLS or encryption |
If STARTTLS is not in the application, then use TLS protocol. If neither of the option exists, then activate the Encryption option. Alternatively, one can use Port 465 for outgoing mail server with SSL encryption.
Note. You can use TLS protocol if the email program make use of TLS versions 1.2 or 1.3. For security purpose, GMX does not support older TLS versions 1.0 or 1.1.
Incorrect Settings
When you manually setup an email profile, then the input settings such as the outgoing mail server needs authentication. If the email account is automatically configured, then there are a few settings that are set by default which can be incorrect.
Check the Settings
Go through the information given to set up the email account in GMX Help Center. Check if the settings are matching the instructions. If the account is automatically set, then delete it and configure it manually.
Incorrect GMX Login Details
You entered the wrong email address and password of the GMX account.
Cross-check Email Address & Password
Check the login details by logging into your email account via the gmx.com webpage. You can reset your password if you are not able to remember it. You can get more information on how to do it on the GMX password recovery help page.
Issues with Security Applications
At times, the installed security applications on the system such as a virus scanner or firewall prevent sending/receiving emails.
Check Security Software
Verify the settings of security software. And, if important then immediately contact the software vendor.
Email Program is Outdated
The Outdated email application will be unable to fulfill current security needs.
Change Email Application
Move to an enhanced email application such as Thunderbird.
Still, if you are facing the same issues, then it will be better to transfer your GMX email account to a more secure, updated, and reliable email client.
