Settings to access your e-mailbox

For staff members: If your mailbox is located in the Exchange server, please read Access options to the Exchange mailbox.

To retrieve your e-mail from the central mailbox server of TU Chemnitz and to send e-mail via servers of TUC, you must use an e-mail program and set it up correctly. Alternatively (e.g. at home or whilst travelling) you can also use other access options – with minor functional restrictions.

From September 15, 2025, retrieving and sending emails via the central mailbox server with client programs such as Thunderbird, Outlook, Apple Mail, or apps will only be possible from the campus network. When working from home or on the go, you will therefore need to use a VPN (virtual private network). Read more …

For the e-mail programs Thunderbird and Outlook, automatic configuration is supported, so that when you set up your TUC e-mail account, you only need to enter your name, e-mail address (givenname.surname@unit.tu-chemnitz.de – see IdM portal) and password. All other details will be completed automatically.

Detailed instructions for e-mail programmes, devices and apps (in German)

We strongly advise against using “The new Outlook” (Windows 11) for your e-mail account at Chemnitz University of Technology, as your e-mail and access data are stored in the Microsoft cloud! We recommend Thunderbird.

E-mail program: Retrieving e-mails (inbox, incoming mail)

Recommended: IMAP via TLS/SSL encryption

• IMAP protocol – supported by all modern e-mail programs:
  • Management of e-mails in folders and shared mailboxes
  • Same view from different e-mail programs and Webmail
• Encrypted data traffic
• Server name:mail.tu-chemnitz.de
  Encryption: TLS or STARTTLS (or SSL)
  Authentication with URZ username + password – recommendation: App and device password
  or via Kerberos5/GSSAPI

E-mail program: Sending e-mails (outgoing mail)

SMTP via TLS/SSL encryption

• Server name: mail.tu-chemnitz.de
  Port 587, with authentication (URZ username + passwort) – recommendation: App and device password
  Encryption: TLS or STARTTLS required
• If problems occur when sending, please check that a virus checker is not monitoring outgoing mails. Unfortunately, this function is often error-prone and must be switched off in the event of an error.
• Troubleshooting for sending e-mails via Telekom-DSL (in German)

Processing e-mail without an own mail program

HTTPS

• Webmail – easy access to the mailbox from any web browser (realised with SOGo). This is especially interesting for new users (simple, no configuration) or from home and on business trips. This works also from the Internet without VPN mit Multi-factor Authentication (MFA).
• Access via https://mail.tu-chemnitz.de/

Via Remote Login – Secure Shell (ssh)

By logging on to the URZ login server, you can use an e-mail programme installed there, e.g. the alpine program.

• Use a Secure Shell Program (ssh, putty): Server name login.tu-chemnitz.de (VPN required)
