Welcome to the official guide for TU Dortmund Webmail, the essential digital communication platform for all university members. Known as UniMail, this service provides every student and employee with a dedicated email address and mailbox, facilitating crucial academic and administrative correspondence. This guide will help you navigate your UniMail portal with ease, ensuring you stay connected to all important university updates and personal communications. UniMail is powered by your central UniAccount, which acts as your single digital identity across various TU Dortmund services. Whether you're accessing course materials, managing your student records, or collaborating with colleagues, your UniMail account is a cornerstone of your digital experience at the university. Understanding its features and how to use it securely is vital for a smooth and productive interaction. This resource provides accurate, up-to-date information directly from the university's IT and Media Centre (ITMC). We aim to equip you with the knowledge to efficiently manage your online account, resolve potential issues, and maintain the security of your digital workspace, all while adhering to the university's robust standards.

Unlocking UniMail's Full Potential: Key Tools

Restoring Your UniMail Access: Solutions

⚠️ Cannot log in, receiving 'incorrect credentials' error

Cause: Browser not accepting cookies, or genuinely incorrect credentials.

Solution: First, verify that your web browser is configured to accept cookies, as this is essential for the webmailer. If the issue persists, double-check your UniAccount username and password. Remember to use your UniAccount identifier, not your full email address. If you're certain your credentials are correct, or you suspect a forgotten password, proceed to the 'Forgotten Password' solution below.

⚠️ Forgotten UniAccount password

Cause: User cannot recall their UniAccount password.

Solution: We know being locked out is stressful. For security reasons, the ITMC Service Desk cannot provide passwords via phone or email. To reset your UniAccount password, you must personally visit the ITMC Service Desk. Bring a valid photo ID (and, if you're a student, your enrollment certificate) to verify your identity. This is the fastest and most secure way to regain access.

⚠️ Mail not sending due to large attachments

Cause: Email server restrictions on attachment size.

Solution: If your email includes large files that exceed the server's limit, consider using the Sciebo service as an alternative. You can upload your file to Sciebo and then send a notification email with a download link to your recipients. Contact the ITMC Service Desk if this solution isn't suitable for your specific needs.

⚠️ Outlook (2013+) IMAP account not displaying all mail folders

Cause: Missing root folder path configuration in Outlook.

Solution: For Microsoft Outlook 2013 and newer versions, if you only see the top level of your inbox or experience sync issues, you may need to manually configure the root folder path in your account's advanced settings. This field is often blank by default but becomes necessary for proper display.
