Exploring the University Email Communication Tools

Resolving Common UDE Email Access Challenges

⚠️ Cannot log in (message: 'Sie müssen angemeldet sein um Zugriff auf diese Seite zu bekommen.')

Cause: Browser session or cache issue.

Solution: We know being locked out is stressful. The quickest fix is to restart your web browser. If the issue persists, try clearing your browser's cache and cookies specifically for the UDE webmail site. This often resolves temporary login glitches by removing outdated session data.

⚠️ Forgot Password

Cause: User cannot recall their password for their University ID.

Solution: If you've forgotten your password, you can easily reset it through the Selfcare-Portal. Alternatively, you can seek assistance at one of the university's e-Points. It's important to note that after a password change, it may take up to 20 minutes for the new password to synchronize across all systems, like the Exchange server or Active Directory. To prevent temporary account locking, make sure to log out from all PCs or virtual machines that use your University ID for authentication *before* changing your password.

⚠️ Mailbox is full / Over Quota

Cause: Your email storage limit has been reached.

Solution: When your mailbox reaches its maximum capacity, incoming emails will be rejected. To fix this, you need to check your current quota and delete unnecessary messages or large attachments to free up space. Regularly managing your stored emails will prevent this issue.

⚠️ Account blocked due to spam distribution

Cause: Violation of email sending guidelines (e.g., sending too many emails or to too many recipients).

Solution: The university implements strict user guidelines to combat spam and protect the network. If your account is blocked because of these rules, you will receive a notification explaining the reason. If you have a legitimate need to send a high volume of emails, please contact the ZIM Hotline or an e-Point to discuss potential exceptions for your specific mail procedures.

⚠️ Emails with old Microsoft Office formats (.xls, .doc, .ppt) are not delivered

Cause: Security measure against malware.

Solution: Since July 1, 2019, UDE mail servers reject emails containing attachments in older Microsoft Office formats like .xls, .doc, or .ppt because they are frequently used to spread malware. To ensure your attachments are delivered, always use newer formats such as .xlsx, .docx, or .pptx.

⚠️ Sending emails with TLS certificates fails when using antivirus software

Cause: Antivirus software interfering with TLS encryption.

Solution: If you are using antivirus software like Symantec, Norton Antivirus, or McAfee VirusScan and experience issues sending emails with TLS certificates, you may need to temporarily turn off the virus checks for outgoing emails within your antivirus settings. This often resolves conflicts with secure email transmission.

If you've forgotten your UDE mail password, you can easily reset it using the Selfcare-Portal. Alternatively, visit one of the university's e-Points for assistance. Remember that it might take up to 20 minutes for your new password to become active across all systems, and it's best to log out of all active sessions before initiating a password change.

However, please avoid using the newer Outlook app for Windows, iOS, and Android for official university purposes due to security concerns regarding password synchronization.

The University of Duisburg-Essen employs robust security measures, including automatic spam protection and malware scanning through a Pre-Queue-Filter. Emails identified with viruses or executable attachments are automatically rejected.

Q: Is it possible to forward my UDE emails to a different personal email address?
