Maximizing Your JGU Mail Capabilities

Resolving Access Challenges with Your JGU Account

⚠️ Forgot JGU Account Password

Cause: Inability to recall your JGU account password, preventing access to mail and other services.

Solution: If you are a student or doctoral candidate, swiftly reset your password by visiting https://account.uni-mainz.de/password/init-reset. Enter your username and a private email address, then provide your matriculation or registration number for verification. You will receive a password reset link to your private email, valid for 60 minutes. Employees with a PUK can use https://account.uni-mainz.de/password/reset. If you're an employee without a PUK, you'll need to visit the Central Library's circulation desk with a photo ID and your JGU username to obtain one. Visiting scientists, project staff, or student assistants should contact their supervisor or a JGU account manager.

⚠️ Difficulty with Mobile Email Access

Cause: Problems setting up or using JGU email on a smartphone, often due to using unsupported applications.

Solution: We understand that being locked out can be stressful. The official Microsoft Outlook app is blocked for data protection reasons, as it routes data through external servers. Instead, use your mobile device's pre-installed email application and configure it as an Exchange account. Ensure you use the server mail.uni-mainz.de and port 443 with SSL/TLS enabled.

⚠️ Account Not Yet Active

Cause: New students unable to log in because their JGU account has not been activated.

Solution: As a new student, your JGU account requires activation after enrollment. Check the email address you registered during your application for an activation link, which typically arrives within 48 hours of enrollment. Follow this link to activate your account and establish your password.

Quick Answers to Your JGU Email Inquiries

Q: How can I access my JGU email?

You can access your JGU email through the webmail portal at https://mail.uni-mainz.de using any modern web browser. Alternatively, you can configure an email client such as Thunderbird, or your smartphone's pre-installed email app, as an Exchange account with the server mail.uni-mainz.de.

Q: Can I use the Microsoft Outlook app for my JGU email on my phone?

No, the official Microsoft Outlook app is explicitly blocked by Johannes Gutenberg University Mainz for data privacy reasons. This app routes email traffic and other data through Microsoft's servers abroad, which conflicts with JGU's privacy policies. It is strongly advised to use your device's pre-installed email app and set it up as an Exchange account instead.

Q: What should I do if I forget my JGU email password?

If you are a student or doctoral candidate, you can reset your password by visiting https://account.uni-mainz.de/password/init-reset. You will need your username, a private email address, and your matriculation or registration number for identification. A reset link will be sent to your private email. Employees should refer to specific procedures involving a PUK or contact the Central Library.

Q: Are there any limits on email attachments or recipients for JGU mail?

Yes, there are specific limits to ensure system stability and fair use. The maximum size for an email attachment is 24 MB. You can send emails to a maximum of 1000 recipients within a 24-hour period, and each individual email can have up to 200 recipients. For sending larger files, consider using Seafile to share split links.

Q: Is it possible to automatically forward my JGU emails to a different email address?

No, automatic forwarding of JGU emails to external email addresses is deactivated. This measure is in place to comply with data protection regulations and ensure the security of university communications.
