TUHH SOGo webmail storage is full, you will likely experience issues such as being unable to receive new emails or receiving "mailbox full" warnings. Since the SOGo server at TUHH
acts as a frontend for the central IMAP mail server, managing your storage requires cleaning up your mailbox directly. Technische Universität Hamburg Quick Fixes for a Full Mailbox Empty the Trash and Spam Folders
: Deleted messages are moved to the "Trash" folder but still count toward your quota until permanently deleted. Right-click these folders in the SOGo Web Interface and select "Empty" to free up space immediately. Remove Large Attachments : The maximum message size is approximately tuhh webmail sogo full
. Look for older emails with large attachments and delete them or save the attachments locally before deleting the email. Clean Up "Sent" Folder
: TUHH mail clients typically save outgoing mail in a folder named "Sent". Periodically clearing this folder can significantly reduce storage usage. Technische Universität Hamburg Technical Support
If you have cleared your mailbox but still receive "full" errors, it may be due to hidden folders like "Recoverable Items" that are not visible in the web interface.

The SOGo system at the Hamburg University of Technology (TUHH) is the central groupware solution for managing emails, calendars, and contacts. It is not an independent email server but acts as a web-based interface that accesses the university's central IMAP servers. Core Functionalities
Email Management: Provides a web interface for your @tuhh.de account. It uses IMAP to view and manage emails stored on the TUHH central mail server. Calendar Services: Automatically creates a personal calendar for every user. The "Full" version is where SOGO shines
Allows for the creation of multiple private or shared calendars.
Includes subscriptions for German public holidays and regional school holidays (Hamburg, SH, Lower Saxony).
Address Books: Synchronizes with the RZT-provided global address books and supports personal contact lists.
Task Management: Built-in task tracking that integrates with the calendar.
Access Requirements: Use of the SOGo service requires an active TUHH account with an assigned @tuhh.de email address. Setup and Integration Direct Access: Log in via the official SOGo portal. Disclaimer: URLs and specific server settings are subject
Client Synchronization: You can sync SOGo data (calendars/contacts) with external clients like Thunderbird or mobile devices using CalDAV and CardDAV protocols.
Group Permissions: University organizational units (OUs) are mapped as groups within SOGo, simplifying the process of sharing calendars or assigning permissions to specific teams. Important Constraints
Not a Mail Server: SOGo is purely a frontend; if the central mail server is down, SOGo cannot display emails.
Storage Limits: Your email quota is determined by your TUHH mail account settings, not by SOGo itself. Webmail/Kalender (SOGo) | RZT - TUHH
Modern universities require reliable, scalable, and secure communication platforms. TUHH adopted SOGo – an open-source groupware solution – to replace or supplement legacy email systems. The “SOGo Full” interface provides native webmail access, calendar sharing, contact management, and task handling. This paper explores how TUHH customizes and deploys SOGo to meet academic and administrative needs.
