Overview of the email servers and their use

The Heidelberg University Computing Centre operates different email servers to cater for the user's varying requirements. Here is a list of the possible addresses you may receive from the URZ or your institute:

User type Email address Server
Students <name/uni-id>@stud.uni-heidelberg.de imap.urz.uni-heidelberg.de
Employees <name/id>@uni-heidelberg.de imap.urz.uni-heidelberg.de, exchange.uni-heidelberg.de
Institute employees with own domain <name/id>@<institute-abbreviation>.uni-heidelberg.de imap.urz.uni-heidelberg.de, exchange.uni-heidelberg.de

Incoming mail server settings (IMAP)

User name: Uni-ID

Mailboxes are created on the imap.urz.uni-heidelberg.de server by default.

You can access your mailbox both via an email client and using a web interface. Alongside email access, this provides an address book and a calendar function. All functions are also available via Active Sync. The necessary data for the different servers is as follows:
