To add a shared mailbox in Outlook, open your Outlook client and then click "Tools" in the top menu bar. From there, select "Accounts..."

Next, click the “+” icon to add a new account.

During setup, enter the email address of the shared mailbox. Click “Next” to select the provider.

After clicking “Next,” click “Select Service Provider” and choose “Exchange.” 

You can then configure the shared mailbox. The email address of the shared mailbox should appear under “Email Address.” Under “Username,” enter the username for your primary account using the following format: [Your ZIMT username]@uni-siegen.de (e.g., g123456@uni-siegen.de)

Enter the ZIMT password for your primary account.

For the incoming and outgoing mail servers, enter“mail.uni-siegen.de.”
Finally, confirm by clicking “Add Account.”

Once the configuration is complete, a confirmation screen will appear. Click “Done” to finish.

Alternatively, you can also add a shared mailbox using the out-of-office feature in Outlook. To do this, open your Outlook client and then select the“Tools” menu item in the top menu bar. From there, select the“Accounts…” option.

Now, under "Accounts," open the advanced settings by clicking the "Advanced..." button. 

In the next window, open the “Out-of-Office” tab and click the “+” icon under “Also open these mailboxes.” 

Next, enter the email address of the shared mailbox in the search bar and select the corresponding entry. Confirm by clicking "Add" and save your changes in the previous window by clicking "OK."

Now select the service provider. For shared mailboxes, you must select IMAP/POP here. To do this, select “Other Provider.”

In the next step, you must configure the mailbox. To do this, enter the username using the following format: [Your own account username]@uni-siegen.de\[Shared mailbox alias] (e.g., g123456@uni-siegen.de\shared-test).
Also enter the servers for incoming and outgoing email. For both, this is mail.uni-siegen.de. Confirm again by clicking “Sign In.”

It will take a moment for the mailbox to be added. Then specify which items should be synchronized. Complete the process by clicking “Done.”

Before you can send emails, you’ll need to adjust a few settings on the account. To do this, open the account settings by going to Settings via the menu bar again and selecting the “Accounts” option. Then select the shared mailbox account and open the server settings. Here, you must make the following changes: 

• Uncheck the boxes next to “Manage connection settings automatically” under the incoming mail server and under the outgoing mail server. 
• Check the user IDs for both servers. For the incoming server, the format must be: [Your own account username]@uni-siegen.de\[Shared Mailbox alias] (e.g., g123456@uni-siegen.de\shared-test). For the outgoing server, enter only your own Nutzerkennung@uni-siegen.de (e.g., g123456@uni-siegen.de). 
• If necessary, specify the appropriate ports. The port for the incoming server is 993, and for the outgoing server, 587. Also, select “Use TLS/SSL” for both. 
• For the authentication method, select “Password” for both servers. 

Once these settings have been applied, you can now send emails from the shared mailbox as well.
