# Outlook Central Address Book Configuration

The integration of the [[zentrales-adressbuch]] into [[microsoft-outlook]] allows users to query university employee contact data directly from their email client using the Lightweight Directory Access Protocol (LDAP).

## Technical Requirements
To establish a successful connection, the following parameters must be configured in the Outlook LDAP settings:

- **Server:** `adressbuch.uni-greifswald.de`
- **Port:** `636`
- **Encryption:** SSL/TLS must be enabled. The system requires ciphers starting from **AES 256**.
- **Protocol:** LDAP v3.
- **Authentication:** No login credentials are required for this directory service.

## Search Configuration (Base DN)
A critical component of the configuration is the **Base DN** (Distinguished Name), which defines the starting point for the LDAP search. For the university directory, the following custom value must be used:

`dc=uni-greifswald,dc=de,dc=TLD`

## Operational Note
After completing the configuration wizard in Outlook, a **full restart of the application** is mandatory before the central address book becomes available for use.
