# Importing Certificates in Outlook

This source provides a technical step-by-step guide for importing user certificates and private keys into Microsoft Outlook to enable secure email communication via S/MIME.

## Key Instructions
- **Import Path:** `File` $\rightarrow$ `Options` $\rightarrow$ `Trust Center` $\rightarrow$ `Email Security`.
- **File Formats:** Supports `.p12` and `.pfx` files.
- **Security Recommendations:** 
    - Use a password to protect the private key.
    - Select **SHA256** as the hash algorithm for the security object.
- **Functionality:**
    - **Digital Signatures:** Can be automated by enabling "Add digital signature to outgoing messages".
    - **Encryption:** Must be selected manually per email via `Options` $\rightarrow$ `Encrypt` during composition.

The guide is provided by the [[universitatsrechenzentrum-urz]] and references the [[groupware]] ticket system for support.
