Install your signature in Outlook

Outlook comes in several flavors. Steps differ by version.

Outlook for Windows (classic)

1. Click Install / copy in MailManagers.
2. Click Download HTML (.htm file).
3. Open the file in a text editor or browser and copy all content.
4. In Outlook: File → Options → Mail → Signatures.
5. Click New, name the signature.
6. Paste in the editor.
7. Right side: set which signature is the default for new mails and replies.
8. Click OK.

Outlook web (outlook.com / Microsoft 365)

1. Install / copy in MailManagers → copy the preview block.
2. In Outlook web: gear icon top-right → View all Outlook settings.
3. Mail → Compose and reply → Email signature.
4. Paste, name your signature.
5. Choose if it auto-attaches to new mails and/or replies.
6. Save.

Outlook for Mac

Similar to Windows: Outlook → Preferences → Signatures → click + → paste and save.

Known issue: borders

Outlook desktop sometimes strips inline CSS from signatures, causing unintended table borders. MailManagers generates HTML with double safety mechanisms (border="0" HTML attribute + inline CSS) to prevent this.
