Dear Tarryn,
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
To add an HTML signature to Outlook for Mac, you need to follow these steps:
- Open Outlook and go to the "Outlook" menu at the top of the screen.
- Select "Preferences" and then "Signatures".
- Click the "+" button to create a new signature.
- Give your signature a name and then paste the HTML code into the text box.
- Click "OK" to save your new signature.
If the HTML code is not displaying correctly, you may need to make sure that it is formatted correctly. You can use an HTML editor to check the code and make sure that it is valid. Additionally, make sure that any images or links in the signature are hosted on a public server and are accessible to anyone who receives your emails.
I hope this helps! If the issue persists, please comprehend that the HIML related issue is having something to do with deveopment, which is out of our support scope, we have limited resource and knowlege on development related issue, in this situation, we suggest post your query on Office Development - Microsoft Q&A. Engineers who are dedicated into this environment with rich experience and more resources can then assist efficiently. We believe they would conduct in-depth research on the problem you encountered and provide you with more professional assistance.
In the meantime, I would also like to invite community members and MVPs in the forum to share their knowledge or any workaround and insight on this topic.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
Sincerely,
Sherry | Microsoft Community Moderator
