Hi @Christin
Thank you for posting your question in the Q&A Forum.
It appears that the recent updates in New Outlook for Mac have updated how signatures from previous versions are rendered, which can occasionally affect line spacing and cause text duplication.
To ensure your signature displays with consistent single spacing and to remove any redundant text, we recommend a quick refresh of your signature settings:
- Refresh the Formatting: Copy your current signature and paste it into TextEdit (set to Format > Make Plain Text) to strip away any outdated HTML tags. Then, copy and paste this clean text back into your Outlook Signature settings.
- Use Soft Returns: When re-formatting, use Shift + Return instead of just Return. This creates a single line break, preventing the app from defaulting to 1.5 paragraph spacing.
- Clear Duplicates: If you continue to see duplicated lines, try removing the signature entirely from your settings, restart Outlook, and then add the refreshed version again.
Please feel free to update the thread and let us know if these adjustments help with the spacing.
