Hi @Michael Moulton
Thank you for reaching out to the Microsoft Q&A forum
I understand how frustrating and inconvenient it can be when the line spacing formatting function is missing in Outlook for Mac, especially since it's such an essential feature for composing emails.
Based on my testing environment (Outlook for Mac version 16.99.1), I can confirm that the line spacing, or paragraph formatting options are not visible, just as shown in the image you provided. From my research, other users have reported the same issue and have raised it on the Microsoft Feedback Portal. To help bring this to the attention of our developers, I recommend either posting a new entry describing your experience or upvoting an existing one.
In the meantime, here are a few workarounds that may help:
Option 1: Use Outlook on the Web
Outlook Web App includes paragraph spacing options, which can be a helpful alternative for composing emails with more formatting control.
Option 2: Use macOS Paragraph Settings
You can format your email content using macOS's built-in paragraph settings:
+Select the email body content you want to format
+Right-click > Paragraph > Adjust spacing as needed
Optionally, you can select Set as Default to apply the paragraph settings to future emails automatically
Option 3: Revert to a compatible Outlook on MAC version
If possible, please consider reverting to a previous version of Outlook for Mac that is compatible with your macOS and still includes the formatting features you need. You can download earlier versions from the official Microsoft Learn page: Update history for Office for Mac - Office release notes | Microsoft Learn
