Using the New Outlook for Mac features in business environments
Dear @Anthony,
I hope you’re having a good day.
I tested this in New Outlook for Mac and was able to reproduce similar behavior. When a SharePoint or OneDrive sharing link is pasted directly into the message body, Outlook automatically converts it into a Microsoft 365 shareable link and may replace the visible URL with a shortened or friendly display name. This is documented behavior in Outlook's Shareable Links functionality.
As a workaround, you could try using Attach file >** Insert **Hyperlink instead of pasting the URL directly. In my testing, I was able to place the full SharePoint URL in the Display as field, which preserved the complete visible URL for recipients. The link remains clickable, but users can see the full address before accessing it.
According to Microsoft's documentation, this behavior is intended to improve sharing of OneDrive and SharePoint content by creating shareable links, validating access permissions, and helping ensure recipients can access the linked resource.
Based on my research, I have not found a documented setting in New Outlook for Mac that forces SharePoint or OneDrive links to remain as plain text by default. Given your security-focused use case, submitting feedback through Help > Feedback in Outlook may be worthwhile as this appears to be a product design request rather than a configuration issue.
I hope this information helps point you in the right direction. If you run into any issues while trying the steps, or if something still doesn’t feel quite right, please don’t hesitate to reach out again. I’ll do my best to support you however I can.
Looking forward to hearing back from you with any updates or additional details.
