Using New Outlook on Windows for professional communication and productivity
I didn't find a working fix easily, so here is what worked for me, just in case someone hasn't offered a working fix.
- Determine what 'Ribbon' layout you are in. (Mine was in the 'Simplified Ribbon' mode which hides the 'Zoom' button.)
- Open the email.
- Look for the down arrow at the right-hand side of the ribbon.
- Click the down arrow.
- Ensure you have the the 'Classic Ribbon' option selected.
- You should now see the 'Zoom' magnifying glass button.
- Click the 'Zoom' magnifying glass button.
- Change the 'Percent' to '100'
Hope this helps.
