I also have an Outlook error which appears to relate to latest update to Tahoe
Outlook font issues since Tahoe 26.5.1. upgrade
I’m using Outlook 16.110. Since the upgrade (yesterday) outlook is presenting difficulties with the fonts.
It is presenting in Bold (even though set to normal) will not change to - say italics - if I change to Aptos it sticks there and will not switch back to my default font.
I have tried a number of actions to resolve the problem:
resetting the cache using terminal
deleting the fonts and reinstalling
using the web (same problem)
The legacy version works OK but is not ideal
Any ideas much appreciated
