Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
From my experience, this can be done but you need to set the Font of each application separately.
For Word, choose the Font selection (click on the arrow at the bottom right of Font area) then choose your desired Font, Size etc. and choose "Set as Default". Make your choice on the prompt if you want to change it only for this document or for all documents under Normal.dot template.
In Outlook you need to go to File - Option - Mail - Stationery and Fonts - New Mail area - Font button.
Make your Font selections. Click Ok.
Repeat the same for Replies.
