Why has Microsoft forced a change on typeface in Outlook for desktop?

In my case the problem is in the Classic Outlook Contacts/address book. My custom default font Verdana 10 pt has been changed to Aptos 12 pt for existing contacts, something I noticed when recently installing M365 on my new Windows 11 computer, having been on Win 10. I have checked the default settings; they are all on Verdana 10 pt barring the signature, which is on 9 pt. My entries were mostly on Verdana 10 pt, with some on 9 pt.
New entries are in the correct font.

How do I force a reversion to what the fonts were on all my existing contacts?

BTW, Aptos is NOT an improvement over Calibri or Arial as claimed. It still fails to distinguish between I (capital 'eye') and lower case l ('ell'). Good examples are the German city of Illertissen...and "Illness" in English. (Yes, one can guess which is which here, but it is not always that simple.)

Hence my preference for Verdana for 'normal' typing and Tahoma where a narrower typeface is desirable. On top of that, both have been widely available on many platforms for decades. (Can't demonstrate the difference here because the typeface is fixed - try it at home...)

I had earlier posted the question in this, related thread:

    Hi @Dori A Schmetterling

    I understand your frustration, especially since your existing contacts were previously formatted consistently in Verdana.

    Aptos became the default font across Microsoft Office as part of the newer Office theme. However, the font settings under File > Options > Mail > Stationery and Fonts mainly apply to email composition and newly created content. They do not automatically restore or reformat text already saved in existing contact records. This may explain why new contacts use Verdana correctly while older contacts appear in Aptos.

    Unfortunately, Classic Outlook does not currently provide a supported option to change the font in all existing contact notes at once. As a workaround, each affected contact would need to be updated individually:

    • Open People and select an affected contact.
    • Select Edit Contact.
    • In the notes section, press Ctrl+A.
    • On the Format Text tab, select Verdana, 10 pt.
    • Select Save & Close.

    I recommend testing this with one contact first. If the contact returns to Aptos after reopening Outlook, please share your Outlook version and build number from File > Office Account > About Outlook, as this could indicate a rendering or migration issue rather than a permanent change to the stored formatting.

    You can also report this through Outlook > Help > Feedback, since there is currently no bulk reformatting control for existing contacts.
