How to change my mobile Outlook font back to calibri?

I had to create a new signature within my desktop app following the instructions given by Robert Quirk1 by going to File > Options > Mail > Create or modify signatures to messages.

Then create a new signature (I named mine Hi for simplicity sake).

Write Hi then hit return a couple of times and write however you want to end the message - make sure its in the font and size you desire.

Click save.

Under 'Choose default signature', select this newly created signature (Hi) for your new messages and replies/forwards.

Click OK.

Now go to the mobile app and go to Settings.

Select Email signature and check that it's selected to 'Use my signature from Outlook on the web'

Then close the app.

Reopen app. Now hopefully it should work. Create a new message, start writing after Hi.

After composing your message you can delete the extra lines before the Hi.

I'm using the Android app and this signature workaround only worked after I created the signature on the desktop app.

Agree 100%. Have tons of business templates in Calibri, and now our phones default to Aptos. There should be an option to modify phone fonts.

I'm absolutely shocked that this issue hasn't been resolved, especially since it has been almost a year! I really dislike aptos font in my Outlook app. I've noticed that many others have reported the same issue, yet nothing has changed. This reflects poorly on Microsoft 365's customer service.

Dear Microsoft,

This is really disappointing, Kindly enable user to change font for Mobile Outlook apps.

BR,

Has anyone received an update yet? When do we get rid of Aptos and have Calibri back on outlook mobile app? It was supposed to be complete by early Oct 2024, right? I still have aptos on my phone and there's no obvious way to change it back to calibri? Does anyone know when & how it happens? thanks.
