How to change my mobile Outlook font back to calibri?

Yes, just replace Calibri with every time I used Aptos. Calibri should be available on your desktop Outlook:

WORKAROUND:

1. Send an email from your Outlook desktop with some sample text formatted with the font of your choice to your Outlook mobile. I suggest this text be the name and size of the font you want your email to have. Example "Calibri****11".
2. Create an automatic signature in Outlook mobile.
3. Copy and paste the email contents you sent yourself into the signature.
4. Whenever you compose an email in Outlook mobile, start your email right after the formatted text. In the example below, you would start typing after "Calibri 11". Your new email text will now be formatted the same as the sample text.
5. Delete the sample text ("Calibri 11") after you compose your email.
6. Here's an example of the signature. You of course don't have to have a full signature like this, but must at least have the sample text "Calibri 11" formatted from Outlook desktop:

Dissapointing to know that we can't change the font size while replying from phone.

Poor and needs an answer or an alternative supplier asap

Microsoft needs to change this asap, and make this customisable. Aptos 12 is not appropriate. This is extremely disappoiting.

For all reasons offered above, really disappointing. Aptos 12 is unprofessional in appearance, and borders on amateurish. Balance of business owner clients share this view, and makes me wonder to whom the change is really tailored. Hopeful an alternative is soon available.
