When I type emails in Outlook.com, the font and point size changes midway through. My selected preference for outgoing messages is Verdana 10 point. Every time I write an email that is longer than one sentence, the font changes to Calibri 12 point at some random place. So, before I press Send, I need to highlight the entire email, select Verdana from the toolbar and then select 10 point from the toolbar. This is bothersome, particularly when I forget to make the change on outgoing business-related emails.

I would appreciate your help.
