The text in my Outlook Reading Pane has increased in size and become double-spaced overnight. I have tried to change this with "Stationery & Fonts" and the View Settings without any success.
I have found the solution. I noticed an option named "Immersive Reader" was selected in the View Tab and switched it off - problem solved. I don't know how this was selected but it must have been a slip of the mouse. Sorry for any inconvenience caused.
