Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Jspin77,
May I know which Office 365 desktop client channel version are you using please provide us with the detailed information about this, see About Office: What version of Office am I using?
Since you mentioned "maybe it was because I temporarily hooked my laptop up to a different monitor", have you tried to restart your laptop to check this issue?
You may check whether you have Turned on Touch Mode. If so, tap the Touch/Mouse Mode hand icon on the Quick Access Toolbar and tap Mouse to see if there any difference.
Note: If you don’t see the button or the icon on the Quick Access Toolbar, Press, hold, then release any button on the Quick Access Toolbar, then tap Customize Quick Access Toolbar. Under Popular commands, tap Touch/Mouse Mode, and tap Add.
Moreover, please provide us with detailed screenshots about the issue so that we can check to further assist you.
Your cooperation is highly appreciated.
Best regards,
Shyamal
