I have had outlook 365 for years. Nothing on my end has changed. Suddenly (as of yesterday) every time i click on New Email a pop out window opens up (and the signature within my email is HUGE. About a 48 font yet the font showing is 12) This has never happened before and it is QUITE annoying. I have searched within the OPTIONS of Outlook and I cannot find anything with the option to open a pop out window when composing a new email. So there appears to be nothing for me to check/uncheck in this regard. As far as I know i have had no updates to Outlook that would have made this happen. Has anyone else had this happen and have you figured out how to stop it?????

I too am having this issue. When I use my mouse or keyboard to open an email, then it opens in the same browser tab. BUT when I touch an email to open it, then it opens in a pop-up window. Very inconsistent and frustrating.
Yes, one day about two weeks ago, new windows started opening when I touched the screen. I can't stop it. It used to just open the email without a new window popping out. This SUCKS and I hate it. But I can't figure out how to stop it. HELP!
This started on my email. I don't like my emails to pop out! I have tried all the suggestions here. I don't want a reading pane either. I use outlook web.
I had the same issues, the box was unticked. However, I ticked it and now the extra reading pane is gone.
I was having the same issue but I found the solution. On the View tab go to Layout > reading pane and select bottom.
The View worked for me as well - changed it from Reading Pane - Right to Reading Pane Bottom - then switched it back to "right" and it stopped opening emails as I clicked on them.
