Why Does Outlook Do This?

In Outlook Professional (or MS Office Professional?), when I reply to an email, the email opens to the far right (mostly off the screen). I have to click on “Pop Out”, an annoying and useless feature. For what purpose or to what benefit does this possibly have to justify why Outlook does this? Can I change some option / some setting to stop this? It should just open like normal and let me type my reply! Grrrr…

This is odd and shouldn’t happen. You can try going to Options…Mail…Replies and Forwards. Check “Open replies and forwards in a new window”.

What version of Outlook is this?

Strange. Do you mean it opens farther to the right of the message panel? Because when I reply it opens in the message panel (and I’ll Pop out if I want to see the message in more detail while replying to it).

If something is mostly off the screen that’s a clue that your screen size & resolution are not what Windows thinks they are. That can happen if you have a laptop that sometimes has a second screen plugged in and sometimes doesn’t. Or if you change screen resolutions.

First off make sure your Outlook window isn’t bigger than your current screen size. If you can’t see the dash, the two overlapping squares, and the X that are in the upper right corner of every Windows window you’ve ever seen, that’s your problem. Those are hiding somewhere in space out to the right of your screen. If so, you need to shrink the Outlook window. Grab the left edge and drag it some ways towards the right to make the window narrower. Then grab the top title bar and drag the whole window to the left. Repeat as necessary until you can see both the left and the right edges of the main Outlook window.
Do the same thing vertically. Drag the top down then the window up (or vice versa) until you can see all 4 corners of the main Outlook window on the screen.

Then quit Outlook. That will save that smaller size as the default for the future. Then reopen Outlook. It should re-appear in the same size and place and you can still see all 4 corners. Now either drag the edges around to be whatever size & placement you really want to use, or click the single square at the upper right corner to have it fill the screen; whichever you prefer.

Quit Outlook again and re-open it. From now on it’ll be the right size.

Note there’s nothing Outlook-specific about the advice above; it applies to any Windows program that you’ve inadvertently made bigger than the screen.

Dagnabbit. I never thought about looking for a setting. I’m doing this on Monday.

Don’t care that my work computer is in the next room. I’m waiting until Monday. Did send myself an email though.

It is the default behavior on installation for Office 365 and 2019. I am not sure about prior versions.

Sorry, I meant the window sliding off screen shouldn’t happen, not pop-up vs new window.

Do what I do: Turn of the “reading pane” feature.

That must be it. Let me look into this and see if this doesn’t solve the problem.
