Window Size Problem with El Capitan

Thanks for this information -- however, this (I think) is only a fix for Office 2016 and moreover for those with an Office 365 Subscription. It isn't for earlier versions (e.g. Outlook for Mac 2011)...

Agree. For me Outlook 2016 was the only piece of software with this faulty behavior. At least it might lead to the conclusion that the problem is not OS-related but app-related.

I know this thread has been focusing primarily on windows size issues with Outlook on El Capitan, but I can confirm I'm having this same issue with Apple's own Calendar application. I've given them some "feedback" about it. I hope this gets resolved in 10.11.3.

I also have been getting finder window resize (windows are too small) issues since upgrading recently to El Capitan.

Same Problem.

Outlook resize windows while I scroll messages list.

Obviously I cheered to soon. Problems are back after a day or two. So again having the resize problem. Perceived even more often than before. Guess I am just annoyed 😟

I think I have found a potential "solution" to the resizing window issue. I had the exact same issue as the OP which lead me to this thread. Here is what I did to resolve the problem and I think this will work with all apps.

1. Open Outlook (or whatever app)
2. Resize the window to what you would like it to be as the default
3. CMD-Q to quit Outlook (or whatever app)
4. Re-open Outlook, and it should come up as the resized window size.

I hope this helps you guys out. It bugged me since I moved to El Capitan. I'm sure this is just a "feature". As Steve says, "it just works"

Perhaps I didn't do sufficient testing, but when I did the "solution" I described to set the default window size, hitting the ❌ circle for the outlook window, then opening up outlook again gives me the newly set window size. I'll keep playing with it, but in my limited testing, the outlook window hasn't reverted to the small window.

Corvairkid: Exactly right. Quit and reopen *always* works, Outlook's window opening in just he way you have previously set it. But closing the window (CMD-W) and then reopening (I used to cycle through open programmes using CMD-Tab and then hitting CMD-1 to reopen Outlook -- it was the work of a second or two and utterly instinctive) -- DOESN'T work. The ONLY option currently is to minimise the window to the dock.

It's such a tiny -- but supremely annoying -- thing...

I'm not sure why your windows are not behaving. I've been futzing with yesterday and today, and my outlook window stays the size that I set when I CMD-Q (quit) outlook. I can open and close outlook over and over again and it stays the size that I set it. I haven't had it revert back to its tiny window.

Sorry that it didn't work for you, but it worked for me. I haven't tried sleeping the computer or shutting down the computer, perhaps that it behaves differently when the computer sleeps?

The point is, davesnothere, that Outlook's windows *do* behave properly if you quit and relaunch. What they don't do is behave if you simply CMD-W close the window and then reopen. Hence all these folks complaining that go avoid quitting and relaunching they now have to keep Outlook minimised to the dock and zoom it open from there... Sorry, but this problem is almost harder to explain than it is to experience. If you just close the window and then reopen it, see how many times you can do that before the window shrinks to a size that is useless...

I have been hitting CMD-W to close and reopen my outlook window quite a bit and my window stays the same "corrected" size. I know what you guys are saying. I've been hitting the red x and CMD-W to close my outlook window. I would say that in the past hour, I've done it roughly 100 times, and it has never reverted back to the tiny window for me.

I'm not saying that you guys aren't experiencing the tiny window issue. I'm just saying that the solution I proposed worked for me. I'll just call it lucky.

It was annoying the heck out of me too thats why I found this thread to begin with. I was just trying to help out. If it doesn't work well for you, sorry about that. Good luck guys. Hope you guys find a solution that works for you.
