Can't resize Word or Excel windows

Try a restart.

Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

Isolating an issue by using another user account

If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Hi,

I have (still) the same problem. Excel won't resize after opened a file. The funy part is that I notice the files with problem was saved in LibreOffice in a Windows 10 machine. The rest of files opens normaly.

System: MzcBook - El Capitan 10.11.3

Excel 2015 v. 15.18

Any clue/solution ?

After some workaroung did click the protect/unprotect and the rezise starts to work.

Don't ask me how/why.

Thanks, after several tries the resizing works.

Thank you!

Just had this problem with my CV and found your solution.

Whew.

Thank you so much Joy. My computer just auto-installed an OS X update and my MSWord windows had the same problem. Yours was the first thing I found when searching for a resolution and yours worked!!! It pays to take time to post this kind of thing for here I am, almost 2 years later, and you solved my issue! 😁

Thank you!!!!!!!!!!!!!! 🙂

This solution still works. I just updated MS Office and this issue seems to happen every time after an update.

Thanks for posting the problem and solving it. The solution still works!!

OS X Yosemite 10.10.5

Word 2008 12.1.6

Thank you! I had the same problem after the system updating. Changed the resolution and it opens in the ordinary size now, and the screen is easier to read as it's bigger.
