The Office Suite is powerful enough to support both Windows 10 and Mac users, but that does not mean that it does not come with its fair share of problems.

A while ago, Microsoft had released an official web page with the most known issues concerning Office and Windows 10 and has provided a couple of fixes for the aforementioned.

We’ve decided to add some more to the list. So without further ado, here are some useful methods to solve Microsoft Office 365 known issues.

When typing in any sort place where typing is desired, using Google Chrome, Microsoft Internet Explorer or Microsoft edge, I have a problem with typing a t causing a new tab, typing an i causing shift to italics. It’s as if I am typing a ctrl-t when I am not. Unasked for shift to a new tab is chronic no matter what platform I am typing in. It makes use of the computer almost impossible. WHat is causng this? BTW, it happened 12 times while typing this note.

Tried installing a cracked MS Office, it crashes. Tried installing legit MS Office, still crashes. I tried that desktop stand-alone OneNote (just so i can save my work stuff), thankfully i got to use it so i can export to Evernote; then after that, it crashed also. Dell laptop here. This isn’t the first time this has happened, but then when it did, i reformatted. I don’t wanna reformat this time. I will lose all the modifications i did on my unit. trying how reimage software can help. hope this isn’t the thing that asks for money after scanning and holds my unit’s security hostage until i feed it $$$

PS. welp. As expected.

I purchased a new Win 10 laptop, installed Professional plus 2016 and then the system crashed within a week with every key I typed repeating until I pressed another one. THis meant I couldn’t log in. Am not 100% certain that the Pro Plus was too big for the laptop (Intel Atom x5-z8300 cpu 1.44ghz 2GB RAM 32-bit os and x64 based processor. With refreshed laptop, what office setup should I go with?

Windows 10, Office 2016, new Dell laptop. When typing in Word, cursor disappears and entire system freezes. Control-alt-delete doesn’t work. The only way to fix is to use the power button to turn off the computer, and then turn it on again. Does anyone else have this issue?

Me too, I thought it was a languages problem (Japanese system changed to English with English Office 2016), but if others are having the same problem…

i installed microsoft 2016 and i have windows 10
it works perfectly and i have done a report on word and saved it but when i reopen it, it messes up most of diagrammes and shapes
do you have any solution for this?

I installed Microsoft Office 365/2016. When I login my account to Word 2016 app, it started to crash every time I click on File Tab. Can anyone help me with this issue. Am running Windows 10 on Acer laptop. It works fine in the past in Windows 7.

That does not work. Having the same issue. Same issue with Excel. Upon opening Task Manager, either program is still showing as running, though they were closed down due to the error.

I have Windows 10 and downloaded Microsoft Office 2016. All my programs open except Word. Whenever I try and open Word it comes up that it is broken and I need to repair it in the control panel. This I above my knowledge base.. Can anyone tell me what the issue is and how I can fix it?? Kind of frustrated.
