These problems can occur in any or all of the Office products such as Word, Excel, Access, Powerpoint, Publisher, OneNote, Outlook, Infopath or Lync; by displaying one of the following messages (or similar)

“Unlicensed Product”

“Product Deactivated”

“We’re sorry, something went wrong and we can’t do this for you right now. Please try again later”

or similar.

You can re-activate Office 365 or Office 2013  in a number of ways as follows

1) Repair Office 365 or Office 2013

In Windows 7 or 8 locate “Control Panel” > “Programs” > “Programs and Features”

Highlight “Office 365 ProPlus” (do not click on it) and select the “Change” button

Select “Quick Repair“. When it is finished you’ll see this image:

Once that appears, click to Close it out and try to open your MS Office product once again. When I did it, it didn’t work the first time. I had to open it and close it then open it again. If it doesn’t work still, try restarting your PC and trying again.

If this does not fix your problems try “Online Repair” next. If it still doesn’t work, reinstall Microsoft Office 365 with the following instructions:

Reinstall Office 365 or Office 2013

From any of the office products click on the left arrow in the top left of the product, then click on “Office Account”

Click on “Manage Account” to login to your Office 365  or Office 2013 account

Once signed in, navigate to “software”

Then click on “Install“. This will downlaod a file that needs to be executed by clicking on it. This will start the “Office 365 reinstall”
