I have office 365 installed on my home PC and laptop. I pay Microsoft every month for the licence. However my work account allows me to install office on my own devices so I don't need to pay for something I am already entitled to. Is there a way I can switch between the two without having to do an uninstall/reinstall?

  • Is the work version also an online-activated version like Office 365 Business? – Daniel B Sep 17 '15 at 9:27
  • It says MS Office 365 ProPlus Subscription Product on the Account page in Word - that's my work version – Rob Sedgwick Sep 17 '15 at 9:36

    Office 365 activation is based on what Microsoft Account you are logged into. If you work will allow you to log into their Office 365 account they have assigned for your use, you can do so, easily enough. You obviously would need to install the same version of Office 365 in order to do so. – Ramhound Sep 17 '15 at 15:03

Yes you can do this. If you O365 account is enabled with the license. Simply sign out of your existing office and then sign in with your work account.

  1. Open a single Office App (Word, Excel, etc) and close the others.
  2. Click File to go to Stage area
  3. Click "Account' in left hand menu
  4. Under "User Information" click Sign Out.
  5. Restart the application then sign in with your work account.

There is a "switch account" option there - You can try that, but I have 100% success with the above method.

Now on your personal account you may want to sign into O365 and deactivate the license. If you are using the personal O365 subscription keep in mind that this also grants you storage for OneDrive personal and Skype minutes. If you use those don't cancel the subscription. If you don't - and all you used was Office, than it's probably worth canceling as you won't be using that feature.

Unfortunately, no. The version from work is most likely a Volume Licensed edition, whereas your copy would fall into the retail stream. This means that you would need to reinstall and activate using the media and key your work provides

  • I believe the channel is not as important as the edition. His work account most likely offers Office Pro Plus, which he probably didn’t have before. – Daniel B Sep 17 '15 at 9:27
  • @DanielB true, but you have to admit that the channel is still important :P – td512 Sep 17 '15 at 9:34
  • With Office 365, if shouldn’t matter. The activation method is always the same. However, you probably can’t activate Office cross-edition, even when you have a “superior” edition licensed. – Daniel B Sep 17 '15 at 9:46
