If you are getting the error message "sorry another account from your organization is already signed in on this computer" when trying to sign into office please do the following:
(I am using MS Word in this example although you should be able to do the same steps in any of the MS Office suite products)
From an opened document click on File
Then click on Account
Underneath the Product Information Click on Office Updates
Select Update Now
A Microsoft Box will open and start running, it may prompt you to close some applications
When it is completed you will see this
After it is completed you should be able to login without an issue.
If a problem persists please reboot your computer and try again.
If that fails please open a ticket with our service desk.
