After signing out of Office 365, when attempting to "switch accounts" within Office 365 I am unable to sign back in via any of the Office 2013 application using my account. I am, however, able to successfully sign in through the website. The problem occurs on numerous machines, on and off-site, within and without our Active Directory network. I have completely uninstalled and re-installed Office 2013 without resolve.

Hi,

I wrote a blogpost on how to get the sync process up and running again. This might also be applicable to your question. Try taking the steps as described in the post:

Thanks for the reply and i did try your steps but no joy :(

Hi,

Sorry to here that it did not work. Have you tried removing the services from for example Microsoft Word? If you go to file - account you can add and remove services. Remove the service first close word and then add the service again.
