Office 365 Sign In To My Account
In Office 2013 apps, you can access Office 365 content in SharePoint Online by providing your Office 365 user ID and password. If you have multiple Office 365 user IDs from different organizations, you can access content from the SharePoint Online deployments of each organization.
However, Office 2013 only supports one Office 365 user sign-in from each tenant or organization per session.
Sign In To 365 Account
Office 2013 makes a best effort to prevent a second user from signing in when another user from the same organization is already signed in. However, there may be cases in which this scenario is not detected and the Office 2013 user interface may show that another user is successfully signed in. In this case, the second user cannot access his or her own content. All Office 365 content that he or she tries to open will be performed by using the first user's credentials.
Be aware that Office 2013 respects the permissions of all documents and SharePoint Online libraries. That is, if the first user doesn't have access to a document that the second user has access to, and the second user (who believes they are signed in) attempts to open that document, the document will not open because Office tries to open the document as the first user.
To fix this scenario, the signed-in user should sign out of Office 2013, and then restart his or her computer. Doing this makes sure that a clean state is present when the other user tries to sign in again.
If restarting the computer does not resolve the issue, then adjusting the registry is the recommended solution.
