Before you can use the Outlook Add-in for Office 365, you must be logged in to your Syncplicity account.
If you have the Syncplicity client or app on your desktop or device, you only need to log in once. If you are not logged in, you are prompted to log in when you open the Outlook Add-in.
In the Syncplicity pane, enter your username which is in the form of an email address. If not using a corporate account, uncheck the Login using a corporate account box then enter your password. If unsure, just click Login. You are prompted if you need to enter a password. Once you are logged in, you do not see another message or dialog box.
To log out, click Account Settings in the Syncplicity menu then click Logout.
