If you are using Microsoft Office 2010: (from Microsoft: https://community.office365.com/en-us/f/172/t/268139)
- Clear the user credential from Credential Manager:
- Click Start, click Control Panel, and then click Credential Manager. Note If View by is set to Category, click User Accounts first, and then click Credential Manager.
- Locate the set of credentials that has Outlook in the name.
- Click the name to expand the set of credentials, and then click Remove from Vault.
- Repeat step 3 for any additional sets of credentials that have the word Outlook in the name.
- If the Office 2013 is not downloaded from the O365 portal, try uninstalling it and
re-installing from the portal if possible. If using Office 2013, and Outlook keeps
asking for your username and password try creating another profile for Outlook. You
can call it anything you want to and tell Outlook to use the new on as default.
A profile consists of accounts, data files, and settings that specify where your email messages are saved.
- Exit Outlook.
- In Control Panel, click or double-click Mail.
Where is Mail in Control Panel? Mail appears in different Control Panel locations depending on the version of the Microsoft Windows operating system, Control Panel view selected, and whether a 32- or 64-bit operating system or version of Microsoft Outlook is installed. The easiest way to locate Mail is to open Control Panel in Windows, and then in the Search box at the top of window, type Mail. In Control Panel for Windows XP, type Mail in the Address box. Note The Mail icon appears after Outlook starts for the first time. The title bar of the Mail Setup dialog box contains the name of the current profile. To select a different existing profile, click Show Profiles, select the profile name, and then click Properties.
- Click Show Profiles.
- Click Add.
- Type a name for the profile, and then click OK.
