The popular Microsoft Outlook program allows multiple accounts to be set up on a single computer. By default, one selected account automatically signs in each time the program opens. This can be frustrating if you have multiple accounts on your computer, but cannot figure out how to use them. In order to switch accounts on Outlook, a change must be made to the profile settings. Once changed, Outlook will give you a choice of accounts to sign in to, each time it loads.
Close Outlook if it's currently open.
Open the "Control Panel" from the Start menu.
Click on "User Accounts" and then select "Mail" to access the Outlook settings. A "Mail Setup" window will pop up.
Click "Show Profiles" on the Mail Setup window.
Select "Prompt for a profile to be used" and click "OK." This will instruct Outlook to ask which profile you want to use each time it's opened.
Open the Outlook program and choose the account you wish to use. When you want to switch to a different account, close and then reopen Outlook.
If you use Outlook 2010, multiple accounts automatically stay open. Each account can be accessed from the left side of the Outlook window.
