At times, Outlook can prompt a user to re-enter their email password for an account established within. This can occur as a result of a change in the password, expired session data, and more. Below are the steps one would take to correct this issue:
A user of Outlook can experience the issue of being prompted to re-enter their email account password with the dialog box below. The user would want to enter the correct password in the Password: field for the specified account then check the box for Save this password in your password list.
If the steps outlined above does not resolve your issue and the password box continues to appear, follow the steps outlined below:
Open Control Panel by going to Start/Control Panel
In Control Panel, Select the Mail icon if you are in small or large icon views. If you are in Category view, you will access the Mail icon under User Accounts and Family Safety
After selecting the Mail Icon, The Mail Setup dialog box will appear. Select Email Accounts within the dialog box.
After selecting Email Accounts, the Account Settings wizard will appear. You will select the account then select Change or you may double-click on the account.
After selecting the account you wish to update the password for, the Change Account wizard appears. You will want to re-enter the password here then select Next. A Congratulations pane will appear, be sure to select the Finish option to preserve the changes.
Once you have completed the above steps, close out the remaining boxes and re-open Outlook.
