How to Remove Cached Credentials from Credentials Manager
Using cached/saved credentials allows users to sign into their accounts without having to enter their credentials every time. However, outdated or incorrect cached credentials can cause sign in problems and lead to a potentially locked account. To remove cached credentials, follow the guide below.
To open Credential Manager, type credential manager in the search box on the taskbar and select Credential Manager Control panel.
Select Windows Credentials to access the credentials you want to manage.
Remove all Outlook or Connect entries.
How to Remove a Profile
When using the Outlook email desktop app, a pop-up message may appear asking for the user to select a profile. An Outlook profile consists of the accounts, data files, and settings that specify where your email messages are saved.
If you no longer need an Outlook profile, you can delete it and by doing so, this also deletes all email accounts stored in that profile. You can also create a new Outlook profile.
Open the Outlook app
Go to Control Panel > User Accounts > Mail
Press Windows + R > type Control Panel > OK
In Control Panel > User Accounts > Mail (32bit).
Click Show Profiles.
Select a profile (Outlook).
How to create an new Outlook Profile
Open the Control Panel and open the Mail settings.
Click the Show Profiles… button
Click the Add button
Type a profile name in the text box (it can be anything as long as it’s not the same as an existing profile name) and click OK
Type in your Email Account information and password and click Next (if the Email address field is already populated and the password field are missing, just click next)
Outlook will find your information based on Auto Discover settings. If everything is checked off, you can click Finish to complete the profile setup
Back on Mail settings window, change the setting for “When starting Microsoft Outlook, use this profile:” to “Always use this profile”, select your new profile name and click OK
You should now be able to start Outlook using the new profile.
