1. Open up control panel
The fastest way is to normally press the ‘Window’ key (for search) they type in ‘control panel’
2. Click on ‘Mail’ options
3. Click on ‘Email accounts’
4. Click on the account you’d like to delete then click the ‘remove’ option
5. Close ‘mail options’, ‘control panel’ and ‘Outlook’ then re-start ‘Outlook’
Before removing a mail account, check where its messages are stored and make a verified backup of any local-only mail. Removing an Outlook profile/account is not the same as closing the provider’s mailbox. These Control Panel steps describe classic Outlook for Windows, not every Outlook version.
