To remove an old corporate (work) account from classic Outlook for Windows, use the Account Settings dialog in classic Outlook. Removing the account only disconnects it from Outlook; it does not deactivate or delete the mailbox at the company.
Follow these steps in classic Outlook for Windows:
- Open classic Outlook.
- Select File (top-left corner).
- Select Account Settings > Account Settings.
- On the Email tab, select the old corporate account.
- Select Remove.
- When prompted that offline cached content will be deleted, select Yes to confirm.
If this is the last or only email account in Outlook, Outlook will warn that a new data file/location is required before removal. In that case:
- First create a new Outlook Data File as a place to store data: see Create an Outlook Data File in the linked article.
- After the new data file is created and set as the default data location, repeat the steps above to remove the old corporate account.
This will remove the ex-corporate account from classic Outlook so it no longer appears or sends/receives mail there.
