A profile consists of 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. Deleting a profile deletes all email accounts stored in that profile. Any Outlook Data Files (.pst) associated with that profile remain on your computer, but to access that data, you need to open the file from within another profile.
- In classic Outlook, select File > Account Settings > Manage Profiles.
- Select Show Profiles.
- Select a profile, and then select Remove.
Note
Outlook might warn you that deleting your profile removes offline data. You don't lose any information stored in your Outlook Data Files (.pst) or any information stored in your online accounts, such as Outlook.com, Exchange, or Microsoft 365 accounts.
If you can't start classic Outlook, you can access the Show Profiles window by typing outlook.exe /manageprofiles in the Windows search box and pressing Enter.
