How To Delete An Outlook Profile from Registry?

Remove all traces of your personal email accounts by deleting hidden files and registry keys from your hard drive. While Microsoft Outlook stores your Outlook profile information in its Outlook data files — formatted as PST files — additional profile data exists in the Windows registry. Using Windows Registry Editor you can navigate to the registry keys for Outlook and delete your profiles from this location. The next time you open Outlook the application will attempt to reconfigure itself as if it were being run for the first time.

Step 1

Exit out of Outlook and any other Microsoft Office programs currently running on your computer.

Step 2

Press “Windows” to open the Windows Start screen, enter “regedit.exe” and then click “Regedit.exe” from the search results.

Step 3

Click “Yes” and then authenticate with an administrator account if prompted by User Account Control to open the Windows Registry Editor.

Step 4

Navigate to “HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Profiles” using the Registry Editor folder tree. Your Outlook profile folders are located here. Your default Outlook profile is labeled as “Outlook.”

Step 5

Right-click on your Outlook profile folder and then click “Delete.” For example, right-click on the profile folder named “Outlook.”

Step 6

Click “Yes” when prompted by the Confirm Key Delete dialog asking if you are sure you want to permanently delete the registry key and its subkeys.

Step 7

Exit the Windows Registry Editor and then restart your PC before running Outlook.
