After you install an update, you might have problems with Microsoft Outlook. For example, Outlook might keep asking you for your password even if you’ve checked the box to remember it. But you can fix this quickly by making a small change in the Registry.
Outlook not saving passwords
There are several possible reasons for this issue, but a simple Registry tweak can fix it all. So, if Outlook is continually prompting you for a password, do the following:
- Open Registry Editor.
- Navigate to the following key – HKCU
- Expand the key options and go to the Auto Discover folder
- Create a new DWORD and name it ExcludeExplicitO365Endpoint.
- Set the value of the above key to 1.
- Save the changes and exit.
- Restart Outlook.
The Registry Editor can cause serious problems if used incorrectly. You may need to reinstall Windows to fix them. So, first create a system restore point.
Open the registry editor by pressing Win + R in combination, then typing Regedit in the empty field, and pressing OK.
Navigate to the following key:
Double-click the Outlook folder to select the Auto Discover folder.
Switch to the right-pane and create a new DWORD value. Name it as ExcludeExplicitO365Endpoint.
Now, double-click on the ExcludeExplicitO365Endpoint entry, and in the Edit String box that appears, change the value from 0 to 1.
Close the Registry Editor.
Restart your Outlook app and check if the user password is saved.
You should no longer see the Outlook password prompt.
Some folks report that Windows 10 updates might interfere with the cached passwords of email and other websites and even delete them. Nevertheless, this trick will help you resolve the issue, successfully.
