With the increased penetration of mobile devices like mobile phones and tablets an array of email clients have materialized but Microsoft’s build in mail client ‘Outlook‘ is the world’s most-popular by far. But some Windows 10 users have reported that it shows the wrong email account in the account settings. If you too are facing this problem, then there’s a workaround for this problem. Please note that using Registry Editor incorrectly can cause serious problems, so we recommend that make a backup of the Windows Registry before you modify any settings.
Before you proceed, Switch to and sign in with a local account and thenagain revert back to your Microsoft account and see if it helps. You will be able to do this via Settings > Accounts.
Wrong Email alias, address or ID showing in Outlook
This tweaking doesn’t require an in-depth knowledge. Following these few simple steps very carefully, and you are done!
Press Win+R in combination to access the ‘Run’ dialog box. In the registry editor that opens navigate to the following path in the left pane:
Click on Partners to expand it. Probably the first folder you see, which contains a string of characters for name, is the one you need to modify.
Upon clicking on this folder a string called “Email” should be visible to you in the right-pane.
It shows you your wrong main alias. Right click on this string and select. “Modify.”
DO NOT modify the string below called “EmailAddress“. This string lists all your aliases you have attached to your account, you want to keep this the same.
Now, enter the correct email address which is the same as the one you used to log in to your Windows 10 Device. Click “OK”.
Close the registry editor and restart your computer.
Upon restarting, simply open the Outlook mail client and you should find the correct Email address displayed for your main Microsoft account.
