I recently migrated my PC from one domain to another. This took some regedit changes...
Now one of the configured email accounts in the Windows 10 Mail and Calendar app is invalid. The email address is shown in quotes and the account has no functionality (does not receive, send or provide any options). The mail app does not show any warnings or errors except when I try to send a email. It does not provide any solution in any case.
I want to remove the email account, but I can't. What can I do?
Normally the email account could be removed via the account settings within the Mail app but the settings for this bugged email do not open. If I try to open the account setting the app doesn't do anything (for other email accounts it still works).
I did go into the app setting and did a full reset of the Windows 10 Mail app but that did not help.
I did deinstall the app from my PC and reinstalled it but the mail account is still there...
There were 3 accounts configured before. The other two were Exchange accounts and still worked after the migration. By the reset these were successfully removed but the bad account (imap configuration) stayed.
I'm out of ideas. Where are these configurations saved? Can I manually delete the mail configurations where ever they are stored? They seem to survive the deinstall.
Some screenshots for clarity:
