Windows 10: Windows Mail Cannot Remove Account, logs AccountsControlHost.exe error 0x40000015

I broke something.

I tried to add an old email account to Windows Mail.


Windows Mail automatically detected my IMAP and SMTP servers, but it listed them strangely.
IMAP was - secure.emailsrvr.com:993:1
SMTP was - secure.emailsrvr.com:465:1

The account wouldn't sync. I thought it was strange that there was the extra :1 on the end, so I deleted it.

That's when things got weird...


Mail froze and wouldn't back out of the account settings window.

I tried the following:
I reset the mail app from system settings > unwanted account is still there.

I uninstalled the app with powershell then reinstalled > unwanted account is still there.

I restored my computer to an earlier date > unwanted account is still there.


I want to avoid resetting my PC.

This ONLY affects MY profile, none of the other profiles are affected.


This is the account I want to remove:




These are the errors that pile up when I try to open "Account Settings" for that account:




I can't understand why this issue persists after uninstalling and reinstalling Mail and Calendar.


I can provide error log files upon request.

Vista Windows Mail error in account setup

I’ve been using Windows Mail (Vista 32 bit) for almost a year with no problems. Recently my email account in windows mail was deleted, and I did not do it ! I have tried many, many, many time s to add my account back in and it will not add it. After I click finish on the last screen I receive the following error msg: “An error occurred while reading the new account information. No changes have been made.” …my account is not added. I also verified that I’m typing my password in in lower case as it should be. I have even phoned Comcast to verify my entries on each screen and they are correct (incoming/outgoing servers, etc). I also installed Windows Live Mail and I had the exact same error msg. In Windows Live Mail I can set up the account manually and in the outgong server, Comcast uses port 587 so, I can specify that port and it still does not help. I don’t think there is a problem in the software, I think it’s somewhere else in my OS, system, or ports or something… I have no clue. Also, I've started worrying if I have a trojan or malware that Avast and SpySweeper cannot detect. I did a boot-time sweep with Avast and it did not find anythng. Prior to that I did a scan (in the OS) and Avast found a malwre in an MP3 file downloaded from Limewire. It quarantined it and I deleted it. I did a system restore (using Vista's restore points) back about 5 days and still had the same problem. Did a restore back further and still the same problem. So, I still don't think the problem is in the software... gotta be some where else.

Can anyone help ? please ?

0x8000FFFF Mail App error setting up hotmail account

I got the solution!!!!!

You have to go to your account in windows settings, and change your microsoft account ex "*** Email address is removed for privacy ***" to local ex "hallo", and then you have to log out, and log in with your local account ex "hallo".

Now you can delete your mail account in mail and calendar. When you are done.

Then go back again to your account in windows settings, and change your local account ex "hallo" to your microsoft account ex "*** Email address is removed for privacy ***", and then you have to log out, and log in with your microsoft account ex "*** Email address is removed for privacy ***"

Now mail account and calendar account works again, it is magic!!!!
