Windows 10: Need Registry setting... can't Turn OFF email sync for deactivated email account

I have an account added to Windows 10 Mail app... I can no longer access the account, the provider stopped providing email service. Win10 constantly reminds me the email needs to be updated, needs to be fixed, etc.
I want to keep the old emails, so I don't want to delete the account. Every time I try to change the sync settings (turn syncing off) for the account, I click the slider button to Off... but the change is not accepted. The next time I go to the sync settings, it is still ON.
I think there must be a registry setting for this... that I can edit. (I am comfortable with the Registry.)
Can anyone specify a key to edit for Win10 Mail account syncing?

Unauthorized Emails from my account?

It is more than likely that your email account was hacked, either by a virus sniffing your password, or just simply hacked.

Either way, change your password on your email account. Unfortunately the damage by already be done. They already have your contact list and your email address associated with that contact list. There is nothing stopping them from sending out emails using their own SMTP servers to everyone on your contact list and claiming the emails are from your email address. They don't actually have to have access to your yahoo account or even any yahoo server to send emails to people that come from your address.

 

email account hacked. please help

I have a yahoo email account that seems to be hacked. Following are hacking activities I have noticed.

1) Spam emails being sent from my account to my account and my recovery email account.
2) Recent emails in inbox are missing
3) New emails in deleted mails folder

I have reset passwords for both my email account and recovery email account and also re-installed my mac but still spam emails are being sent from my account to my account and my recovery email account.

My mac was not even turned on when those emails were being sent. No one else knows my password. I do access mail from my iphone and ipad too.

Its my primary email account please help.

Thanks

Don't think you can if they were deleted from your email account and are not in your trash folder. Try contacting Yahoo, explain what happened, and see what they can do or suggest you do.
