Windows 10: Mail app account already exists

I recently reset the Mail app on Windows 10 but now can't sign in and get an error message saying the account already exists. I have tried the answer at https://answers.microsoft.com/en-us/windows/forum/apps_windows_10-outlook_mail-winpc/mail-account-already-exists/e0904cc7-248f-4469-8ec8-78842fcf61e5 but it just throws me to the Microsoft account website when I click to manage account and can't get any further. Using Windows 10 version 1803. How do I sign back into the Mail app?

Get 'Account already exists' in Win10 Mail app


I was having problems with one of my accounts in Mail, so did what I have done before - deleted and re-installed. Except that Mail says that account already exists and will not allow me to install it.I have looked through all the postings in MS forums related to this topic and found some good comments and suggestions. I tried the Powershell scripts to uninstall Mail, which worked (after a very long time), then re-installed Mail. It immediately recognised my Gmail account, which surprised me, as I expected to have to re-enter each of my accounts. When I added my other account, it came back with the very same message "Account already exists".
Suggestions?

 

Mail app will not open on 10041.


Hello Adam,

This is the suggested solution below if you haven't already tried it. *Smile

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)
