Mail app - don't want it but keeps nagging account wrong

Hi fols

I don't want or use the built in Windows mail app but on logon to windows it opens with a always get a prompt -- Your Ms account needs fixing.

I use local accounts so how can I get rid of this annoying popup after a Windows boot. I've also deleted One drive as well - I don't bother with cloud servers etc. I have Thunderbird and Office 2016 for email -but I can't see any way on deleting the mail app.

On the latest W10 Pro X-64 after the latest set of updates.

Cheers

The Windows Communications Apps let you interact with people through email, calendars, and social networks.
(Windows Communications Apps privacy statement)

In powershell (admin):

Get-AppxPackage *microsoft.windowscommunicationsapps* | Remove-AppxPackage

should remove mail and a bunch of other like calendar etc... (see the link)

Just remove your Account(s) from the Windows 10 Mail App.
The Mail App potentially has many links to other Apps, People and Calendars are two of them.
All you have to do is go through is the Windows & App Settings.

Same with OneDrive you can just side line that the same way.
