[German<\/a>]The mail and calendar app that's shipped with Windows 10 tends to fail. In my case, I was facing the situation, that no more mail accounts can be added, removed or viewed. Here is some information including a possible solution.<\/p>\n

The problem description<\/h2>\n

\"\"I was recently affected by this problem myself when I wanted to update a small beginner's book on Windows 10. In the section about setting up the mail app I was suddenly faced with the problem that it didn't work on Windows 10 20H2. For example, when I went to Settings – Manage Accounts – Add Account<\/em> from the app's sidebar, nothing worked when I selected the command. Here is a German screenshot of the popup window.<\/p>\n

\"Windows<\/p>\n

It was also not possible to select an existing account to view the configuration, nor to delete an account. A quick internet research showed me that this problem has been running through the mail app for years. This thread<\/a> in the Microsoft Answers Forum is from 2015 – we are writing in 2020 now. <\/p>\n

Cannot add accounts to mail and calendar on windows 10<\/p>\n

I've been trying to add an account to my windows 10 mail app but it doesn't work.  I try deleting it and reinstalling and still cannot add any accounts to mail or calendar app.  The add account button does not do anything or show any error messages.<\/p>\n<\/blockquote>\n

My machine is used for tests only, and has been updates to Windows 10 20H2 recently. There is no third party antivirus software and only Microsoft Office 2019 Pro Plus installed. <\/p>\n

First repair attempts unsuccessful<\/h2>\n

I then tried to repair the app by running wsreset.exe<\/em> (but only resets the store). Then I went to Settings -> Apps -> Apps & Features<\/em>, selected the app, and then clicked on the Advanced Options<\/em> command. There is a Reset<\/em> button to reset the app to the factory default settings. Alone it did not help. <\/p>\n

\"Windows<\/p>\n

The next attempt was to uninstall the app and then reinstall it via the Microsoft Store. The first time I started the app, the window for setting up a mail account appeared (picture above). But the Add account<\/em> option was dead, nothing happened when clicking it. So I was exactly as far as before.<\/p>\n

This repair method helped<\/h2>\n

In the US Microsoft Answers Forum you can find this thread<\/a> from 2015, I mentioned above. The poster wasn't able to manage (add, change, delete) accounts with the Windows 10 Mail App. There Alexei Stukov gives the crucial hint<\/a> that a capability OneCoreUAP.OneSync<\/em> is missing.  <\/p>\n

\n

Here the construction of Windows 10 strikes mercilessly. On this page<\/a> Microsoft writes that oneSync <\/em>is a feature on demand, that is installed on demand. It is an e-mail, contact and calendar synchronization component. If this component is missing, the mail app doesn't work. This is what it says: If you don't include this feature on-demand on your Windows image, UWP apps such as email, people and calendars will not synchronize properly.<\/em><\/p>\n<\/blockquote>\n

The missing feature can be added in an administrative command prompt \/ PowerShell console with the following command..<\/p>\n

DISM.exe \/Online \/Add-Capability \/CapabilityName:OneCoreUAP.OneSync~~~~0.0.1.0<\/p>\n

I ran the command in the PowerShell console (see the following screen shot). The installation took quite a while – but afterwards managing accounts of the mail app worked as expected<\/p>\n

\"Windows<\/p>\n

While researching for OneCoreUAP.OneSync, I came across this German article (deleted) by a fellow sufferered the same, who had also tried all kinds of repair attempts before. That's what I like on this 'Windows as a surprise' (Waas) – ok, I'm just kidding. I never used that buggy Windows apps at all – and Windows 10 is only valid as a test machine for me. <\/p>\n

\n

The above episode again showed me how fragile the whole construction of this 'Windows as a surprise' actually is. I have no idea which (feature-)update removed the on-demand capability OneSync<\/em>. But a normal user has hardly any chance to remedy this. <\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
