When you attempt to install or update an app via the Microsoft Store app, you may receive the error 0x80070426. The following is the full error message verbatim:
Something went wrong Please try again later. 0x80070426
Windows Store

In some cases, you may see a gray (sign-in) dialog with nothing visible.

Office 365 apps
In the Office 365 apps, you may see a warning symbol at the top, which when clicked, shows the following error:
Account Error Sorry, we can't get to your acount right now. To fix this, please sign in again.

If you click on the Fix me button and try to sign-in to your MSA, the error 0x80070426 pops up.

Mail app
The mail app may not connect to your Microsoft Hotmail or Live mail account. It would show the same error 0x80070426.

Switching to MSA
Also, you won’t be able to switch to a Microsoft account (MSA) from a local account. Doing so causes the error "Oops, something went wrong"
