Windows 10: I keep receiving a pop-up asking me to sign in to Windows Security to download my calendar...

I have tried all my user names and passwords i.e. microsoft, admin, and yahoo but it has not fixed the issue. I also receive a message Microsoft OutlookAccess to the resource was denied. If you have signed into and saved your Microsoft account with a Web site, sign out of that Web site, and then try this operation again.

Windows Security sign in pop up

I just upgraded my Windows 10 with the latest update. Now I keep receiving a pop-up asking me to sign in to Windows Security. What is this? Thank you,

 

Windows Security sign in pop up

Since you are still getting this pop up window, the next suggestion we have is to reset the network. Kindly refer to the steps below:

• Click on Start.
• Go to Settings.
• Select Network & Internet.
• On the Status tab, click on Network reset.

Doing this will make Windows forget the connection credentials and other networking components. You may have to re-enter you WiFi credentials if you will attempt to connect to your home network.

Let us know the results.

 

Calendar app asking to sign in

Hi,



Thank you for writing to Microsoft Community Forums.



It is very unusual that the Calendar app is asking to add an account even though when the Mail app is already configured. I’ll help you with this issue.



However, please let us know:

• What is the version of Mail & Calendar app? To check, open
  Mail app, click on Settings (Gear icon) and click on
  About.
  
• Which build version of Windows 10 is installed on the computer? To check type:
  winver in the search bar on the Taskbar and hit
  Enter.
  

I would suggest you to refer the steps mentioned in the article
Fix problems with apps from Microsoft Store and see if that helps.



Note: Resetting the app will reinstall it and revert it to default settings. You will have to reconfigure the email accounts.



For additional information, see
Resolve sync issues in Mail and Calendar apps in Windows 10.



Let us know how it goes.
