    Hello, thank you for reaching out to Microsoft Q&A.

    1. May I please know the exact error message you receive when you sign in with your Microsoft account?

    *Is the affected email address for a personal Microsoft account (e.g., ending in @outlook.com, @hotmail.com, @gmail.com that you created for services like Skype or Xbox) or a work/school account provided by an organization (e.g., ******@company.com)?

    1. Could you please let me know which services (such as OneDrive, Outlook, OneNote, etc.) you are experiencing sync issues with? Are you seeing any specific error messages?

    Please also provide more detailed information about the problem you’re encountering. This will help us better understand the situation and guide you in the right direction.

    For sync issues and sign-in problems, start with these checks and fixes:

    1. Check for two-factor authentication (2FA)
    • If the account uses two-factor authentication, the Windows 10 Mail and Calendar apps do not support it directly.
    • In that case, create an app password with the email provider and use that app password instead of the normal password in the Mail app.
    • Instructions for creating an app password are provided by the email provider.
    1. Check for error 0x80072726 (or similar sync errors)
    • Error 0x80072726 can be caused by third-party firewall or antivirus software blocking the connection.
    • Temporarily turn off the third-party firewall/antivirus to test whether sync starts working.
      • If sync works with the security software disabled, visit the security software vendor’s site or contact their support to configure it so email can sync without turning protection off permanently.
    • While antivirus is disabled, do not open attachments or click links in messages from unknown senders.
    1. If using Outlook.com / Microsoft account (Live/Hotmail/MSN)
    • For general Outlook.com sign-in or sync issues (including Microsoft “live mail” accounts), use the Outlook.com help and troubleshooting resources:
      • “Fix Outlook.com email sync issues, including sign-in problems” for issues sending/receiving or signing in.
      • “Fixes or workarounds for recent issues on Outlook.com” for known current problems.
      • “Unblock my Outlook.com account” if the account has been temporarily blocked.
    1. If using Outlook mobile (iOS/Android) and having setup/sync issues
    • If Outlook is already set up but not syncing correctly, open the app and use the in-app “Contact Support” option to chat with support.
    • If the problem is during setup, follow the “Troubleshoot email setup on mobile” guidance.
    • If calendar/contacts are not syncing on first-time setup, use the “Sync calendar with my phone or tablet” guidance.

    If more detail is available on the exact error codes or which app (Windows 10 Mail, Outlook desktop, Outlook.com in browser, or Outlook mobile) is affected, the troubleshooting can be narrowed further.
