I had a Microsoft update last night. This morning the internet connection is working. Outlook does not connect with the server this morning, although it was fine last night.

    This is likely the result of the current service side issue affecting a large number of customers.

    Unfortunately this is still the ongoing recovery.

    You can monitor the latest updates via https://status.cloud.microsoft/

    Here is the latest available information:

    User impact: Users may be unable to access or perform several actions in Microsoft 365 services.

    Current status: Our recovery efforts to restore service health throughout the affected environment is progressing. In parallel, we're continuing to pursue multiple workstreams to pinpoint the source of the issue and ensure the recovery of the affected environment. This issue impacts Outlook.com, OneDrive, OneNote, Microsoft To Do, Teams, and Microsoft 365 for the web although you may also see issues in other Microsoft 365 services.

    Try these checks in order:

    1. In Outlook, make sure it is not set to work offline.
      • Go to Send/Receive and confirm Work Offline is not enabled.
    2. Install the latest updates.
      • A recent update can leave Outlook or Windows in a bad state until all updates are fully applied.
      • Run Windows Update and install any remaining updates, then restart Windows.
    3. Run Microsoft’s Outlook connectivity tool.
      • Use Support and Recovery Assistant for Microsoft 365 to diagnose common Outlook connection problems.
    4. If the account is IMAP or POP and the error mentions the server connection being interrupted:
      • Re-create the App Password with the mail provider, then update it in Outlook:
        • File > select the affected account under Account Information
        • Account Settings > Server Settings
        • Paste the new app password in Password
        • Select Next > Done
    5. If the account is IMAP or POP on Windows 10 and this started after updates:
      • Warning: this step edits the registry.
      • Open Regedit and go to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
      • If TLS 1.3 exists under Protocols, first Export the key as a backup.
      • Delete the TLS 1.3 key and its subkeys.
      • Restart Outlook. If sync still does not start, restart Windows.
    6. If Outlook shows a proxy or certificate error:
      • Start Outlook in safe mode: Start > Run > outlook.exe /safe
      • If Outlook works in safe mode, disable third-party COM add-ins:
        • File > Options > Add-Ins
        • In Manage, select COM Add-ins > Go
        • Clear the third-party add-ins
        • Restart Outlook
    7. If multiple people in the household or organization using Microsoft 365 are affected, an admin should check Exchange Online service health.
