    Hi @Phasha, Mosimanegape Peter M ,

    According to Microsoft's notification, users may be unable to connect to or access multiple Microsoft 365 services, including Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot, and Microsoft Defender XDR.

    Microsoft has identified that the affected infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors. Microsoft is currently restarting and repairing impacted portions of the infrastructure to restore capacity. Additionally, they are investigating an unexpected increase in a specific type of service traffic and evaluating options to redirect traffic to alternative infrastructure to expedite recovery.

    Microsoft is currently working to improve server stability by adjusting traffic protocols, redistributing traffic, and applying strategic traffic-blocking measures. Although partial recovery has been observed in some regions, these mitigation efforts have not yet resulted in sustained recovery. Microsoft is continuing to investigate additional measures to improve overall infrastructure stability.

    The incident is currently classified as Service Degradation, and Microsoft is actively working to mitigate the issue.

    If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center to view the details of this issue.

    If you're not an admin and don't know who the admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support    

    Ask your admin to follow these steps:

    • Sign in to the Microsoft 365 Admin Center.
    • Go to Health > Service Health.
    • Search for Issue ID: MO1550821 or EX1550543.
    • Select the issue and expand the details to review the latest updates, affected services, impact, and remediation information.

    I'll continue to monitor this case and let you know if there is any update.

    Kind regards.

    The current, tenant-specific update for EX1550543 must be checked in Microsoft 365 Admin Center under Health → Service health, because the available public reports do not provide a live, timestamped recovery status for affected African tenants.

    Check the incident status

    1. Sign in to the Microsoft 365 admin center with an administrator account.
    2. Go to Health → Service health.
    3. Under Active issues Microsoft is working on, select EX1550543.
    4. Review:
      • Status
      • Last updated
      • User impact
      • Affected services
      • All updates
      • Any mitigation or workaround specified by Microsoft

    Service Support administrators and Helpdesk administrators can also view Service health; Global Administrator access is not required. The incident entry shown for your organization is more authoritative and may be newer than public status summaries.^1^

    Public reporting previously indicated that EX1550543 could affect Microsoft 365 connectivity outside its initially reported region, but it did not provide a separate, confirmed recovery status for Africa.^2^

    What to do while EX1550543 is confirmed for your tenant

    If the dashboard associates your tenant with EX1550543:

    • No Outlook profile recreation, Office repair, reinstallation, or device reset is required unless the incident update specifically directs it.
    • Continue monitoring All updates for Microsoft’s mitigation progress.
    • Mailbox access should recover as Microsoft completes the service-side remediation; Exchange Online incidents already being handled by Microsoft generally do not require a separate support request.^3^
    • To receive updates, open the incident and select Manage notifications for this issue. Alternatively, use Service health → Customize → Email to subscribe to Exchange Online incident notifications.^1^

    If EX1550543 is no longer active

    Check the Issue history tab, which displays incidents resolved within the previous 7 or 30 days.^1^

    If EX1550543 is absent from both Active issues and Issue history, but users in Africa still have Outlook or Exchange Online failures:

    1. In Service health, select Report an issue and submit the symptoms and affected-user scope.
    2. Open a Microsoft 365 support request from the admin center.
    3. Include:
      • Affected users and locations
      • Outlook desktop versus Outlook on the web results
      • Exact error messages
      • Failure start time in UTC
      • Whether sending, receiving, authentication, or all mailbox access is affected

    If the admin center itself is unavailable, use Microsoft’s public Service Health Status page.^4^
