Question details

Users are unable to reliably access shared Sway newsletters due to slow loading times, intermittent connections, or complete page failures.

Product: Microsoft Sway
Device & OS: not provided
Scenario: Parents, carers, or team members attempting to view a shared Microsoft Sway newsletter link for organizational or school updates.
Observed behavior: The Sway newsletter takes an unusually long time to load, loads only partially, or fails to open entirely, often indicating a service or tenant-specific issue.

Before you start

Ensure your device has a stable internet connection and try opening the Sway link in a private or incognito browsing window to rule out basic cache issues before proceeding with advanced troubleshooting.

Solution 1Recommended

Check the Microsoft 365 Service Health Dashboard

Verify if the access issue is caused by a widespread Microsoft server outage, such as the previously resolved incident SW807143.

Microsoft Sway occasionally experiences infrastructure issues that cause slow or intermittent loading globally. If a service incident is active, you must wait for Microsoft engineers to deploy a fix.

Access the Admin Center

Navigate to Service Health

On the left-hand navigation menu, click on 'Health' and select 'Service health'.

Review Active Incidents

Look under the active issues tab to see if there is an ongoing advisory for Microsoft Sway. If an incident like SW807143 is listed, Microsoft is already working on a resolution.

Check the Microsoft 365 Service Health Dashboard

Administrator Access Required: Only users with administrative privileges can view the detailed Service Health Dashboard. Standard users should contact their IT department.

Solution 2

Generate HAR Logs and Submit a Support Request

Collect network diagnostic logs and escalate the issue to Microsoft Support if no global incidents are reported on the dashboard.
