Solution 1Recommended

Monitor Microsoft 365 Message Center for Rollout Updates

Verify if the missing features are part of an ongoing staged deployment or a paused rollout by checking Microsoft's official status.

Microsoft frequently uses staged deployments for new Microsoft 365 features. It is common for features like the Banner web part to appear and then temporarily disappear if the rollout is paused or adjusted due to detected issues. Monitoring the Message Center is the best way to track availability for your specific tenant.

Access the Admin Center

Navigate to the Message Center

On the left-hand navigation pane, expand the 'Health' menu and click on 'Message center'.

Search for the Feature Rollout

Use the search bar to look for specific rollout notification codes, such as MC791596, which relates to SharePoint header and banner updates.

Check the Deployment Status

Review the timeline provided by Microsoft. If the feature was retracted, you must wait for the rollout to resume and reach general availability in your tenant.

Staged Deployments: Feature availability can fluctuate wildly during late July or specific rollout windows. Support tickets are generally not required unless the feature is marked as 100% deployed but remains missing.

Solution 2

Temporarily Restore Existing Page Headers

Revert to standard SharePoint header layouts to maintain your site's appearance while waiting for the new banner options to fully deploy.

Frequently Asked Questions

Why do new Microsoft 365 features appear and then disappear?

Microsoft utilizes staged rollouts to deploy updates gradually. If performance issues or bugs are detected during the early stages of a rollout, Microsoft may temporarily retract the feature to fix the underlying problem before resuming the deployment.

Where can I find the exact rollout schedule for SharePoint updates?

You can track the deployment schedule by logging into the Microsoft 365 Admin Center, navigating to Health, and selecting Message center. Search for the specific feature announcement or its associated MC code (like MC791596).

Can I force the new SharePoint Banner web part to appear on my site?

No, feature availability is controlled entirely at the tenant level by Microsoft's deployment servers. Site administrators and owners must wait until the rollout naturally reaches 100% general availability for their specific tenant.
