Device & OS: not provided
Scenario: Importing pasted data into a project schedule and expecting those updates to reflect accurately in Microsoft Roadmap.

Solution 1Recommended

Submit a Support Request via Microsoft 365 Admin Center

Since this issue involves backend synchronization logs and server-side configurations, it requires direct intervention from Microsoft Support specialists.

Unexpected date changes during data imports and failures in Roadmap synchronization often stem from backend scheduling engine conflicts or broken Power Automate flows. These cannot be resolved through standard user settings.

Microsoft Support specialists have the necessary access to review background logs, analyze project configurations, and identify the root cause of the syncing failures.

Access the Admin Center

Navigate to the Microsoft 365 admin center at admin.microsoft.com and log in with your administrator credentials.

Navigate to Help & Support

Locate the left-hand navigation menu, click on 'Support', and then select 'Help & support'.

Create a New Request

Enter a description of the Project Online date changing and Roadmap syncing issue, then submit a formal service request for the support team to review your backend logs.

Coordinate with Your IT Team

If you do not have administrative privileges, provide the documented errors to your organization's IT administrator and request that they open the support ticket on your behalf.

Administrator Privileges Required: Only users with Microsoft 365 administrator rights can access the support portal to create a ticket. End-users must route this request through their internal IT department.

Frequently Asked Questions

Why do task dates change automatically when pasting data into Project Online?

Task dates can shift automatically due to the background scheduling engine, assigned working time calendars, resource constraints, or task dependencies. If the behavior contradicts your set rules, backend logs must be reviewed by support to find the configuration error.

How does Microsoft Roadmap sync project updates?

Microsoft Roadmap relies on backend Power Automate flows to pull data from Project Online. If a flow fails or loses its connection authentication, the Roadmap will fail to reflect recent project changes.

Can standard users submit a support ticket for Project Online issues?

No, standard users cannot directly create a support request in the Microsoft 365 admin center. You must contact your organization's Microsoft 365 administrator or IT department to submit the ticket for you.
