Fix On-Prem to Microsoft 365 Sync

Job ID: 40476235

Budget: $30 – $250 USD

I began seeing sync errors less than 24 hours ago and need fast, decisive help getting our on-prem domain controller back in step with Microsoft 365. The failures touch the core services we rely on—Active Directory, Exchange Online and SharePoint Online—so user creation, address book updates and permissions are now out of alignment.

What I need from you
• Pinpoint the root cause behind the current sync failures.
• Restore a clean, successful sync cycle and verify that all three services reflect on-prem changes properly.
• Provide a short hand-off note outlining the steps you took and any preventive measures I should keep in place.

I can supply remote access to the server and the Microsoft 365 admin portal as soon as we agree on the engagement. If additional logs or traces are required, just let me know the exact commands or tools to run and I will collect them for you.

The job is complete once a full sync runs without errors and the latest on-prem AD changes are visible in Exchange Online and SharePoint Online.
