Windows Server Essentials E-Mail Service Failing

After recently completing a migration from SBS 2003 to Server Essentials 2012 R2, moments after decomissioning the old domain controller, the essentials e-mail service which is responsible for handling the cloud sync to azure and office 365 will not start.

Microsoft are stumped by this too so I wondered if there was anyone else out there that had similar issues with 2012 essentials r2 since installing windows updates.?

I lost access to this account so apologies for the late response.

This issue was resolved by the Microsoft dev team. It was caused by the same microsoft online account being added to 2 AD users via the dashboard. This was caused by the fact the dashboard did not refresh with the up to date information once the first account had been added.

To resolve this, one of the duplicate AD accounts had to be deleted and recreated from scratch, The service then started up again.

Can you be more specific? The o365 integration wizard will not run while the SBS 2003 server is still ON the network, and yet your question implies that it had been run and was working. This is contrary to how the system behaves. Please be specific about the environment, what has been done, and what errors you are getting.

Just to be VERY clear, essentials does not have an email service. It has an integration service that makes it easier to create o365 accounts easier (seamless actually) when creating users through the essentials dashboard. No email service runs locally and no syncing of data occurs.

Apologies for the lack of specifics.

The FSMO roles have been transferred, exchange decommissioned (by deleting the server object out of ADSI) and the old server removed from the network.

We then began with the Office 365 integration wizard and began assigning pre-existing Microsoft Online accounts to our users so passwords would sync to the cloud. It worked for about an hour and then all of a sudden, the microsoft online status for all accounts was "unknown", the details from the office 365 tab became "unknown" also.

The only changes that occurred during this period was adding the DHCP role and decommissioning all the old small business server group policies and... windows update which included the latest rollup.

The only link to this "unknown" status is the fact that this e-mail integration service has stopped.

I'm struggling to understand what is stopping this from running. The actual event log is confusing.

Make sure your clock and time zone are both still correct. Open the services control panel and verify all automatic services are in a running state.
Cliff GaliherCommented:
And again, for clarification, you say this is 2012 R2?? You also say updates included a rollup. Essentials 2012 R2 does not *have* any rollups, so as before, some inconsistency exists in your description.

Microsoft support resolved the issue after a lengthy debugging process.
I am having the exact same issue.  The dashboard shows "unknown" for all Microsoft Online Accounts, and no information in the Office 365 integration tab.   Windows Server Essentials Email Service is stopped.   If I manually restart the service, all is good.   Checked AD and no issues with duplicate accounts being assigned (as tegenius noted).   Any help on this?
tegeniusAuthor Commented:
It was caused by 2 accounts having the same e-mail address in the local directory. One had successfully synced to the cloud but the other hadn't and was causing the whole synchronisation to fail. Best using powershell to export your AD to csv and checking all your accounts over.

As for your exact issues, not sure :( Microsoft support may be able to help, even the Azure AD team on 365 :)
