Temporary Service Disruption to Emailing of Invoices from Synergy

Microsoft released an update to the Issue ID EX921449 at 3:55 AM AEDT indicating they have addressed some issues that were delaying the script and have confirmed that 50 percent of all affected email messages have been released from quarantine.
They are continuing to monitor the script as it progresses towards completion.

As this update suggests, users with an email hosted by Microsoft Exchange Online should start to see their emails come through or re-appear over the course of the day.

Please refer to Microsoft's Service Health page (as a Microsoft 365 Admin) or through your IT Partner for further updates.

Thanks for your patience while we investigated this issue.

It has been identified that the issue impacting outgoing emails has been isolated to recipients who use Microsoft Exchange Online.
The emails being sent from Synergy, such as Invoices are being automatically quarantined by Microsoft Security.

We recommend those having the issue with receiving emails from Synergy, reach out to their IT team and request they look into MSFT Alert ID "EX921449".
- Open office 365 admin centre
- Navigate to Health
- Find the Exchange online alert

Our technical team are continuing to investigate this to help resolve the impact this is having on Synergy emails, and we will continue to provide updates as they become available from Microsoft.

Between approximately 6am - 1pm AEDT today, there were delays experienced with the sending of invoices. Invoices are appearing in Synergy as sent, but invoice emails have not been received by customers.

We are currently investigating the issue. If the invoice is urgent, we recommend downloading the PDF from Synergy and attaching it to an email manually. Please note, that customers may receive the invoice again once the backlog is cleared.

We apologise for any inconvenience and will keep you updated as we work to resolve the issue.
