Incident impacting Hosted Microsoft Exchange 2016

We continue to examine all aspects of this issue both internally, and in conjunction with Microsoft to fully address the underlying cause of the Exchange latency that was experienced by some customers last week. Integrated within that process, we’re still working on the root cause analysis. However, network performance and mail flow remain at optimum levels and we continue to see no customer impacts associated with this issue. Throughout the extended troubleshooting process, we discovered other opportunities for efficiency and we are working to fully incorporate those, as well.

We’re marking the issue as resolved from a customer impact standpoint, but we continue to closely monitor and adjust the Exchange service for performance and efficiency. A root cause analysis will be available once the validation process has been completed.

We continue to monitor the hosted Microsoft Exchange service for any connectivity issues, but performance is still fully tracking as optimal. So far, the only issues we have discovered have been with a few customers who haven’t restarted their mail client since last week and were still receiving authentication requests. Once the mail client was restarted, all authentication and password prompt cleared. No other negative impacts or latency issues have been identified.

Our engineering team is still working through the validation process and we’ll post more on the final details and the root cause of this issue when that process has been completed.

Over the weekend, our Engineering team made significant progress toward resolving the hosted Microsoft Exchange service latency that was being experienced. Mail flow and CPU performance remains optimal and we are closely monitoring to ensure that connectivity issues with our Exchange service have been fully resolved. We’ll post more on the final details and the root cause of this issue once the complete validation has been accomplished.

Mail flow and message queues remain normal, but random Outlook Web access and Microsoft Outlook timeouts are still occurring, along with intermittent connectivity drops resulting in authentication and password prompts for some hosted Microsoft Exchange customers. We continue to closely monitor and adjust our Exchange platform in order to counteract any experienced latency. Systems Engineering is diligently working with Microsoft to determine the underlying cause for this Exchange issue and will continue to do so throughout the weekend until the issue is identified and fully addressed.

Of course, any change or advancement in status will be posted and shared throughout the weekend – but we won’t post unnecessary updates as long as the status remains the same.
