We will mark this incident as resolved, all our services have returned to function as normal.

Emails are now delivering and being received as expected. This includes @rosterr.work, @teamrosterr.com, @rosterr.group and @rosterr.email. Support can be contacted on support@rosterr.work or via out live chat as normal.

We're seeing continued recovery progress across affected regions, with broader improvements now observed in North America and sustained improvements across much of Europe. We're also seeing encouraging recovery signals in Asia Pacific, although some users may continue to experience intermittent access issues or delayed email delivery as mitigation progresses across the remaining affected infrastructure. Our focus remains on stabilizing recovered infrastructure, completing mitigation in the remaining impacted areas, and reducing delayed email queues and backlogs. We're closely monitoring service consistency and validating recovery across different connection methods as we work toward full mitigation. At this time, we have no evidence of malicious activity associated with this incident. We will continue to treat this with urgency until full mitigation, and we will share a full Post-Incident Report with root cause and defense-in-depth actions after mitigation is complete.

Microsoft has published a further update.

We’re seeing encouraging recovery progress in Europe, with service availability and email delivery performance improving across a growing portion of affected Microsoft 365 infrastructure. Japan remains comparatively more stable, while North America is also improving; however, some users may still experience intermittent issues as recovery actions continue. We're focused on addressing the remaining areas of disruption and improving service consistency across affected regions. Reducing email queues and backlogs remains a priority, and the extended 48-hour email timeout window remains in place to help protect delayed messages as delivery catches up. At this time, we have no evidence of malicious activity associated with this incident. We will continue to treat this with urgency until full mitigation, and we will share a full Post-Incident Report with root cause and defense-in-depth actions after mitigation is complete.

I have pushed a patch allowing the @rosterr.work support inbox to work again by moving it to another mail server, all @teamrosterr.com, @rosterr.group and @rosterr.email email address are still unavailable. Thank you for your patience.

We are aware of delays wth our email server. We rely on Microsoft 365 servers.
Despite Microsoft's latest update, we are still unable to get to our emails.
