TLU e-mail and various other Office 365 services were impacted from about noon on Thursday 11/12/26 until Friday morning around 6am.
From Microsoft's service desk: https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect
Status as of 11/13 7am: 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.
