Microsoft on Friday was still struggling to restore service to millions of Outlook and Exchange email users more than 18 hours after its servers crashed and became unavailable.

In an update on Microsoft’s Service Health Status page Friday morning, the company did not explain what triggered the catastrophic outage but said that it did not suspect a cyberattack or other foul play.

“At this time, we have no evidence of malicious activity associated with this incident,” the company said in the update at 6:11 a.m. ET on Nov. 13. “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.”
