Latest Message<\/th>\nTitle: Users may experience issues when accessing m365.cloud.microsoft or portal.office.com<\/p>\n

User impact: Users may experience issues when accessing m365.cloud.microsoft or portal.office.com.<\/p>\n

More info: Users were redirected to an error page m365.cloud.microsoft\/error<\/a>. While we were investigating this issue, users could have navigated to m365.cloud.microsoft\/apps or m365.cloud.microsoft\/search as a potential solution in the interim. <\/p>\n

Final status: We identified a code issue within a recent change that led to impact, and we’ve subsequently corrected it to provide mitigation. We confirmed via internal testing, diagnostic data, and customer reports that the issue is resolved. <\/p>\n

Scope of impact: This issue may have potentially impacted any user attempting to access m365.cloud.microsoft<\/a> or portal.office.com. Specifically, users located in Australia, India, Japan, United States, Asia-Pacific, and South America were affected. <\/p>\n

Start time: Wednesday, October 29, 2025, 9:30 PM UTC<\/p>\n

End time: Thursday, October 30, 2025, at 4:21 AM UTC<\/p>\n

Preliminary root cause: A recent code change inadvertently caused issues when users attempted to access m365.cloud.microsoft or portal.office.com. <\/p>\n

Next steps:
– We’re continuing to investigate why this change was not detected earlier during our deployment processes, which will help our development of guardrails to prevent these issues in the future.
– We\u2019re reviewing our incident response procedures to more expediently address and mitigate similar issues more quickly in the future. <\/p>\n

A preliminary post-incident report will be available on the Service Health Dashboard within two business days, followed by a final report to be published five business days after this post’s closure.<\/td>\n<\/tr>\n
