Latest Message<\/th>\nTitle: Admins may have been unable to access the Exchange admin center (EAC)<\/p>\n

User impact: Admins may have been unable to access the Exchange admin center (EAC).<\/p>\n

More info: Admins may have received the following error “HTTP Error 500”.<\/p>\n

Final status: During the rollout of a new mitigation strategy for the issue resolved on Wednesday, April 9, 2025, communicated under EX1051697, we deployed a different mitigation strategy to a small amount of infrastructure in the North America region. The new mitigation strategy did not have the expected results, and caused impact to reoccur. We have reverted the service to use the previous remediation strategy and confirmed that the impact is no longer occurring.<\/p>\n

Scope of impact: This issue could have affected any admin accessing the Exchange admin center located in the North America region.<\/p>\n

Start time: Thursday, April 10, 2025, at 10:40 AM UTC<\/p>\n

End time: Thursday, April 10, 2025, at 11:23 AM UTC<\/p>\n

Preliminary root cause: An authentication issue within a specific URL path caused HTTP 500 errors resulting in impact.<\/p>\n

Next steps:
– We’re reassessing our service monitoring of this impact scenario to implement improvements for detecting similar events and reduce the time to identify and address this type of impact.<\/p>\n

This is the final update for the event. <\/td>\n<\/tr>\n
