Latest Message<\/th>\nTitle: Some users may be unable to send or receive email messages using connection methods utilizing Exchange Web Services API<\/p>\n

User impact: Users may be unable to send or receive emails using connection methods utilizing Exchange Web Services (EWS) API.<\/p>\n

More info: This specifically impacts users with streaming notifications enabled for Exchange Online who are also using connection methods that utilize the Exchange Web Services (EWS) API, including, but not limited, to legacy Outlook for Mac.<\/p>\n

Current status: We’ve completed the validation of our fix and initiated its deployment in the affected environment. Our monitoring indicates that the fix’s deployment is currently 10 percent complete. We’ll provide an estimated resolution timeline once available. In parallel, our continued assessment of the underlying root cause of this issue has revealed that impact is specific to users of streaming notifications in Exchange Online whose connection methods utilize the EWS API.<\/p>\n

Scope of impact: This problem may impact some users who are served through the affected infrastructure that are attempting to send or receive email messages using any connection method that utilizes the EWS API.<\/p>\n

Start time: Tuesday, December 12, 2023, at 8:47 AM UTC<\/p>\n

Root cause: A code regression within a portion of our service infrastructure is causing streaming notification responses to return IDs in legacy format regardless of the request version ingested, which is resulting in impact for users of any connection method that utilizes the EWS API, which is preventing email messages from being sent or received.<\/p>\n
