Latest Message<\/th>\nTitle: Some users may be unable to send or receive email from the Outlook mobile app on their Android and iOS devices<\/p>\n

User impact: Users may be unable to send or receive email from the Outlook mobile app on their Android and iOS devices.<\/p>\n

More info: Affected users utilize Hybrid Modern Authentication (HMA).<\/p>\n

Current status: The fix has saturated across 99 percent of the affected environment and we’re continuing to monitor its progress to ensure the deployment completes and remediates impact. We’re expecting that the fix will reach 100% saturation by our next scheduled update.<\/p>\n

Scope of impact: Some users of HMA attempting to send or receive email from the Outlook mobile app on Android and iOS devices may be impacted.<\/p>\n

Start time: Thursday, August 14, 2025, at 7:32 AM UTC<\/p>\n

Root cause: A recent build update introduced a condition where, upon encountering a typical transient failure, an exception is generated for a subset of users that results in the sync job responsible for syncing outbound and inbound mail being placed in a quarantine state, resulting in syncs being delayed for a 12-hour interval.<\/p>\n

Next update by: Friday, September 12, 2025, at 9:00 PM UTC<\/td>\n<\/tr>\n
