Latest Message<\/th>\nTitle: Some users may experience delays in loading images and attachments in Exchange Online email messages<\/p>\n

User impact: Users may experience delays in loading images and attachments in Exchange Online email messages.<\/p>\n

More info: Delays may be up to ten seconds. Some users’ signature add-in images may also be affected.<\/p>\n

Current status: Our internal service telemetry continues to report improved service performance as our reversion removes the offending code regression and repairs the affected service infrastructure. Our updated reversion timelines estimates that the process will have completed and that impact will be remediated by our next scheduled communication update.<\/p>\n

Scope of impact: Some users may experience delays in loading images and attachments in Exchange Online email messages. This section may be updated as our investigation continues.<\/p>\n

Start time: Monday, November 3, 2025, at 4:31 PM UTC<\/p>\n

Root cause: A recent update to an authentication component of attachment logging introduced a regression which is causing the portion of service infrastructure responsible for loading signature add-in images to operate in a suboptimal state.<\/p>\n

Next update by: Thursday, November 13, 2025, at 8:00 PM UTC<\/td>\n<\/tr>\n
