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 have experienced delays in loading images and attachments in Exchange Online email messages.<\/p>\n

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

Final status: We\u2019ve confirmed that our fix deployment has reached the vast majority of the affected environment and determined from monitoring service telemetry that this issue is no longer occurring. <\/p>\n

Scope of impact: Some users may have experienced delays in loading images and attachments in Exchange Online email messages.<\/p>\n

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

End time: Thursday, November 13, 2025, at 6:15 PM UTC<\/p>\n

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

Next steps:
– We\u2019re reviewing our validation and updating procedures to better detect and prevent issues like this prior to deployment in the future.<\/p>\n

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