Latest Message<\/th>\nTitle: Some users may see older draft email messages appear as recently modified in Exchange Online <\/p>\n

User impact: Users may see older draft email messages appear as recently modified in Exchange Online. <\/p>\n

More info: Users may notice that previously created draft email messages appear with a recent modification date, even when no visible changes have been made. This behavior can affect multiple draft items, where older drafts appear as if they were modified recently, leading to confusion when trying to determine when a draft was originally created or last edited. <\/p>\n

Current status: We\u2019ve confirmed that 90 percent of the deployment has saturated across the affected environments, and some users may experience alleviation as saturation progresses. We\u2019re continuing to monitor service behavior while the mitigation rollout continues and investigating inconsistencies affecting a subset of traffic to determine an alternate approach that fully addresses the issue, which will help us ensure all affected users receive the fix. <\/p>\n

Scope of impact: Some users attempting to view draft email messages in Exchange Online may be impacted.<\/p>\n

Root cause: Annotation-only updates performed by the specific workload is incorrectly updating the LastModificationTime property on draft email messages, causing draft email messages to be incorrectly updated and resulting in older drafts appearing as recently modified in users\u2019 mailboxes. <\/p>\n
