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 behaviour 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\u2019re analyzing reported behaviour to better understand the issue and to determine the cause of impact. <\/p>\n

Scope of impact: Impact is specific to some users attempting to view draft email messages in Exchange Online. <\/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
