Latest Message<\/th>\nTitle: Users may be unable to view the body of edited Exchange Online email messages from the Sent folder <\/p>\n

User impact: Users may have been unable to view the body of edited Exchange Online email messages from the Sent folder. <\/p>\n

More info: When a user opened and edited an email message in the draft folder, sent it, and then viewed it from their sent folder, the edited portion may have appeared blank in the message preview.<\/p>\n

Impact only occurred for users utilizing the “Show email as individual messages” Message organization setting. While we worked on mitigating this issue, users could utilize the “Show email grouped by conversation” message organization setting to avoid this issue. <\/p>\n

Final status: We’ve completed the deployment of our fix and confirmed through testing with a subset of affected users that the impact has been remediated. <\/p>\n

Scope of impact: Users attempting to view the body of edited Exchange Online email messages from the Sent folder may have been impacted. <\/p>\n

Start time: Wednesday, April 15, 2026, at 10:36 AM UTC <\/p>\n

End time: Friday, June 05, 2026, at 7:18 PM UTC <\/p>\n

Root cause: A code issue occurred when an email message was saved to drafts and it created a local copy. When a user edited the email message in drafts, sent it, and then viewed the email message from their sent folder, it attempted to reference the stale local copy instead of the edited version. As a result, the attempt to fetch the body failed and caused impact. <\/p>\n

Next steps: – We’re reviewing the offending code issue to determine how it was introduced into the service, so that we can prevent similar instances of impact from occurring in the future. <\/p>\n

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