New Outlook missing sended message
In new outlook (in browser and also in desktop app) is missing mail message which was sended at 11:34, 7.6.2026. I see this message only in Message Tracing in Exchange, but in outlook nothing, is mis...
Since the message appears in Exchange Message Trace, it was successfully sent, so this is likely a mailbox or Outlook synchronization issue rather than a delivery problem.
A few things to check:
Verify you're viewing the correct Sent Items folder (especially if you have multiple accounts or shared mailboxes).
If Send As or Send on Behalf Of permissions are being used, check whether the sent copy is being saved in the delegate's Sent Items instead.
Open the mailbox in Outlook on the web to see if the message appears there. If it's missing everywhere except Message Trace, an Exchange admin should check mailbox auditing or retention rules to determine what happened to the item.
