Hi ashishsaluja ,- Please check the inbox rules in your inbox- Please let your Exchange administrator start a message trace regarding your coming emails (https://admin.exchange.microsoft.com &gt; Mail flow &gt; Message trace). Configured transport rules can be the cause of the issue.&nbsp;&nbsp;&nbsp;

Maybe that the email is being placed within a "conversation", so is there rather than in timestamp order.

Some of the mails were going into quarantine but now it is fine. The other problem now is that the reciepents are not getting the email. it shows in their mail box and then disappears

That some emails were being quarantined on your system indicated that you were being targeted, or at least being sent malware.So it may well be that at least one of the attempts was successful, andyour system has been got-at.With the result that the emails you are sending may be infected.So the recipients systems are quarantining them, or just deleted if that is what their system is set to do.Or their ISP is detecting the inappropriate content and either putting them in the ISP (IMAP) Spam, or Junk folder (probably with a 30 day retention before they get deleted, or just deleting them as it finds them.That the emails shows for a short period in their emails indicates their PC has some anti-malware processing set - maybe whatever they have installed to help protect their system, or built-in actions associated with Windows security, or Outlook settings.I would start by using a browser based app to view your emails and see if that shows the wanted emails, or some are missing.Then, maybe doing a full scan with your protection app,As well as asking those with missing emails to check if their, or their ISP's systems are finding malware, or what MS deem "UNSAFE" content.If you have a "Sig" block it may be that there is something in that.and, from experience ISP checking may be identifying innocuous entries as malware, or -for those not getting the email at all, you or your ISP may have been blacklisted as a (now known) malware source.

ashishsaluja&nbsp;Similar problem. Emails come into Inbox, disappear in 60 minutes to three hours. Vanish right before your eyes. No filters in place. No rules. No conversations. No mobile app or desktop app. Happens viewing mail in web browser. Looks very "server side" to me. Happens to Inbox and Sent items, but not Drafts. Items are not found in Deleted Items or in Archive. I sent up a new rule to copy incoming Inbox items to a new subfolder. Items in subfolder stay, items in Inbox vanish. Message trace indicates emails are received. Changed password, enabled MFA, forced all sessions to log out, problem persists.
