Trouble viewing email header in MS Defender under mail explorer?

Hello,

Has anyone encounter issue trying open or view email header in MS Defender under mail explorer?  This only happens on messages that are in users mailbox.  I get a n error that says "Message details not found. When a message is soft deleted or hard deleted by the user or the admin, its details no longer exist in the mailbox or server".  I don't get this on messages that been flag with alert only on normal messages that are in users mailbox and the message is still in my mailbox.

Thanks!
