Milind, thanks for the answer.
I checked Exchange Online: today’s email inbox trace does not contain your emails. There are no letters in quarantine. There are no letters in spam or trash either.
Sent trace contains a letter sent to you yesterday with the status “delivered”. Subject of the email: Error in the search, sent from the same email by which the one-time code was requested today. Also sent trace contains a letter sent to you today with the subject: Test 14:09, but from the email address of another employee.
Please clarify at what time your mail server sent me letters?
