I am using O365 Outlook (imap) and request" read receipt", all my other account work fine like this. However my Sky yahoo mail account removes the sent email from the sent folder after I read the "read receipt".
After sending email between my accounts I watched the sent email disappear as soon as I read the "read reciept", however it does not move to trash or any other folder. If I remove "read receipt" requirement the sent email stays in the sent folder.
Sent Email disapear after Reading Read Reciept
