Hi everybody,
When using the SMTP Gateway of Exchange Online (authenticated, TLS encrypted, and so on), does it keep each sent e-mail into the "Sent Items" folder of the mailbox used to relay?
For example: you use the Exchange Online SMTP Gateway from an all-in-one device, it uses a full paying Exchange Online Plan 1 subscription (mandatory to authenticate).
Then you connect to the same account using OWA.
Do you see a copy of e-mails sent from the AIO?
And if the answer "no", have you successfully implemented a workaround:)?
Thank you!
