Hi
When you share shared mailbox via permissions, you have the option to copy sent emails to shared mailbox's Sent Mail folder.
But when you have an mailbox with license (exchange online p1) and you share the mailbox via permissions (meaning you do not add the mailbox account to outlook using password), you do not have the option in mailbox settings to copy all sent emails to that mailbox Sent Mail folder. So when a user has received permissions to use that licensed mailbox via permissions (Not via password), all mails sent by that user on behalf of that mailbox, goes to that users Sent Mail folder.
How do we get all mails sent, on behalf of this lisensed mailbox shared via permissions, get copied also to the Sent Mail folder of this licensed mailbox?
