I have a customer with multiple users, they have two emails accounts on two differents domains.
One is managed by Office365 : Teams / Calendar, example : @my-business.com Second is for "secure" communication, exemple : @my-secure-email.com
The second one is really not used very often but the emails sent or received must absolutely not go on Office365 (legal reason)
I want to force user to send emails to *[email protected] with second account.
With "on-send Feature" i think i can "block" emails but ideally it should be possible to dynamically change the account used in Outlook according to the recipient's address ?
EDIT to clarify :
Is it possible to change sender account with office-js and "on sender" feature on office365 ?
Is it possible to change sender account direclty in Outlook for Windows based on recipient address ?
Thanks

No, it is not possible. OfficeJS doesn't provide anything for that.

Yes, you can choose the sender's account in Outlook manually or by using a VSTO add-in instead. The MailItem.SendUsingAccount property is available in the Outlook object model (available for VBA macros and COM based add-ins). The property allows setting an Account object that represents the account under which the MailItem is to be sent.
But web add-ins work under the context of currently selected item only (or in case of UI-less add-ins what they activated for) and don't provide access to application-wide features like choosing email account to send from.
