shared emailboxes

[TrevorG]

SO under my M365 tenant I setup of some shared exchange mailboxes. But as a member of that grounp how do send new emails from a sharerd box as shared@youdomain.com. I see that you can reply but I don't see how to start a new email from that shared email.

First of all, what kind of object are you talking about? Shared mailboxes are detailed here: https://docs.microsoft.com/en-us/exchange/collaboration-exo/shared-mailboxes

Groups are detailed here: https://support.microsoft.com/en-us/office/learn-about-microsoft-365-groups-b565caa1-5c40-40ef-9915-...

Both require you to have Send As permissions in order to send messages using the "shared" email address. Once permissions have been granted, toggle the visibility of the From box (in Outlook this is done under Option in the compose new message window, in OWA it's under the ... menu), then select the shared address and send the message.

It is a shared mailbox not a group. If you add users to the shared box shouldn't that give you permission automatically?

this is an interesting note in the link you sent.

The Full Access permission allows a user to open the mailbox as well as create and modify items in it. The Send As permission allows anyone other than the mailbox owner to send email from this shared mailbox. Both permissions are required for successful shared mailbox operation.

No it doesnt give you permissions automatically, you need to add them.

@TrevorGNot quite, as @Vasil Michev has pointed out, each permission does a specific task, send as does exactly that sends as but doesn't have full permission. You need to scope out what each member needs to be able to do before assigning permissions.
