title: Shared mailbox between multiple users with MFA enabled - Want no user@email access - Default shared mailbox to users in OWA?
body: <p>I was having users sharing a password to an email account that multiple people needed access to.  Accounts been hacked a couple of times.  I've now converted these mailboxes to shared mailboxes and created each user their own account with MFA enabled and given these users access to shared mailboxes they need.</p>
  <p>I don't want these (or some) users to have their own user@email (only shared@email) and they have to have an email license to access a shared mailbox.</p>
  <p>I also need the shared mailbox to be their default and not user@email when opening Outlook Web if possible.</p>
  <p>I've tried having users &quot;Add shared folder&quot; to their personal Outlook Web, but I can't default the &quot;From&quot; field to the shared mailbox and users keep forgetting to change it when they are really busy which means users are sending from user@email and getting replies back to their user@email accounts instead of shared@email and now users are missing some sales orders.</p>
  <p>I've tried having them use &quot;Open another mailbox&quot; which seems much easier, but some users don't pay attention and just start sending emails from their user@email instead of the shared mailbox.</p>
  <p>Is there a way to have user logins without email accounts, but still be licensed and have the shared mailbox as their default mailbox when they use Outlook Web?  I'm guessing I'd have to deny these users access to send/receive from their own user@email if even possible.</p>
