Unable To Send Email From Office 365 Shared Mailbox

Had a customer and the newer employee was getting a error that they didn’t have permission to send email from a shared mailbox.  Here is how we were able to resolve this.

  • Log into the Office 365 account with the Admin credentials
  • Under “Groups” go to “Shared Mailboxes”
  • Click on the mailbox to open it’s properties
  • Under the “Members” section click “Customize Permissions”
  • Under the “Send as” section click “Edit”
  • Click “Add Permissions” and check the user you need to add and click “Save”.

Let us know if this helped you…
