Adding the From

The first time you send as another email address you will need to configure the From address. When composing an email message click on the "Options" tab and check the box for "Show From". This will add a drop down showing your "From:" address above the To/Cc fields.

Errors

The most common errors are regarding the lack of the SendAs permission. You must be assigned the SendAs permission directly or be a member of a group with SendAs permissions for the address.

  • If you were recently added to a group you may need to wait at least 30 minutes and then sign out and back into your account to have the SendAs right.
  • The From address may be "cached" incorrectly. This is more common with the Outlook Desktop client. The fix is to delete the From address and re-add it.
