Our alerts have the ability to send from one of your email addresses. This is especially important and needed for customer-facing alerts (i.e. ID181/Service Call Status and ID800/Past Due Invoices), as your customer may elect to reply to this email or, if not recognized by your customer, the email could be sent to their spam.
Below are instructions and reference articles on setting up the needed "Send As" (not "Send on Behalf of" permissions).
If you elect to NOT set up the outbound connector (though we strongly advise to set the outbound connector because using smtp.Office365.com comes with some restrictions. The biggest one is a 30 message per minute rate limit which we can, and likely will, hit very easily. It can cause unexpected results like notifications only being partially delivered, some surveys may not reach your customers, etc. Please set here:
Go to Office 365 ** admin center ** > Users > Active Users.
Choose the the user mailbox you want to give ceojuice permissions to, then click on Edit next to Mailbox permissions.
In the search box under Send as, type the name of the ceojuice user to allow to send send as permissions.
Once you've selected your users, click Save.

Send As permissions can be granted using the Exchange admin center. Navigate to Recipients, then choose the type of recipient you want to grant Send As right for (in this example I am using a shared mailbox called “Help Desk”). Click the Edit button to open the properties of the mailbox.
Select Mailbox Delegation, then click the + button for the Send As permissions and choose who you are granting the permissions to. Click Add then OK, and then Save to complete the task.
Exchange 2007 / 2010:
