Hello everyone,

[[Actual Situation]]

We are using Office 365 as mail provider and Rackspace as hosting provider.

In Office 365 we have all our employees with email address name@mycompany.com

Also we are using 10-12 generic email addresses as sales@mycompany.com, marketing@mycompany.com, invoice@...., orders@.... and so on... At this moment all these mails are on Office 365 as shared mailboxes which means that are not with user and pass.

Also we can make mailboxes on Rackspace but we've didn't used any till now.

[[What we want]]

We are looking for a solution in which we should not add new users to Office 365 in order to:

1. use marketing@mycompany.com to send email newsletters and to not be limited by a mail SMTP (in the database there are about 2500 - 5000 potential customers with email addresses). We take in consideration to use a 3rd party app in order to work with this. How we can setup this email in the best way to work with Odoo Email Newsletter and to not have delivery issues?

2. How we  can  setup sales@mycompany.com to receive leads in Odoo?

3. How we can setup the MX in order to work both with Office 365 and Rackspace mail in the same time?

Any feedback it's highly appreciated.

Also if you have resources on how to use Office 365 with Odoo i will really appreciate.

Best regards.
