Never tested.ģ.6 - Validation - I recommend testing with 1 email address that has an Office license and 1 email address of those 15 examples that only exist on your "legacy" server.ģ.7 - If the connection to the server fails, it is probably the address that is wrong or the TLS security settings. If your server doesn't have a security certificate, you need to test that without TLS the connection will work correctly. Currently, even shared servers like Hostgator offer free SSL, so if your server has a certificate, you won't have major problems with this step. It's just for easy identification.,ģ.3 - Connector Usage > Use only for emails sent to all accepted domains in your organization.ģ.4 - Routing > Put the IP or the FQN of your private email server.ģ.5 - Security restrictions > I recommend using TLS issued by a trusted CA. We do this with a Connector in the next step.ģ - Still in the Exchange Administration Center", go to "E-mail flow"/"Connectors" and follow these instructions.ģ.1 - Email flow scenario > From: Office 365 > To: Your organization's email serverģ.2 - Name and Description > Anything that identifies your remote email server. But we still need to warn Exchange that, since it won't validate ALL email accounts in the same place, where it should validate them if they don't exist in its scope. In this way, we're telling Microsoft not to assume that it "owns" all of my company's email account management.Ģ-3 - Okay. It may be translated differently in your language, but it will be there.Ģ.1 - Select your private domain, that is, the domain you already had when you subscribed to Office 365.Ģ.2 - You must choose that this domain is used for "Internal Relay" and NOT "Authoritative" which is the default. Let's fix this.Ģ - The first thing you need to do is go to the "Exchange Administration Center" and access "E-mail flow"/"Accepted Domains". Let's go.ġ.2 - Well, at this point, if I send external email to any of the 15 email accounts that aren't licensed, I'll get an "invalid recipient" error or something. Using the wizard or doing the setup exactly as suggested should suffice.ġ.1 - At this time, only the 5 licensed users will receive and send email normally. In summary: All 20 users have email, 5 will be fully managed by Exchange Online, and 15 will not.ġ - Carry out all the authorization of ownership of your domain normally, that is, add/modify the DNS entries on your server to use MS Exchange Online as the incoming server. The other 15 employees will use the mechanisms that already existed to send and receive emails, be it pop3, imap or whatever, pointing to their "legacy" server. This means you will be able to access them online from any other device.Only 5 employees will be licensed for Office 365 and will access email through Outlook 365.
