Copy / Paste here just in case the original post disappear

1/ General SMTP Relay settings for Office 365

2/ Configuring IIS

1. Create a user with an Exchange Online mailbox

• You can either create the user in your Active Directory, run Directory Synchronization, Activate user with Exchange Online license. (The user must not have an on-premise mailbox)
• Or you can create the user using Microsoft Online Portal or via Microsoft Online Services PowerShell Module and assign the user an Exchange Online license.

2. Configure either the LOB or IIS SMTP Relay server. In this example I am using an IIS SMTP Relay server that other applications can use to send mail:

1. Install IIS onto an internal server, selecting to install the SMTP components
2. Expand the Default SMTP Virtual Server and click the domains node
   1. Right-click Domains and select New > Domain > Remote
   2. Name = *.com and click Finish
3. Double-click the newly created domain
   1. Ensure “Allow incoming mail to be relayed to this domain” is checked
   2. For Forward all mail to smart host, type smtp.office365.com

 

4. Click Outbound Securityand configure the following settings

1. Select Basic Authentication
2. For User, type the user name and password of the Office 365 mailbox user
3. Check the TLS encryption option
4. Click OK
