Imap in O365
Hello, We're currently in hybrid mode with O365 and AD connect, I have a question regarding imap with O365. If we have an application on premise that will need to use imap to send/receive email...
Perfect, that is the answer I was looking for. It would be outbound from on-premise to exchange online for both imap and smtp. Any documentation that would state this that you know of? Also if those ip address ranges for o365 would change at all?
Thanks!
