Question: Does Unity Connection / Speechview support a cloud based Office 365 / O365 email / end user environment?
Or will Unity Connection support this in the near future and/or what version might support this - Unity Connection v11.5 / v12.x, etc...
My understanding is this will not work due to the fact that CUC will not accept EHLO and O365 cannot be configured to send HELO. Take a look at the following bug. No word on when this will be fixed as of yet.
This is not directly documented but the bug filed has a work around which implies support of SpeechView and CUC, but not the SMTP relay components involved. There are too many SMTP variations for TAC to support, but, all of the ones I have worked with so far work: Ironport, IIS SMTP Server and Symantec Brightmail. Most networks should have an internal SMTP relay for all sorts of notifications from systems out to the internet. You know the ones that blow you up when something's busted. However, external relays can be tricky with all the nefarious SMTP scammers, spammers and bots. If you have a mail filter (ex. Ironport) or external system (ex. Brightmail) then this should be pretty easy as those flows are in place now and only DNS needs to be updated. Cisco was happy to help read the logs and point out issues that we had to fix along the way. Some notes on the differences.
