I've got a customer that has switched to hosted O365 for their email server. This isn't an issue with a 3300 for some reason (different customer and it works). But this customer has a 200ICP, and no matter what we're doing we can't seem to get this to work.
I'm considering sending their IT company a MSL disc to turn up a system and make it a relay. Would this work on the 200 ICP?
