Is there any chance of seeing office 365 support in the future?
What kind of support would you expect in particular? It’s already possible to use Office 365 for a domain hosted at DreamHost by adding appropriate DNS records to the domain.
Yes, you can add the record manually, but I think that should be great if support a more automatic way to add it as you do with Google Services.
You can add a sort of wizard were you can copy and paste the information from Office 365 site and easily add all the configuration required.
