we have a client that hosts their email somewhere else, but needs to sync their contacts and calendars via exchange. So it would be great to connect them to an exchange server that we have, but to only use it for the contacts and calendars.  We DO have them set up and calendars and contacts are syncing as planned. But the setup forces them to also have superflous  InBoxes in their Mail section that they do not need. Since the client is not technical it is very confusing to them. So we would love to deactivate the mail service on that particular exchange account and leave the Conctacts and Calendars syncing. Unfortunately,I don't think there is an ActiveSynclike implementation for desktops.

Hopefully I was clear on this.  

Thanks so much in advance for anyone who has any thoughts on this, even if it's not possible.  If it's not - I would suggest this as a feature to implement. 

Oh yes - We're working on Outlook for Mac.

Thank You!
