Hosted exchange is fairly cheap and seems to be making sense for small business at the moment, but as mentioned above what is wrong with A N Other POP3/IMAP service?
If you go with Hosted exchange have a look at CobWeb. They seem to offer a decent service at an ok price point.
But - if i get your system right - you pay a couple of £ per email address? how does that work when mail services/web hosting with another provider etc?
Not being able to host our own servers has put me down a route that i have never tried, of outsourcing some of my ICT.
google apps all the way, there is not way any crappy outfit is going to be more secure than google
£35 per mail box per year, 25gb storage, imap, full contact and cal sync to outlook and mobile devices, web mail
if you have a hosted exchange box you are relying on a single (though probably virtual) machine to be workign correctly, with gmail as long as the multi billion $ data center is not struck by a nuke your service will be up...
It will probably work out that way,
My question is why you dont run a local exchange server in house, so people on site get normal outlook access and people offsite can use either outlook anywhere or Webmail?
