Hello BHW I couldn't find a better category to post in. Feel free to move if necessary. I was looking into Microsoft Exchange Online for hosting my email accounts. I want the active synchronization. I need a hosted solution that will allow me to synchronize my email AND calendar across devices... I need to host about 5 different domains' email addresses. This is possible to an extent- with Shared Mailboxes. With Shared Mailboxes, I can have separate mailboxes that I(only) admin, that have full separate boxes instead of just an Alias that forwards emails to my main email address. Long story short, Microsoft Exchange has an issue with creating additional "Shared Mailboxes" with the same name. So if I have [email protected], I can NOT create any other shared mailbox with "name"@* More examples. I create [email protected], I can NOT create [email protected], or [email protected], etc... It has something to do with what Exchange does in the backend. Whenever you create a shared mailbox with any name(ex. carl), that automatically creates a *Unique* windows id with that name at the main domain. So even if I created [email protected], in the backend it also creates [email protected] So if I later tried to create "Carl"@AnyOfMyDomains.com, it will NOT allow this. It will say a windows live id is already created with that name(or something like that) .................. What other Email hosting providers offer QUALITY hosting, AND the possibilty of synchronizing my email and calendar???? It must have global spam rules I can admin. It must be able to fullfill my need mentioned above. I contacted Google Apps, and they will followup with me. But I am thinking this may not work because they license some of Microsoft's technology for some of the backend stuff. We'll see. I am on Shared Hosting. I want a quality solution that can scale with me. I currently will only be send/receiving a VERY small amount of mail. What else is out there???
