Microsoft Technet article "Move Exchange Server mailboxes and settings for Windows SBS 2011 Standard Migration" contains a note "Global Mailboxes are not supported in Windows SBS2011 standard. Instead you can map a POP3 account to a group that is enabled to send and receive email in Windows SBS2011 Standard." Yet it does not seem possible to do so. I have an email-enabled Group in AD called Sales which was migrated across from my old SBS2003 server. Group Type is Distribution and Scope is Universal (thought I've tried it at Domain Local and Global also to no avail); In EMC it shows up under the Distribution Groups within Recipient Configuration: properties show it members and its email address. In the Email Addresses tab its default SMTP address is sales@mydomain.com and, taking ideas from some forums I searched, I tried adding an email address "sales@my-internal-domain.local" to no avail. An X400 entry also exists which I assume was migrated from the old server. Yet in the SBS Console/ POP3 Connector Properties, when I set up the appropriate POP connector to download the sales@ email from the hosting company, I am not offered the group in the drop-down list in the bottom box labelled "Windows SBS Email Account": only SBS users show up, not Groups. I tried fiddling in the SBS console a bit: On attempting to create a group called Sales it tells me it already exists (which it does in AD but not in the list in SBS under Gropus). So I'm stuck.
