I am opening a branch office and need to setup exchange server . Right now in my head office I am using exchange server with domain as @glweststardubai.com. (We are downloading mails using pop collector into our exchange) What i want to know is whether I can configure the exchange with same domain name in branch office. Will it give any problem in sending or downloading mails. ie if any one sends out a mail to head office say "email@example.com" from branch office email firstname.lastname@example.org.
