do i need to buy exchange connector for exchange server 2007 ?

no, but have a look to this site for pricing and licensing http://www.microsoft.com/exchange/en-us/how-to-buy.aspxVincenzo MCTS, MCTIP Server 2008 | MCTS Exchange 2010 | WatchGuard Firewall Security Professional

What do you mean, that means nothing to me. Expalin your question in more details, maybe include a scenario? Exchange 2007 has a few connectors built in which you dont need to buy.Sukh

Hi, No, you don’t need to buy any connector for Exchange 2007. By default, after we install Exchange server 2007, there is no send connector but there will be two receive connectors created automatically, one is client receive connector, another is server receive connector. You can create a send connector by the following steps: Open EMC->Organization Configuration->Hub Transport, click ‘New Send Connector’ in the right Actions For more information, you can refer to the article ‘Managing Connectors’ : http://technet.microsoft.com/en-us/library/bb125128(EXCHG.80).aspx Hope this helps.
