How to get company by user email from Active Directory?

I use Microsoft.Exchange.WebServices.

 private const ExchangeVersion ExchangeVersion = Microsoft.Exchange.WebServices.Data.ExchangeVersion.Exchange2007_SP1;
 //...
 _exchangeService = new ExchangeService(ExchangeVersion);
 var collection = _exchangeService.ResolveName(userEmail);

It gives me one object with MailBox item (with proper email address) and Contact = null.

Answer 1

ResolveName() returns NameResolutionCollection, NameResolution has a Contact property, the Contact property has collection of Companies.
