Recently, I faced up with strange behaviour of
ResolveName method of
ExchangeService class. This method should finds and resolves contacts in a specified user’s Contacts folder and the Global Address List (GAL).
Method is called in the following way:
var emailAddress = @"firstname.lastname@example.org";
var resolutions = service.ResolveName(emailAddress);
if (resolutions != null && resolutions.Count > 0)
service is the [correctly] initiated variable of type
In the following instances
ResolveName method returns the empty list:
1. Email address is incorrect;
user‘s account is hidden from Exchange address list.
But one of the customers has Exchange installation and/or ActiveDirectory settings such that
ResolveName method returns the empty list for correct non-hidden mail address. Unfortunately, I didn’t find any reasons of such behaviour.
1. All used IP-addresses, names of servers, workstations, domains, are fictional and are used exclusively as a demonstration only.
2. Information is provided «AS IS».
