Whether it’s an Exchange setup matter or an issue with Outlook?

While opening ‘the Select Names Dialog’ with a view to getting all the members of a specific distribution list, I used to make use of the same code unerringly that I got from msdn. In the case of Outlook 2010, it seems to function accurately on a test server.

But the same does not happen in Outlook 2007 in the environment where I am used to working. The recommendation of Outlook Object Library 12.0 is added to the assignment I am working on. It is, in fact, a COMException. Usually I am used to trying it.

But what happens is that ‘the Select Names Dialog’ simply doesn't demonstrate up either way. I have already thrown the exception at the Outlook.SelectNamesDialog snd = olApp.Session.GetSelectNamesDialog(); line.

From my inquiring, I can’t decide whether it is an issue with security. Is it? Yet the fact is that it does not get to that point where it’s snatching the DL or the members. I am badly in need of fixing the issue.

For your better understanding it is to be noted here that although I have limited administrative rights over the Exchange server, I, if needed, will be able to fine-tune some of the things after taking permission.

Will you please tell me whether it’s an Exchange setup matter or an issue with Outlook? Or it is something else.

Please give me a solution.
