ERROR on START of eM on Windows 7 Professional

Crashing eM Client
1

Hello everybody, 
i run eM on Windows 7 Professional in a corporate network. 

I use eXchange.

Well, the problem is when eM starts. It shows a window that says: 
“An error occoured, the application will be closed.” After that will appear an alert that inform me that the Report sending has failed, Proxy authentication required.

Here is the bug file:

Failed to send:Richiesta non riuscita con codice di stato HTTP 407: Proxy Authentication Required.eM Client (6.0.20617.0)

The problem persist on the old PCs of corporate ( i tried it on 4 PC). We recently bought new computers and in these it doesn’t happen.

Is important to know that the problem exists on the old PCs only while i use eXchange. If i use others mail like gmail or others it doesn’t happen.

What could be the problem?

Thank you,
Best regards

Hi, are you using proxy on this computer?
Possibly setup in Internet explorer? If you’re using proxy and using windows credentials we have a workaround for using proxy with eM client.

Thank you,
Paul.

Hi Paul, yes we use proxy.
The settings of IExplorer are the same on the both PCs, the older and the newer.

Why the problem doesn’t exist in all PCs?

So, please could you give me the workaround?

Thank you,
Best regards.

Hi again Michael, are you using windows credentials for authentication?
If so, can you please send me an email to [email protected] with a reference link to this forum topic, I’ll send you the workaround configuration file attached in my reply.

Thank you,
Paul.
