Exception with Exchange Mail


I am getting below exception often when I try to read mails using Exchange mail. Some times No exception and able to see the mails retrieved.

Microsoft.Exchange.WebServices.Data.ServiceRequestException: The request failed. The remote server returned an error: (407) Proxy Authentication Required.

Please Let me know If u have any solution for this to avoid issue permanently

Hi @KavithaPramod
Does any suggestion from the below thread help you:

Hi thank u

But the link you provided is about to connect with orchistrator from community version of studio…

I have same error but scenario is different that too not getting always…

Do u think same solution will work ?

Use direct Exchange URL instead of Auto discover. Also provide User name and Password for authentication. This should resolve this error…

I am using Exchange URL like https://mail.abc.com and not using auto discover property. Username and password are given for connection.

Still facing the issue.

But this is not an Exchange URL. Exchange server URL will end with asmx extension. Please try to use SMTP instead to perform your email activity,

Can you share me the URL format.

I am using above format and able to read mails some times
