Previously our client was using Office Online with Exchange 2007 SP1.
Now we have an application which download emails from Exchange directly.
Previously client was using on Outlook Exchange settings, Exchange Url : red002.mail.emea.microsoftonline.com.
So in our application settings we used following URL to connect to exchange server.
Exchange web service : https://red002.mail.emea.microsoftonline.com/ews/Exchange.asmx
Now has shifted to Office 365 with Exchange 2010. Also they have got Exchange Url : DB3PRD0610.mailbox.outlook.com
But now exchange web service 'https://DB3PRD0610.mailbox.outlook.com/ews/Exchange.asmx' is not working.
Also for web portal 'https://dbxprd0610.outlook.com/owa/' this is not working,
Always giving following error: The remote server returned an error: (401) Unauthorized.
Can some body tell which Exchange Web Service URL i should use now.
