Thank you for explaining the two methods of authentication.
That the web server was restarted after Outlook connected can be excluded. In my case the web server is up since installation of splendidCRM. There is however another phenomenon that puzzles me and may contribute to get the right picture. Each time I start Outlook I go to the "splendidCRM Settings" within Outlook to check, if I can connect to our server. To do this, I simply press "Test" in the "Authentication Options". This will always fail the first time, i.e. without changing anything in the window. After retyping my password it will always succeed. In the case of failure I get the following message:
Boolean Connect() Line 379.
System.Web.Service.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Invalid username and/or password
at SplendidCRM.soap.LoginUser(String sUSER_NAME, String sPASSWORD) in C:\Web.net\SplendidCRM2\soap.asmx.cs:line 604
at SplendidCRM.soap.create_session(String user_name, String password) in C:\Web.net\SplendidCRM2\soap.asmx.cs:line 620
--- End of innter exception stack trace ---
This means the password has not been stored. This behaviour can be repeated within one Outlook session as many times as I want. Each time I close the "splendidCRM Settings" window, the password seems to be lost. Is this behaviour by design?
