Error Messages
Error: Transport error 401 Error: Anonymous Request Disallowed
Steps to Reproduce
- Create an Appointment in Pega Sales Automation and synchronize the it with MS Exchange.
- Create an impersonation account on the Exchange with impersonation privileges for all the users (who manage appointments in Sales Automation).
- Maintain the impersonated account in the EWS_Integration_AuthProfile Authentication Profile.
- Enter the user name and password in the EWS_Integration_AuthProfile in the Designer Studio (after setting up the impersonation account).
- Fill out an Appointment in the Sales Force Automation (SFA) application.
- Create the Appointment and click the Send button.
Root Cause
The out-of-the-box EWS_Integration_AuthProfile Authentication Profile was pre-configured with Basic Authentication. A new Authentication Profile must be created using the NTLM option as the Exchange service made use of NTLM authentication.
Resolution
Perform the following local-change to create a new Authentication Profile with name EWS_Integration_AuthProfile and select the Type as NTLM.
