I am writing this in hopes of helping others out there.

I recently needed to connect to a Microsoft Exchange box from Domino to retrieve mail. I was not allowed to forward the mail to a Notes mail in database for this purpose. I looked at a few options and settled on Microsoft's EWS services api for java. The version I am using is a bit old as of this writing (ews-java-api-2.1.jar) but it works for what I need. I just need to read incoming messages from a specified mailbox and render them to a web front end in Domino.

there is a tool called EWS Editor that helped me get thecorrect exchange URL. Use this to get all your parameters you are not sure of.

You will need the following jar files:

ews-java-api-2.1.jar

httpclient-4.5.2.jar

httpcore-4.4.4.jar

commons-codec-1.10.jar

commons-io-2.5.jar

commons-lang3-3.4.jar

comons-logging-1.2.jar

joda-time-2.9.4.jar

 

 

Here is my basic code, you can build from this as it creates the connection, authenticates and returns the mail.

          service = new ExchangeService();
          // Provide Crendentials

          service.setCredentials(credentials);
          
       // Set Exchange WebSevice URL
              String sURL="https://yourexchangemailserver/ews/exchange.asmx";
          
          
              
          System.out.println(sURL);
         
           service.setUrl(new URI(sURL));
           // Get five items from mail box
           ItemView view = new ItemView(5);
           System.out.println("setURL");
           // Search Inbox
           FindItemsResults<Item> findResults = service.findItems(WellKnownFolderName.Inbox, view);
           System.out.println("FindItemsResults");
         //iterate thru items
           for (Item item : findResults.getItems()) {
            item.load();
            String subject=item.getSubject();
            //Read Body
            String body = MessageBody.getStringFromMessageBody(item.getBody());
            //System.out.println(subject);
           // System.out.println(body);
            pw.println("<br>" + subject);
            pw.println("<br>" + body);
                
            pw.println("--------------------------------------------");
            //Reading Header
            InternetMessageHeaderCollection headers = item.getInternetMessageHeaders();
            for(InternetMessageHeader header:headers){
             //System.out.println("Header Name: "+header.getName()+" Header Value: "+header.getValue() );
             
         
             //pw.println("Header Name: "+header.getName()+" Header Value: "+header.getValue() );

            }
           }
          

      } catch(Exception e) {
          e.printStackTrace();
       }
   }
}

 

Hope this is a help.
