It works for the file provided in test but, does not works for the files i tried to test with
OutlookMessage outlookMessage = new OutlookMessageParser().parseMsg(new File("example.msg"));
System.out.println(outlookMessage.fetchCIDMap().keySet().size()); // this is zero
System.out.println(outlookMessage.fetchTrueAttachments().size()); // this is 1
expecting CIDMap keyset size to 1 as the file has inline image
