POX based Autodiscover clients and the Exchange 2013/Office365 preview

The big thing is the past week or so has been the release of the Exchange 2013 preview and in the cloud world the Office365 (Exchange Online 2013) preview. One of the new things in the Auto-discover response if your using one of these is the EXHTTP node that gets returned eg


I haven't quite found where this node is documented yet but if your creating Outlook Anywhere Profiles programmatically against the Office365 preview then the Server info from this node is important for building a Outlook Anywhere profile.  If your using your own POX based Auto-discover client you won't get access to this new information unless you set the UserAgent so the request looks likes its coming from Outlook.
eg

  1. String snServerName = @"https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml";  
  2. String OAProxy = "";  
  3. String OAProxy1 = "";  
  4. String ProxyCertName = "";  
  5. String ProxyCertName1 = "";  
  6. String ProfileName = "";  
  7. String InternalServerName = "";  
  8. //Do AutoDiscover  
  9.   
  10. String auDisXML = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Autodiscover xmlns=\"http://schemas.microsoft.com/exchange/autodiscover/outlook/requestschema/2006\"><Request>" +

  13.       "</Request>" +  
  14.       "</Autodiscover>";  
  15. System.Net.HttpWebRequest adAutoDiscoRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(snServerName);  
  16. adAutoDiscoRequest.CookieContainer = new CookieContainer();

  26. rsRequestStream.Write(bytes, 0, bytes.Length);  
  27. rsRequestStream.Close();  
  28. adAutoDiscoRequest.AllowAutoRedirect = false;  
  29. WebResponse adResponse = adAutoDiscoRequest.GetResponse();

  43. }  
  44. adResponse = adAutoDiscoRequest.GetResponse();

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Graph is limited to a m

Sending a Message in Exchange Online via REST from an Arduino MKR1000

This is part 2 of my MKR1000 article, in this previous post  I looked at sending a Message via EWS using Basic Authentication.  In this Post I'll look at using the new Outlook REST API  which requires using OAuth authentication to get an Access Token. The prerequisites for this sketch are the same as in the other post with the addition of the ArduinoJson library  https://github.com/bblanchon/ArduinoJson  which is used to parse the Authentication Results to extract the Access Token. Also the SSL certificates for the login.windows.net  and outlook.office365.com need to be uploaded to the devices using the wifi101 Firmware updater. To use Token Authentication you need to register an Application in Azure https://msdn.microsoft.com/en-us/office/office365/howto/add-common-consent-manually  with the Mail.Send permission. The application should be a Native Client app that use the Out of Band Callback urn:ietf:wg:oauth:2.0:oob. You need to authorize it in you tenant (eg build a small ap

How to test SMTP using Opportunistic TLS with Powershell and grab the public certificate a SMTP server is using

Most email services these day employ Opportunistic TLS when trying to send Messages which means that wherever possible the Messages will be encrypted rather then the plain text legacy of SMTP.  This method was defined in RFC 3207 "SMTP Service Extension for Secure SMTP over Transport Layer Security" and  there's a quite a good explanation of Opportunistic TLS on Wikipedia  https://en.wikipedia.org/wiki/Opportunistic_TLS .  This is used for both Server to Server (eg MTA to MTA) and Client to server (Eg a Message client like Outlook which acts as a MSA) the later being generally Authenticated. Basically it allows you to have a normal plain text SMTP conversation that is then upgraded to TLS using the STARTTLS verb. Not all servers will support this verb so if its not supported then a message is just sent as Plain text. TLS relies on PKI certificates and the administrative issue s that come around certificate management like expired certificates which is why I wrote th
