Looking for your questions on Exchange extensibility for MEC

This blog has been a little quiet over the last month as I've been putting all my efforts into my MEC Talk which is now only a week away, but I should have a number of new posts soon after that.

In addition to this talk I am going to be moderating the Experts Unplugged: Exchange Extensibility session at MEC. If your interested in Exchange extensibility in any way this should be a really good session to attend, as we will be able to discuss exchange extensibility as a whole across EWS, Transport, Apps and Powershell and not just the individual components. The Panel for this session is made up of Subject matter experts from Microsoft who are responsible for designing,building, and directing the future of extensibility in Exchange. So this will be great opportunity for the community to come together and discuss where we are at with extensibility, some of new exciting stuff in SP1 and where we are going in the future. More importantly its your opportunity if you are attending MEC to give some feedback to the panel.

If you aren't able to get to MEC or you can't get to this session and you have a really good question (or piece of feedback) or something you would really like to see in Exchange extensibility. Please Email me glenscales@yahoo.com or post your question as a comment on this blog entry and I'll try to include this in the discussion and get back to you with an answer of some sort. If you are going to attend this session and are a bit shy about asking questions you can also let me know your questions.

If you haven't heard already Exchange 2013 SP1 both (onPrem and Online) has been released bearing extensibility gifts, here are some pre reading links for some of the new SP1 bits and new Exchange Online bits that are worth reading on your way to MEC.

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 Gr...

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 ...

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 ...
