Active Directory to hCard Web Service

I’ve been playing around further with microformats this week and I decided to come up with something practical I could use to transfer contact information between apps. As a starting point because most of my contact information is stored in active directory I wanted something that would be able to convert an Active Directory user object into a hCard contact. As a conduit I decided to go with a WebService as this was something that could be easily integrated into everything from a script to a fully blown windows application. There are some good tools already out there that can deal with the information once its in hCard form like Tails for Firefox or Technorati Contacts Feed Service .

The webservice itself is pretty basic it takes the useraccount name as an input parameter for which account you want to convert and then it returns a XML document that contains the user account information that has been extracted from various active directory attributes using the System.directoryservice namespace and then formatted as a hcard using the XMLtextwriter. Because the hcard format is based on the vcard format matching the information from AD wasn’t that hard (although a little time consuming) the only thing that took at little time to work out was mapping the office attribute to the extended-address.

What can you do with hcard’s probably the one of the best examples at the moment in the Live clipboard. Its still an emerging standard but the coolest thing about it is once you have the contact information in a hcard format its very easy to work with as compared to a standard vcard.

I put a downloadable copy of the code here the code itself looks like

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...

Exporting and Uploading Mailbox Items using Exchange Web Services using the new ExportItems and UploadItems operations in Exchange 2010 SP1

Two new EWS Operations ExportItems and UploadItems where introduced in Exchange 2010 SP1 that allowed you to do a number of useful things that where previously not possible using Exchange Web Services. Any object that Exchange stores is basically a collection of properties for example a message object is a collection of Message properties, Recipient properties and Attachment properties with a few meta properties that describe the underlying storage thrown in. Normally when using EWS you can access these properties in a number of a ways eg one example is using the strongly type objects such as emailmessage that presents the underlying properties in an intuitive way that's easy to use. Another way is using Extended Properties to access the underlying properties directly. However previously in EWS there was no method to access every property of a message hence there is no way to export or import an item and maintain full fidelity of every property on that item (you could export the...
