Exchange 2007 Mail enable User Powershell Quick Form

A couple of weeks okay I had to mail enable (as opposed to create mailboxes) for a bunch of Active Directory accounts in a variety of OU’s in Active Directory. With previous versions of Exchange being able to do this directly from ADUC made this task relative easy and depending on the number of accounts you had to do probably not something that was worth writing a script for. With the loss of this functionality out of ADUC you have to use either a wizard in the Exchange Management Console or do it directly from Powershell. I’m not a fan of the EMC wizards they are there to do a job which they do adequately but are just too time consuming to use for repetitive tasks that aren’t worth writing a larger script to do. So I decided to port the form I had for doing quick mailbox creates to do quick mail enabled's. I wouldn’t say the result was brilliant but in the end once I had the form up I could bang though the accounts I wanted to mail enable resonably quickly (what helped is the external mail address I wanted to mail enable the user for was already in the mail attribute) vs going through the wizard for each user and clicking, cut and paste etc .

The script is similar to a lot of the others I’ve posted before it uses a .net winform to present a user interface to the users. Once you select an OU it runs the Get-User cmdlet to filter and retrieve only the users from that OU selected that aren’t currently mail-enabled or have a mailbox associated with it. This populates the UserName Drop down box. Once a user is selected from the dropdown the other textboxes are populated in the form from the information in the User account (retrieved using the Get-User cmdlet). This then builds a Enable-MailUser cmd line if you edit any of the information in the text boxes that affects the cmdline that will run which you click the mail enable button the cmd is updated as you type. This is achived by hooking into the TextChange event of each of the texboxes. Maybe the form isn’t that impressive but this function is pretty funky and worth giving a check out if you want to build your own little GUI's for your helpdesk users to use (you know all those people who’s eyes glaze over when you try to explain what powershell is).

Because this script requires the Exchange Management Shell Cmdlet's it needs to run from the Exchange Management Shell. If you download the script file from this site you need to right click the file and select unblock from the properties menu to allow the script to be executed.

I’ve put a download copy of this script here the script itself look 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 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
