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 Gr...

EWS-FAI Module for browsing and updating Exchange Folder Associated Items from PowerShell

Folder Associated Items are hidden Items in Exchange Mailbox folders that are commonly used to hold configuration settings for various Mailbox Clients and services that use Mailboxes. Some common examples of FAI's are Categories,OWA Signatures and WorkHours there is some more detailed documentation in the https://msdn.microsoft.com/en-us/library/cc463899(v=exchg.80).aspx protocol document. In EWS these configuration items can be accessed via the UserConfiguration operation https://msdn.microsoft.com/en-us/library/office/dd899439(v=exchg.150).aspx which will give you access to either the RoamingDictionary, XMLStream or BinaryStream data properties that holds the configuration depending on what type of FAI data is being stored. I've written a number of scripts over the years that target particular FAI's (eg this one that reads the workhours  http://gsexdev.blogspot.com.au/2015/11/finding-timezone-being-used-in-mailbox.html is a good example ) but I didn't have a gene...

Sending a MimeMessage via the Microsoft Graph using the Graph SDK, MimeKit and MSAL

One of the new features added to the Microsoft Graph recently was the ability to create and send Mime Messages (you have been able to get Message as Mime for a while). This is useful in a number of different scenarios especially when trying to create a Message with inline Images which has historically been hard to do with both the Graph and EWS (if you don't use MIME). It also opens up using SMIME for encryption and a more easy migration path for sending using SMTP in some apps. MimeKit is a great open source library for parsing and creating MIME messages so it offers a really easy solution for tackling this issue. The current documentation on Send message via MIME lacks any real sample so I've put together a quick console app that use MSAL, MIME kit and the Graph SDK to send a Message via MIME. As the current Graph SDK also doesn't support sending via MIME either there is a workaround for this in the future my guess is this will be supported.
