Exchange proxyaddress display and removal powershell gui for Exchange 2003,2007,2010

ProxyAddresses are something in Exchange environments that can be a challenge to maintain over a long period of time and also during migrations or consolidations something that you need to deal with. If your lucky then just modifying your recipient policies may work the magic that you need if not and you have a large number of users that you need to modify you need to look at creating a script or doing a lot of mouse work.

The first challenge if your going to write a script to do this is because your going to be deleting information just doing a one-liner or simple script may mean you will end up removing more information than you want. So one way to tackle this is using a simple GUI script that will allow mutiple selects to at least control what and which accounts you are going to affect. The good thing about createing a simple Gui is that it can also be used to do some analysis first. So the script i've created allows you to search based on the proxy address domain you want to look at and also limit what branch of your domain you want to query eg the whole domain, OU or subtree OU query. It also has the ability to export the search results.

A few other things about this script is that it uses ADSI so should work against any version of Exchange. It uses Putex so it should only affect one entry in the proxyaddresses array (hopefully the one your targeting to delete) which is hopefully a little safer then some approachs simular scrisst take of rewriting the whole proxyaddresses object which if it goes wrong can get ugly.

The ldap query the script uses does a wildcard smtp* + the domain you want to search so it will match a full or partial match. There is also some code to stop you deleting any proxyaddresses that may be the primary email address which should be avoided.

To use the script you need to put the domain you want to search for in the format @proxyaddress.com and then click search. This should find any accounts with that paricular proxy addresses. To delete specific proxy address you need to select the row fully and click the delete button. The script is latched by default so will prompt on every deletetion there is a checkbox to disable this (but do so with great care).

Note this script if for demostration purposes only and has had no real testing so is only sutible for test enviroments. I've put a download of the script here

The script 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...

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.
