Reporting on Folder RetentionTag Statistics Exchange 2010-16

Mailbox retention tag application and management are one of the more complex administrative tasks on Exchange from 2010 and one task scripting can be a great help with.

With EWS there are two ways you can deal with retrieving the Retention Tags that have been applied to a Folder or Item. In 2013 and 2016,  EWS returns the retention tags applied to a folder or Item as a Strongly typed property which makes things easier to deal with. In Exchange 2010 you need to access the underlying extended properties for Retention tags (this will also work on 2013 and 2016 because the extended properties are the same).

I've posted up a script module on GitHub here https://github.com/gscales/Powershell-Scripts/blob/master/ReportTagged.ps1 that can do this using the Extended properties so it will work on Exchange 2010 and up.

Report-TaggedFolders  - Creates a Report of the FolderTag applied to each of the Folders in a Mailbox (if they are tagged). To get all the availbile Personal Tags the Exchange Management Shell Get-RetentionPolicyTag cmdlet is used. The script also then uses the Tag retrieved from the folder to report then number of Items in that folder that have that Tag applied and produces a report like


Report-UntaggedFolder - Creates a Report of the Untagged Folder in a Mailbox with the FolderClass, ItemCount and ItemSize.

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 ...
