Creating Summary Emails for Inbox, Sub or Public Folders

This is one script that has a number of different uses the basic premise of this script is that it will produce a summary email of all the email that exists in a folder for a certain time period. For example if you have a public folder where mail may be arriving in and you want people to receive a summary once a day of all the email that was received in this folder for the past 24 hours or . I also use this for different listservs I subscribe to where I have some rules moving email from different lists to a certain folders than I run the script to summarize mail that was received in that folder over the last 24 hours . The summary includes who the message was from what time it was received and also an Oulook link so if you do want to view the mail you can click on the link and it will take me to the appropriate message in Outlook.

The script works by querying a folder using exoledb for messages that arrived after a certain date. Because Exchange stores the received time in UTC there’s some code to first convert the query time to UTC and then also format the date/time into ISO format that is required by Exoledb. The code builds a HMTL table that is going to be used as the body of the message to provide the outlook links PR_EntryID is included in the Exoledb query and a function is used to convert this into a Hex String. The Hex String can then be used in a hyperlink in the Outlook:entryID format. The last part of the code is responsible for sending the message. The send is done using CDOEX sending via SMTP port 25 on the server.

To use this script the following lines need to be customised.

Mailboxurl = http://mailbox/exchange/mailbox/inbox

Use your own mailbox or public folder URL (just cut and past the OWA URL)

dtListFrom = DateAdd("d",-1,dtListFrom)

This controls the time period for the query the default is 1 day (24 hours)

objEmail.From = "source@yourdomai.com"
objEmail.To = target@yourdomain.com

Set this to valid source and target email address's

objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "servername"

Set this to a valid servername of the Exchange server you running it on.

Because the code uses Exoledb it must be run locally on an Exchange server with an account that has rights to the mailbox or public folder you’re querying. If you want to run it regularly then a scheduled task can be used locally on the server.
I’ve put a downloadable copy of the script here the code itself looks like

Mailboxurl = "http://server/exchange/mailbox/inbox"

Emailreport = "<table border=""1"" cellpadding=""0"" cellspacing=""0""

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

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

Testing and Sending email via SMTP using Opportunistic TLS and oAuth in Office365 with PowerShell

As well as EWS and Remote PowerShell (RPS) other mail protocols POP3, IMAP and SMTP have had OAuth authentication enabled in Exchange Online (Official announcement here ). A while ago I created  this script that used Opportunistic TLS to perform a Telnet style test against a SMTP server using SMTP AUTH. Now that oAuth authentication has been enabled in office365 I've updated this script to be able to use oAuth instead of SMTP Auth to test against Office365. I've also included a function to actually send a Message. Token Acquisition  To Send a Mail using oAuth you first need to get an Access token from Azure AD there are plenty of ways of doing this in PowerShell. You could use a library like MSAL or ADAL (just google your favoured method) or use a library less approach which I've included with this script . Whatever way you do this you need to make sure that your application registration  https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-
