Conversation statistics with EWS

Conversations have been a hot area in the Messaging space recently with many different solutions jockeying for attention such as Yammer, Office365 Groups , Slack, HipChat, Skype for business and many other. Each solution offers a different method to communicate and thread different conversations in different ways  over different clients and communication platforms. Typically in Exchange conversations either take place in Mailboxes or Public folders while Groups are a now a newer offering.

When it comes to reporting, looking at conversations can offer some interesting insights as to when conversations are happening how many people are participating and where a Group or Channel based solution might provide some form of productivity gain or usefulness.

In EWS in Exchange 2010 and greator the findconversation operation allows you to query and group conversation threads in a Mailbox folder and you can then use the information returned about the conversations to get the individual conversation items in a Mailbox using the Batch EWS operations. 

To demonstrate some of this I've come up with a PowerShell module that does just that it first uses the FindCoversation operation to get the Messages from the Inbox of a Mailbox or other folders if you use the FolderPath switch.  The script enumerates all the available message from the conversation that it looks at (eg those with more then 2 participants and 2 messages). It then compiles statistics for each conversation about the

Number of messages, participants
Start and duration of the conversation thread in hours
The original sender of the thread and how many messages they sent
The loud mouth (the person who isn't the originate of the thread  who has responded the most) and number of Messages. from this person

I've put a copy of the module on GitHub here https://github.com/gscales/Powershell-Scripts/blob/master/EWSConversation.ps1 to run the script you pass in the Mailbox you want it to run against and period of days to look back eg

 Get-ConversationStats -MailboxName gscales@datarumble.com -Period 60

If you are moving conversations into a different folder in a Mailbox using a Rule eg from a Distribution list you can report on these folders using the FolderPath parameter eg

 Get-ConversationStats -MailboxName gscales@datarumble.com -Period 60 -FolderPath \Inbox\BlahGroup

Downloading a shared file from Onedrive for business using Powershell

I thought I'd quickly share this script I came up with to download a file that was shared using One Drive for Business (which is SharePoint under the covers) with Powershell. The following script takes a OneDrive for business URL which would look like https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filename.txt This script is pretty simple it uses the SharePoint CSOM (Client side object Model) which it loads in the first line. It uses the URI object to separate the host and relative URL which the CSOM requires and also the SharePointOnlineCredentials object to handle the Office365 SharePoint online authentication. The following script is a function that take the OneDrive URL, Credentials for Office365 and path you want to download the file to and downloads the file. eg to run the script you would use something like ./spdownload.ps1 ' https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filena

A walk-though using the Graph API Mailbox reports in Powershell

Quite recently the Reporting side of the Graph API has moved in GA from beta, there are quite a number of reports that can be run across various Office365 surfaces but in this post I'm going to focus on the Mailbox related ones. Accessing Office365 Reports using Powershell is nothing new and has been available in the previous reporting endpoint  https://msdn.microsoft.com/en-us/library/office/jj984326.aspx however from the end of January many of these cmdlets are now being depreciated in favour of the Graph API  https://msdn.microsoft.com/en-us/library/office/dn387059.aspx . Prerequisites  In comparison to using the Remote PowerShell cmdlets where only the correct Office365 Admin permissions where needed, to use the new Graph API reports endpoint you need to use OAuth for authentication so this requires an Application Registration  https://developer.microsoft.com/en-us/graph/docs/concepts/auth_overview  that is then given the correct oAuth Grants to use the Reports EndPoin

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
