Microsoft Teams Call History Outlook/OWA Addin

One of the Microsoft Teams features that I like the least is call history, for a number of reasons firstly its quite limited only 30 days worth of data and only includes direct calls and not meetings (which are often just scheduled calls). So when it comes to actually answering a question (like the one I found myself asking last week) when did I last have a call or meeting with person X it can't be used to answer this question.  The other thing is having that information available in the context of Outlook/OWA is a lot more useful for me (anyway) then digging through anther client to find its doesn't answer the question anyway. However while the call history in Teams only goes back 30 days the Teams CDR (Call Data Records) which I covered in https://dev.to/gscales/accessing-microsoft-teams-summary-records-cdr-s-for-calls-and-meetings-using-exchange-web-services-3581 do go back as far as your mailbox folder retention period. So with a little work I can use Exchange Web Services to create an Outlook/OWA addin that can be used to show the Call history for a person inline in OWA when you active it on a message you received from that user Eg


How this works is that the CDR item that is stored in the Mailbox stores the participants of the Call or Meeting in the recipients collection of the CDR mailbox item. The means you can make a KQL query on the participants to find all the CDR items that involve a particular user based on the sender address of the Email that the OWA Addin is activated on. eg the EWS Query ends up looking like


The extended properties that are used for the Start and End are pidTagStart and pidTagEnd which get set on the CDR mailbox item and then the SenderEmailSMTP address is used to work out who is the Organizer or the call initiator. To work out the type of Call the ItemClass is used so the last part of the ItemClass will tell you what the CRD is for eg call or meeting (If your wondering if you could do the same with the Microsoft Graph the answer is no because the Items in question are not a subclass of IPM.Note so aren't accessible when using the Microsoft Graph)

I've posted the code for the Addin in the following GitHub repository https://github.com/gscales/Microsoft-Teams-Call-History-Outlook-OWA-Addin

Want to give it a try yourself ?

I've hosted the files on my GitHub pages so its easy to test (if you like it clone it and host it somewhere else). But all you need to do is add it as a custom addin (if you allowed to) using the

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
