Good Day Friends,
I want to take calendar events with attendee list, by that I'm using CalendarDiagnosticObjects in PS, but in DisplayAttendeesAll part it's just showing the names. There are several people in the organization or in meeting request (as an attendee but out of organization) have the same name. How can I find all attendees email address, or cn number etc for internal ones.
Thank you.

Hi Guney,
First, I was wondering if you could share the specific cmdlets you used
Secondly, I did some checking and you can try to use “Get-CalendarDiagnosticObjects | Select-Object -ExpandProperty DisplayAttendeesAll Name, Address, CN” or “Get-CalendarDiagnosticObjects | Select-Object -ExpandProperty DisplayAttendeesAll | Select-Object Name, Address, CN” to get more Attendee information like email address etc.
For more information on Get-CalendarDiagnosticObjects see theGet-CalendarDiagnosticObjects (ExchangePowerShell) | Microsoft Learn
For Select-Object -ExpandProperty you can refer to theSelect-Object (Microsoft.PowerShell.Utility) - PowerShell | Microsoft Learn
Please check if this works
Hi Mike,
Thank you for your response, I'm also trying the similiar cmds on pwsh, but the issue is even for your cmd, it's returning the name not the email address or CN. The output of your cmd is Name and Surname for many of the attendees.
I guess the issue is, MS teams or maybe Calendar also, converting (even outside of the company attendees) email address to their name. And that Diognastic is not giving the email address. It's just showing the name, only for some, I can see the email and generally rarely contact outside of company domain users.
I couldn't find any other solution.
Thank you,

@Mike Hu-MSFT It's really too bad the Microsoft seems to have dropped the very helpful "Output" section of many cmdlets' documentation. The name of the output object and a link to the description of the output object in the help is, well, very helpful!
I haven't worked with Exchange for about ten years, but looking for information on the DisplayAttendeesAll, it seems to be a collection of objects. Only the names are displayed by the default view. Have you looked at the individual attendees in the "attendees" property of the calendar item? I think they are recipient objects. If they are they should have the LegagyExchangeDN, SMTP address, and RecipientTypeDetails.
All of that's unverifiable by me, though. I used to be an Exchange MVP for 16 years, though (before retiring), so it might be worthwhile taking a look.
If I'm wrong, try looking at the calendar item itself.
Hi Rich,
Thank you for your answer. I also thought it shows by default the name, but I couldn't find the address of the that names, or address of attendee in any other property under calendardiognastic objects.
Recipient objects, as I remember is giving the user info, I checked now also, and it doesn't show the name like shown in DisplayAttendeesAll. i.e, DisplayAttendeesAll shows Rich Matheisen, kobe.bryant@legend.etc, Micheal Jordan.
Where only Micheal Jordan is our domain user, or in the user list. So, Rich Matheisen has his own company email address but I couldn't find it where. So user, Recipient list will not give any detail for Rich Matheisen and kobe.bryant@legend.etc. Recipient object will show name in xxx.yyyy format, so I can't know micheal.jordan or micheal.jordan2 as name, of Micheal Jordan. Because there can be several people sharing the same name. But that part is not the main issue.
My main issue is to find a person email who s not in my domain, and shown in displayattendeesall area only with his name. in our example, Rich Matheisen.
Let me know if you have any cmd to try. Thank you for your time.
Are you using O365? You may have to use something like this (https://www.easy365manager.com/how-to-read-user-calendar-events-using-powershell-and-the-graph-api/#:~:text=To%20extract%20calendar%20information%2C%20use%20the%20Get-MgUserCalendarView%20CmdLet.,00%3A00%3A00%20PS%20C%3A%3E%20%24EndDate%20%3D%20Get-Date%20-Date%2023%3A59%3A59) to get the information from the calendar item.
I don't have access to O365 so I think my helpfulness is pretty much at an end.
