php-ews访问所有日历，包括共享

Question

I have a calendar for a conference room shared with me. What I am hoping to do is to use php-ews to pull that calendar schedule for display. So far, I have been able to easily display my OWN calendar without issue. This was done using the code at: https://github.com/jamesiarmes/php-ews/wiki/Calendar:-Get-List-(Retrieving-Id-and-ChangeKey)

I saw on a similar question ( php-ews: Access shared calendars? ) someone suggesting adding these lines in the "Only look in the calendars folder" section:

$request->ParentFolderIds->DistinguishedFolderId->Mailbox = new StdClass;
$request->ParentFolderIds->DistinguishedFolderId->Mailbox->EmailAddress = 'email@address.com';    

This didn't break the code or anything, but it also didn't change the results. I was still only given my own calendar as a result. I have seen mention of impersonation as one method, but since the calendar is shared with me already I don't think that should be necessary. Is there something I have overlooked? I do have the identity path of the calendar, which is (replacing identifying details with words in CAPS): DOMAIN.com/OU/USERNAME:\\calendar\\NAME OF CALENDAR

I hope this is enough to help solve the problem. There are a couple questions on stack overflow dealing with this (but without answers that solved my issue), so if we get it sorted I will be sure to pass on the solution to those locations as well.

Answer 1

The value of 'email@address.com' needs to be the primary SMTP address of the conference room. If you're already doing that, it would be helpful to see the full SOAP request that gets sent to the server.
