Looking for Script Exchange-2007: Import-Mailbox Calendar Folder on multiple mailboxes {Distribution Group}

Question

Hi,
I'm looking for a PowerShell script which will import a Calendar events into student's mailbox (Calendar). Those students are located in a distribution group and I would like to target the distribution group; I'm trying to simulate what I want to achieve
in the below code example, I would appreciate if anyone jump in and advise.
$Users = Import-Csv C:\users.csv | ForEach-Object{Get-DistributionGroup -Identity SC-1213} | Import-Mailbox -Identity $Users -PSTFolderPath c:\Calendar.pst -IncludeFolders '\Calendar' -StartDate -EndDate
Much appreciated..

The logic doesn't work unless you are using StartDate and EndDate for the period when you change the item.  As I said above, StartDate and EndDate are not the times when the meeting starts and ends - they are the times that the item was either added
or modified in the mailbox.  Your filter was trying to pull items that were in the future.
And as I also said above, if you import a modified item, the original is
not going to be updated.  You will have a duplicate meeting
on the calendar.  You would have to remove the original
and import the updated item if this was how you wished to manage the updates.  This is not nearly as effective as
sending meeting requests and updating those meetings.
For example, if we do things the way you are doing them, and we add a "Student Appreciation Bonfire" meeting to the calendar for April 12 at "The Quad", we would do the following:
On February 1, you get information for the meeting that needs to be imported
You create this new meeting in the PST calendar - "Student Appreciation Bonfire"; Date April 12, start 8:00 AM, end 12:00 noon; Location The Quad
You import the PST into everyone's calendar
You receive a note on March 12 saying the venue has changed to The River Beach, so you update this meeting in your PST
Since there are other calendar items in the PST, you import the update using StartDate of March 12 and EndDate of March 13 - the date that you changed the item, not the date the item occurs
At this point, all users have two meetings on their calendar - the original and the update
If, instead of doing it this way, you create a Student Actvities Calendar mailbox, you would handle it this way:
On February 1, you get information for the meeting that needs to be imported
You create this new meeting in the Corporate calendar - "Student Appreciation Bonfire"; Date April 12, start 8:00 AM, end 12:00 noon; Location The Quad
You invite everyone to the meeting
You receive a note on March 12 saying the venue has changed to The River Beach, so you update this meeting in that calendar and send out the update
At this point, all users have only the one meeting on their calendar - the update
Using the PST as the source for the meetings would work only for items that
will not be changed - holidays are a good example.
