Powershell: export multiple users calendars and deltas


So my company is migrating to Office 365 from exchange server (2008 and 2010). I was given the task of exporting everyone's email to a pst file using a powershell script which I successfully completed, but now I have to do the same for their personal calendars as well as the "deltas". I'd like to know if this is possible using powershell as well.

You should be able to export calendar items with New-MailboxExportRequest using the "IncludeFolders" parameter.

New-MailboxExportRequest -Mailbox "MAILBOXUSER" -IncludeFolders "#Calendar#" -FilePath "\\FILEPATH\EXPORT.PST"

What about multiple users in Active directory? And only those with a email?
Todd NelsonSystems EngineerCommented:
What about them?  The command is only for use with mailboxes.  Because of the nature of exports, the command must be run for each mailbox you choose to export data from.  Like this...

$mbx1 = Get-Mailbox -ResultSize Unlimited
foreach ($user in $mbx1) { New-MailboxExportRequest -Mailbox $user -IncludeFolders "#Calendar#" -FilePath \\FILEPATH\$user.PST }

Open in new window

If you need to export based on a specific date, you will need to use the "ContentFilter" parameter.  Like this...

$mbx1 = Get-Mailbox -ResultSize Unlimited
foreach ($user in $mbx1) { New-MailboxExportRequest -ContentFilter {(Received -lt '03/01/2018') -and (Received -gt '02/01/2018')} -Mailbox $user -IncludeFolders "#Calendar#" -FilePath \\FILEPATH\$user.PST }
