Powershell – Get todays appointments from outlook with powershell: Unwanted results


I'm extracting todays appointments with the following code:

$olFolderCalendar = 9
$ol = New-Object -ComObject Outlook.Application
$ns = $ol.GetNamespace('MAPI')
$Start = (Get-Date).AddDays(-1).ToShortDateString() + " 00:00"
$End = (Get-Date).AddDays(+1).ToShortDateString() + " 00:00"

$Filter = "[MessageClass]='IPM.Appointment' AND [Start] > '$Start' AND [End] < '$End'"

$Appointments = $ns.GetDefaultFolder($olFolderCalendar).Items
$Appointments.IncludeRecurrences = $false

foreach ($Appointment in $Appointments.Restrict($Filter) ) {

All todays appointments are listed but also a lot of recurring appointments that are NOT taking place today (birthdays, weekly appointments, …). Any idea how to avoid that?

EDIT: Seems like all this unwanted appointments are originally from my mobile synced to outlook. I'll try the script on a 'clean' PC.

EDIT: I tried the script on another PC without synced elements and it's the same: All recurring elements are display whether they are today or not.
AND [IsRecurring] = '$False'
is not helping either.

Best Solution

The initial query must include the original appointment of the series, so if the series started 3 months ago, the collection of appointments ($folder.items) date range must be set accordingly.

Afterwards you can filter for the desired date range.

This code works:

Function Get-OutlookCalendar
 echo starting...
 Add-type -assembly "Microsoft.Office.Interop.Outlook" | out-null
 $olFolders = "Microsoft.Office.Interop.Outlook.OlDefaultFolders" -as [type]
 $outlook = new-object -comobject outlook.application
 $namespace = $outlook.GetNameSpace("MAPI")
 $folder = $namespace.getDefaultFolder($olFolders::olFolderCalendar)

 $a = Get-Date -Hour 0 -Minute 00 -Second 00
 $b = (Get-Date -Hour 0 -Minute 00 -Second 00).AddDays(7)
 echo From $a To $b

 $Appointments = $folder.Items
 $Appointments.IncludeRecurrences = $true

 $Appointments | Where-object { $_.start -gt $a -AND $_.start -lt $b } | Select-Object -Property IsRecurring, RecurrenceState, Subject, Start, Location

} #end function Get-OutlookCalendar

To run this -for dummies, like myself yesterday :)
