Using EWS to work with mail items from a range derived from Get-Date RRS feed

  • Question

  • I am attempting to write a powershell script that uses EWS to move items from the prior month and create a folder named after that month to hold those items. 

    I am finding that the search filter only likes the format if you use .NET system.DateTime and not Get-Date.

    However it's strange, for testing I configured my variable to be the exact same format as the .NET format but it rejects it. 

    The error i receive is: 

    Exception calling "FindItems" with "2" argument(s): "The specified value is
    invalid for property."
    At line:1 char:1
    + $frFolderResult = $InboxFolder.FindItems($sfCollection,$view)
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
        + FullyQualifiedErrorId : ServiceResponseException

    For example, if i set $startdate and $enddate like this  $startdate=(([system.DateTime]::Today.AddDays(-60)))

    $startdate returns Monday, January 20, 2014 12:00:00 AM, and the search filter works fine.

    but if i set $startdate using this: $startdate = (Get-Date).AddMonths(-1).ToString("dddd, MMMM 01, 12:00:00 AM")

    It gets rejected event though the output is exactly the same.

    i.e. Friday, February 01, 2014 12:00:00 AM

    Any help would be appreciated. 

    Thank You.

  • The Managed API is expecting you to pass a Typed Value not a String so if you just use

    $startdatetime= [System.DateTime]::Parse("$startdate $searchyear 12:00:00 AM")

    That should work okay, the Managed API itself will then covert it to and from UTC and then submit the query eg

                <t:FieldURI FieldURI="item:DateTimeReceived" />
                  <t:Constant Value="2014-02-24T03:26:34.889Z" />

    Which you can see yourself if you enable tracing eg

    $service.TraceEnabled = $true

  • Thanks Glen.

    that didn't work exactly, it was throwing an error where it did not like the format of the day of week.

    However i tweaked that section of the code to the following format and now it works fine.

    $startdate = (Get-Date).AddMonths(-1).ToString("MM-01")
    $startdatetime= [System.DateTime]::Parse("$startdate-$searchyear 12:00:00 AM")
    $enddate = [System.DateTime]::DaysInMonth($(Get-date).Year, $(Get-date).Month -1)
    $priormonth = (Get-Date).AddMonths(-1).ToString("MM")
    $enddatetime = [System.DateTime]::Parse("$priormonth-$enddate-$searchyear 11:59:59 PM")
