EWS PowerShell view Autocomplete cache

Question

I'm trying to view the Outlook autocomplete cache via an EWS PowerShell script. The data is stored under Inbox (associated contents folder) > ipm.configuration.autocomplete > PR_ROAMING_BINARYSTREAM. I can access it using MCFmapi but don't know how to call an associated contents folder using EWS?

Answer 1

Associated contents can be accessed just like regular visible items - just specify Traversal="Associated" -  https://docs.microsoft.com/en-us/previous-versions/office/developer/exchange-server-2010/dd633693(v%3Dexchg.80)

You can play with that in OutlookSpy  - click GetFolder on the Outlook Spy ribbon (EWS group), go to the "Items (FindItem)" tab, change FindItem.Traversal combo box, click "Call FindItem".

Answer 2

Thanks, I was able to do just that using this script - https://github.com/gscales/Powershell-Scripts/blob/master/EWS-FAI/Module/functions/FAI/List-FAIItems.ps1 .

But I still don't know how to get the text from the property PR_ROAMING_BINARYSTREAM . I need to script this so I can't really use OutlookSpy.

Answer 3

You can either use GetItem or specify that binary property in ItemShape.AdditionalProperties

Answer 4

Oh, and OutlookSpy is for figuring things out, not for using in your code.

Thanks, will give it a try.

Answer 6

I tried loading the BinaryStream but I get nothing back:

	$ps = new-object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties) 

	$PR_ROAMING_BINARYSTREAM = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition(0x0102, [Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Binary)
	$ps.Add($PR_ROAMING_BINARYSTREAM)   

        if ($fiItems.Items.Count -gt 0)
	{
		foreach($Item in $fiItems)
		{
                	if($Item.ItemClass -match "IPM.Configuration")
			{
				$ItemClass = $Item.ItemClass
				$Subject = $Item.Subject
			
				if ($subject -eq "IPM.Configuration.Autocomplete")
				{
					$item.load($ps)
					Write-host "$itemclass"

					$list = $null  
					[void]$item.TryGetProperty($PR_ROAMING_BINARYSTREAM, [ref]$list)

					write-host "$list" 

				}
			}
		}
	}

It finds IPM.Configuration.Autocomplete but can't seem to load the binarystream. I looked at ItemShape.AdditionalProperties but couldn't find any working examples for PowerShell.

Answer 7

0x0102 is PT_BINARY. You want 0x7C09.
