Outlook folders

The functions we’ve seen so far have involved iterating through the whole set of Outlook folders. That’s a lot of folders (I have 4 email accounts with lost of folders). The trick is to do this just once and then use the GetFolderFromID method at the Outlook.Session level to access individual mailboxes

The problem is that this method uses the EntryID and the StoreID for the folder.  Examples are shown below

StoreID : 0000000038A1BB1005E5101AA1BB08002B2A56C200006D736E636F6E2E646C6C

EntryID : 000000000A9D24A8D4E32445825D043ADB203A6F0100D9539C2261A6BB45B9DA

Path    : \\\Deleted Items

Now I for one don’t want to be typing in the EntryID never mind the StoreID – chances of getting that right range from zero to about … zero

What we can do convert all of our Outlook functions (the two so far and the others I’ve got planned) into a module. In the psm1 file I can put a line that says

$folders = get-mailfolders

That creates a collection of objects containing the path, storeid and entryid for all of the folders. We can then search through that collection much faster than the outlook folders.

We create the collection like this

function get-mailfolders {            
$outlookfolders = @()            
$outlook = New-Object -ComObject Outlook.Application            
foreach ($folder in $outlook.Session.Folders){            
  foreach($mailfolder in $folder.Folders ) {            
   $olkf = New-Object PSObject -Property @{            
    Path = $($mailfolder.FullFolderPath)            
    EntryID = $($mailfolder.EntryID)            
    StoreID = $($mailfolder.StoreID)            
   $outlookfolders += $olkf            

Loop through the folders as we’ve already seen and create an object that has the path, storeid and entryid. Add the object to the collection and output the collection at the end of the function.

We’ll see how to use this collection in the revised clear-deletedmail function
