Let's say I want to get/set permissions of a folder called "Done?" under Inbox.

Get-MailboxFolderPermission "user:\Inbox\Done?"

returns:

The operation couldn't be performed because 'user:\Inbox\Done?' couldn't be found.
    + CategoryInfo          : NotSpecified: (:) [Get-MailboxFolderPermission], ManagementObjectNotFoundException
    + FullyQualifiedErrorId : 5E04CCC9,Microsoft.Exchange.Management.StoreTasks.GetMailboxFolderPermission

tried ` as an escape character but didn't work either. This is on PS v2, Exchange 2010

Any help will be appriciated!

Don't use illegal characters in folder names.

I just test this and it works fine:

[PS] C:\scripts> Get-MailboxFolderPermission 'testuser:\inbox\test?'

RunspaceId   : 9e2c16c7-4002-4f89-81da-2c8c55c7ed93
FolderName   : Test?
User         : Default
AccessRights : {None}
Identity     : Default
IsValid      : True

RunspaceId   : 9e2c16c7-4002-4f89-81da-2c8c55c7ed93

I think it is not a question mark after all. The Outlook folders contain forward slashes which are displayed as question marks. So when you pass that string to a set command, it throws an error because it can't find the path (because / becomes ?).

So Exchange cmdlets translate "/" in Outlook folder names to [char]63743, which in turn shows up as "?" in the cmdlet output. So before I pass the folder paths to add-mailboxfolderpermission in my script, I now do the following:

$Folder = $Folder.FolderPath.Replace("/","\")
$Folder = $Folder.Replace([char]63743,"/")

and it works now. Credit goes to BradS in the comments section of this blog

So I don't think there's anything wrong with my language set

I still haven't found a way to pass a folder path that contains "\" in the actual name of a folder (to set/add permissions to). Hopefully there aren't too many users that name their folders with "\" in them but Outlook doesn't stop you from doing so.

PS. Forgot to mention that these "?" symbols were coming up in the output of Get-MailboxFolderStatistics

Unfortunately that has nothing to do with what you asked.  The slashes referenced are not a question mark.  The question mark is not an issue as I have posted above.  If your language or locale are set wrong for Exchange 2010 or if you are not patched you may have issues with that.  If you run PowerShell v3 or later on Exchange it can give unexpected results pre-SP2.

Posting in the Exchange forum may help you sort this out.
