It's expecting a string argument. Without explicitly making it a string, the parser is getting confused by that colon.
In powershell you can have something called psdrives, which map and act like dos drives, but can have arbitrary names (not just a single letter). That colon is making it think it's looking for a folder called \calendar at whatever psdrive is named $_. There's no such drive, so the result is null. Those extra bits make it parse as a literal string instead of a psdrive and path.

I'm curious though as to why the extra parts are necessary though. ________________________________ From: Campbell, Rob [rob_campb...@centraltechnology.net] Sent: Thursday, January 12, 2012 1:09 PM To: MS-Exchange Admin Issues Subject: RE: Script assist Does this work any better? Get-content list.txt | foreach-object -process {add-mailboxfolderpermission "$($_):\calendar" -user "Admin Assistants" -accessrights Editor} From: Damien Solodow [mailto:damien.solo...@harrison.edu]<mailto:[mailto:damien.solo...@harrison.edu]> Sent: Thursday, January 12, 2012 10:26 AM To: MS-Exchange Admin Issues Subject: Script assist Ok, this should be easy but I'm missing something dumb. I have a list of email addresses for mailboxes and I want to grant a group Editor rights to the calendar of every mailbox in that list. Here's what I'm running: Get-content list.txt | foreach-object -process {add-mailboxfolderpermission $_:\calendar -user "Admin Assistants" -accessrights Editor} When I run it I get "the specified mailbox "\calendar" doesn't exist. If I do get-content list.txt | foreach-object -process {write-host $_} I get a list of the email addresses in the file. Get-content list.txt | gm says they are strings. Exchange 2010 SP2.
