I've not seen this error before, but do you really have that left-hand single quote character in your filter? "((RecipientType -eq 'UserMailbox') -and ((Title -like `Flight Ops Pilots')))" Your error mentions position 55, and that's where the ` is. There's also one here: + $scriptCmd = { & <<<< $script:InvokeCommand ` And I just don't think they're allowed. Unless that's just a typo in your post, and your actual command has the normal single quote?Mobile OWA For Smartphone www.leederbyshire.com email a@t leederbyshire d.0.t c.0.m
