Script to assign mailbox folder permissions for users

Question

How would a script be written that accomplishes the following task? In this scenario, UserA would be selected with the Modify user action, then UserB would be input to add required permissions. If it would be possible to select or search for "UserB" instead of inputting "UserB" that would be a more desireable solution.

Add-MailboxFolderPermission -Identity UserA:\Calendar -User UserB -AccessRights reviewer

I've already created a homepage action with a customized imput, although being able to browse to select the user object, or search for the user object would be nicer. Now I'm attempting to complete the business rule that runs the script to allow reviewer permissions on UserA's calendar for UserB

Hello Michael,

Judging by the screenshot that you sent us the script that you were testing for this task has a couple of issues.

First of all, in your script you call the $Context.SetModifiedPropertyValue method with only one argument, which is incorrect. The method should be called with two arguments: $Context.SetModifiedPropertyValue("<property_name>", <new_property_value>). Also, there is another error when an Exchange management cmdlet fails due to a missing parameter.

I suspect that you just confused the $Context.SetModifiedPropertyValue and the $Context.GetModifiedPropertyValue methods in your script. Can you post the full text of your script here so we can resolve the issue?

I'm sure there are things missing or incorrect from my script. Scripting isn't one of my stronger skillsets

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010
$username = "%username%"
$Context.GetModifiedPropertyValue("CustomAttributeText1")
Add-MailboxFolderPermission -Identity %username%:\Calendar -User %CustomAttributeText1% -AccessRights reviewer
$Context.SetModifiedPropertyValue("CustomAttributeText1",$NULL)

Michael,

Here's the modified script. Now it should work:

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010
$identity = "%username%\Calendar"
$calendarReviewerUserName = $Context.GetModifiedPropertyValue("adm-customAttributeText1")
Add-MailboxFolderPermission -Identity $identity -User $calendarReviewerUserName -AccessRights reviewer
$Context.SetModifiedPropertyValue("adm-customAttributeText1",$NULL)

Thanks very much! Worked like a charm!
