Issues executing powershell commands in C#
I am trying to get our self-service email forwarding process to work in Exchange 2010 (we upgraded from 2003 where everything could be done right in Active Directory using the LDAP API). For 2010 it requires 3 steps. I am using System.Management.Automation which allows me access to the PowerShell class. The first to do is to create the forward contact which I do with a "New-MailContact" powershell command, and that works fine. Next, I want to hide the contact from the GAL which I do with a "Set-MailContact" powershell command. This command merely sets an attribute in the new contact object.
Finally (and this is where my problem is) I need to set the altRecipient attribute in the user object which I do with a "Set-Mailbox" powershell command. It works maybe half the time. The other half I get the following error:
Couldn't find object "catnet.wfo.linfield.edu/People/Contacts/Rob Tanner". Please make sure that it was spelled correctly or specify a different object.
The object does exist and the previous powershell command, to hide it from the GAL, would fail if it didn't. Any idea as to what's going on?
