I'm trying to activate Out of Office for a mailbox on exchange 2007 through powershell.
I'm using the EWSOofUtil.dll from http://telnetport25.wordpress.com/2008/03/16/quick-ish-tip-exchange-2007-setting-oof-for-users-via-powershell-2/
And I can't get it working unless I provide the mailbox owners credentials.
But I don't know all passwords of all users.
If i run it as ExOrgAdmin I get an 'unauthorized', and if I run it as ExViewOnlyAdmin I get 'User is not not mailbox owner'
Is there another way to do it?
I dont' want to do it through CDO, although with CDO it works fine.
