There is an error in your Outlook Web Access configuration.
The authentication type specified on the OWA virtual directory is set to Anonymous. This check box must be cleared for Outlook Web Access to function properly.

Exchange 2007: The sequence of predicates is invalid

Summary: When creating a transport rule I got the following error: "The sequence of predicates is invalid" In this case it appears that the order or predicate rules mattered.

In this example, I was creating a rule to silently drop all messsages coming in from an external address to an internal address.

$Condition = Get-TransportRulePredicate FromAddressContains
$Condition1 = Get-TransportRulePredicate SentTo
$Condition.words = @("externaluser1@gmail.com","externaluser2@gmail.com")
$Condition1.addresses = @(get-mailbox user1)
$Action = Get-TransportRuleAction DeleteMessage
New-TransportRule -Name "Deny Senders to Cellulardeals" -Condition @($Condition,$condition1) -Actions @($Action)

This would yield "The sequence of predicates is invalid" However after swapping the condition to put SentTo before FromAddressContains it works fine.

$Condition = Get-TransportRulePredicate SentTo
$Condition.addresses = @(get-mailbox user1)
$Condition1 = Get-TransportRulePredicate FromAddressContains
$Condition1.words = @("externaluser1@gmail.com","externaluser2@gmail.com")
$Action = Get-TransportRuleAction DeleteMessage
New-TransportRule -Name "Deny Senders to Cellulardeals" -Condition @($Condition,$condition1) -Actions @($Action)
