PowerShell Exchange disable OWA from OU sort

Question

I am searching a specific OU, then disabling OWA for all users in the OU. This script runs daily.

I have the following script that works properly but is updating ALL the users in the OU.

$OU='OU=SomeOU,DC=Domain,DC=com'
$ext14='00254'
Get-Mailbox -OrganizationalUnit $OU| Where {$_.CustomAttribute14 -eq $ext14} | Set-CASMailbox -OWAEnabled:$false

I would like to ONLY update users that -OWAEnabled is set to $True (and change to $false) in this OU and sub OUs. This would reduce my calls to Exchange. Unfortunately, Set-CASMailbox does not seem to have an OU or CustomAttribute property to query against.

Any suggestions??

Try this:

Get-CASMailbox -OrganizationalUnit $OU | ? {
  $_.CustomAttribute14 -eq $ext14 -and $_.OWAEnabled
} | % {
  Set-CASMailbox -Identity $_.Identity -OWAEnabled:$false
}

The CASMailbox object does not have the OU or CustomAttribute properties, but the Mailbox object does have protocolsettings property collection, so:

$OU='OU=SomeOU,DC=Domain,DC=com'
$ext14='00254'
Get-Mailbox -OrganizationalUnit $OU|
Where {($_.CustomAttribute14 -eq $ext14) -and ($_.protocolsettings -match 'OWA.1'} |
Set-CASMailbox -OWAEnabled:$false

i wonder if there is a similar one for -MAPIBlockOutlookRpcHttp? – GreetRufus Mar 26 '13 at 15:31
Yes, found it. MAPI.0 Excellent!! – GreetRufus Mar 26 '13 at 15:39
Probably. I don't know where you'd find the docs on how that's stored in those protocolsetting strings, but I'd wager with a little experimenting you could figure it out and write the regex you need to match it. – mjolinor Mar 26 '13 at 15:42
