Exchange 2010 - Blocking OWA for CERTAIN users from the outside
Posted on 2012-08-17
Hello guys, we are an Exchange 2010 Shop with about 1200 mailboxes.
My question relates to our need to block OWA from the outside for a number of reasons and in certain scenarios. Here we go.
1. We have a need for a certain number of Generic accounts, and they need to use OWA from the inside since they do not have Office and the users float from PC to PC. Outside the company, I would like to BLOCK OWA since these are generic accounts and the passwords do not change. So I need to block JUST these users on the outside. These generics all begin with the same pattern b1***, B2***, etc if that helps.
2. The second issue is related to our normal users using a web scraping app on their mobile phones. There are apps that exist on iphone and android that allow you to have email on these devices (these apps screen scrape OWA) and make it look like a mail client for the phone. We want to block this, because the passwords get cached and no passcode lock is forced. All of our mobile users SHOULD connect through our MDM/ActiveSync solution (MobileIron). So for these OWA users that CAN get to OWA from the outside, I want to block these types of apps.
If i cannot get around these issues, I will have to shut OWA down for everyone from the outside.
Any help is appreciated.
