Because the firewall had to process several inbound packets, legitimate users complained about OWA's extremely slow performance.

The organization had an advanced firewall or intrusion detection software (IDS) that prevented most attacks, but the firewall could only process a certain number of packets per second. For instance, one organization I worked with was constantly being attacked by hackers. Therefore, unless you have sufficient bandwidth to support all of your mobile users - and anything else that you might be using the connection for - your clients will experience slow performance.įirewalls can contribute to performance problems. All mobile users are competing for Internet bandwidth when accessing the OWA server. In real-life situations, these two components can be major contributors to OWA performance problems. Although OWA can become overloaded, another common source may be an underlying component.Ĭheck your Internet connection and your firewall.

If you want to improve OWA's performance, you first must determine whether or not it's the root cause. Is OWA really causing your performance problems?
