Windows XP SP2 includes a number of security enhancements that can affect OWA. The most noticeable issue is caused by the pop-up blocker preventing some of OWAs windows from opening. This problem isn’t new, it’s has been a long standing problem with nearly every pop-up blocker available, but it’s going to affect a lot more users now that Windows XP has a pop-up blocker enabled by default.
Steps required to insure OWA works correctly:
- Use the Information Bar setting to trust the OWA site all the time or temporarily.
- Add the OWA site to the Trusted zone in Internet Options to insure JavaScript and Active X (used for S/MIME control) work correctly.
