Hi, long time roamer, first time poster.

I work help desk for a company and am having a problem with one particular user account. When using OWA, opening any email attachment will lock out the account. The attachment will open, but account locks out every time. If the user opens an attachment in a regular desktop Outlook client, the account doesn't lock out. Any idea what makes the account lock out only in OWA? No other users have this problem.
