Dear Support, i have a client with SBS standard 2003 installed, they use OWA to check their emails, many users use the same account in OWA. before removing ISA from the SBS, clients use to receive a popup screen when logging to OWA to insert their username and password, the page remains opened till the end of the day after removing ISA, clients receive a page (not a popup screen) when logging to OWA page to insert their username and password. the problem now is that the page expires every few hours and they to reinsert their username and passwords. Again; many users use the same account in OWA. we tried choosing private instead of public while using OWA but same result how can i solve this? how can i stop the page from being expired ? and stil keep many users logging with the same shared account thanks Haitham
