Hi All, We have ISA in integrated mode and have unique problem. One of our users wanted to check the mails from his server using browser. he can access the website but when he clicks the mail link the site is redirecting to another https page which is on port 5050. I have opened the TCP port 5050(inbound and outbound) but page does not show up. It shows the blank page. Pls. let me know if i need to do any other configuration. The link is something like this: https://mailserver.xxx.org:5050/exchange/ <https://mailserver.xxx.org:5050/exchange/> Pls let me know. Regards, Vinay.
