Hi , Thanks for the responce!! User gets the login page, after typing in user name and password this error message is displayed. On more important observation is that, if administrator logs in to OWA and then type the mailbox name of the user who is having problem, it goes through fine. Example: I login in as administrator to OWA. This is administrator mailbox. Now I just change the url to https://mailserver/exchange/username now it works. This clearly shows there is permission issue for that particular user. But permissions seem to be OK on the mailbox. As I mentioned earlier also if directly connect to backend server then it works fine even with the mailbox owner user name and password. For example: https://backendserver/exchange the user is prompted for user name and password, then it logs in without any issue. NOTE: I am using FBA on FE and normal authentication on BE.

Have you tried from other machines and OS's? If you're doing https redirection, try specifying the https so it doesn't have to redirect. Also go into IE and toggle the "show friendly http error" messages in the tools internet options, advanced menu. --------------------------------- From: Bruce J.

There is a FE / BE server. One user is getting the below error when logged through FE. But from BE it works fine. You are not authorized to view this page HTTP Error 403 - Forbidden Internet Explorer Checked permission it seems to be OK. Another user had faced this problem, then i had deleted the mailbox and re-created which solved the problem. But for this case i dont want to do the same thing. Need your help on this.
