  • Exchange 2003 - OWA

    I have been searching for a definite yes or no for the following question. Can you restrict users logging into OWA via IP Address? I will give an example just to make myself clear, there are 2 users, “User A” and “User B”. User A works in an office in the USA, User B works in an office in the UK. User A can go to OWA and now type in User B’s credentials and he has access to his mailbox. Can I restrict it so “User B’s” emails can only be accessed on OWA on a specific IP address so if “User A” did gain his account info it would still block access?

    You can't restrict access down to IP address and user level.

    With Exchange OWA access is either on or off on a per user basis.
    With IIS, you can only restrict access to the entire site on an IP address/range basis.

    An ISA server protecting the Exchange server might be able to do it.

    Unfortunately you are trying to seek a technical solution to a behavioural problem.

      Agreed. There is nothing that user 1 has access to that user 2 can't be granted access to without logging on as user 1. Therefore there is no reason for any user to be sharing their password. You should force users to change their passwords if you suspect that they have done so, and enforce a strong IT policy.

        I am already aware of the above, we already have a strong IT policy. If users are found to have given their details out they will receive a disciplinary, we enforce regular password changes, we know how to grant permissions etc . The question was given to us by another department asking if it was possible. I do appreciate the swift responses though, thank you for your help!
