Microsoft Exchange Server remote access

[tmpadmin]

I have setup our exchange server and all is running perfectly fine. I can access e-mail from anywhere. Unfortunately, my boss want to have some way to be sure that not everyone in the company can access their mail from home. Only those who are "authorized" should have access. Aside from hiding the setup instructions, is there a setting in Exchange 5.5 that will allow this? I already know I can turn off access through POP3 and IMAP but is there a way to stop external access through exchange settings? Essentially I setup each external computer with the hosts files and away they go. This is somewhat secure and to be honest enough to keep anyone in my company out but I know my boss will want more. Any help would be great, even "Exchange 2K does that".

Thank!

Dear fellow, what OS are you using, if NT, you can set up the USER ADMIN FOR DOMAINS to allow only those that you give permisions to to access the mailserver etc, times allowed etc. Access times and users can also be controlled through exchange server with their personal profiles generated at the time of user setup, don't allow remote access (remote dial in) is part of the user setup, there's many ways to control\restrict\stop\deny users from accessing email. I always harp on the resource kits available for the OS and apps you use from , yes, I hate to say, MICROSOFT.

I see what you are saying and I have a good grasp on NT security, however here is my dilema. I need everyone in the company to be able to get their e-mail in the office at all times and only a select few to get their e-mail from home and the office all the time. I need to be able to have this availability for everyone when it is deemed necessary for them to have it. My company feels it is not necessary to have everyone accessing e-mail from home so they feel it is necessary to block out everyone (from home) unless approved. So, time, server, etc. restrictions will not work in this case.

thanks again for the help.
