I may be wrong here, but as far as affecting clients accessing the webmail from another organization, it shouldn't matter since clients normally use a random port number >1024 to access servers. But I'm still pretty new to some of this stuff, so someone please correct me if I'm mistaken.

I am going back and forth on this one with a consultant on this one and need an expert opinion. So, I turn to you :) When configuring webemail (such as owa) that is using https, is it better to change the default port (443) to an uncommon port (20000)for security reasons? Does it secure it further by doing this? Wouldn't it cause more issues than anything if you try to access that site from inside an org that only allows port 80/443 and 21 out? Thank you in advance for any opinions you may share.
