ECP still accessible if URL Rewriter is in use

Hi guys,

I've implemented few URL Rewrite rules within IIS, like "Force HTTP to HTTPS", "auto redirect to /owa", etc. All good with it, but now I can't disable ECP (Exchange Admin Center) for access from inside\outside. I mean, that Exchange Admin Center page is accessible, but provides access to personal settings (Outlook Web App: account, organize email, groups, etc.), instead of404 – website not found error or real admin center. To do it, I have to disable all URL Rewrite rules.

In my case internal and external URLs are the same.

Does anybody saw and solved that issue? Or maybe you can advise how to disable Admin Center only from internet access?

Thanks,

Nick
