Hello  ,

 

Thank you for the reply, maybe I haven't cleared exactly what I'm looking to achieve. It is not related to DNS or FQDNs. It is related to logging in to the OWA. So, if a user types <Username>@domain1.com, he can access .. But if he types <Username>@domain2.com, ASM should block such traffic ..

 

I mean, I want only <Username>@domain1.com to be working, but any other domain to be dropped showing ASM block page.

 

Hope this clears what I'm looking to achieve.

Hello,

 

Do you have any login page in your ASM configuration?

If you deal with logging, then better to configure appropriate login page.

 

Thanks, Ivan
