outlook anywhere configuration

hi,

I have a new EV 10 environment.

internal and owa connection is ok ,works.

but in https outlook anywhere connection archived mails are couldnt open. (items are using port 443 with ssl seltificate)

As you know if customer has isa,tmg,juniper,asa....then we can create a rule for;

all of the internal request translate to the external one:

for ex: archive.company.local-->archive.company.com 

customer has no product for outside connection they are just using firewall,they say that we couldnt done link translation on firewall .

when i collect client trace items try to open from archive.company.intra but in external environment it is normal they couldnt open ,so i need to translate this link to archive.company.com for reach ev server.

what is your idea?

what will be the configuration steps without isa,juniper,asa or any other product?

are there any way to configure anywhere without link translation?

thanks...
