As the title said, i have 2 mailbox servers (ex2k16) with :
1> abc.com (main domain of organization, active directory)
2> xzy.com (accepted domain) - i'd also made secondary owa website and it's working fine.
Recent days, i deploy an Office Online Server system with 2 servers (F5 load balancer). It's working fine for abc.com (preview and editing). But it's not working when i browse by xzy.com domain.
when i use an email : test1@abc.com, test2@xyz.com => i browse on https://mail.abc.com/owa, open office files => working
when i use an email : test1@abc.com, test2@xyz.com => i browse on https://mail.xyz.com/owa, open office files => not working, show error as attachment.
So please help ! did i miss something ?
