Hi Team,
I'v got 2 Exchange 2013 CAS/Mailbox (same server virtualized) sitting on my head office. I need to look into providing external user access. Since there's no Edge in 2013, I would like to know what are the best practices and Microsofts recommended approach for this.
1. How to address Edge replacement
2. Do I need to have TMG or any proxy server for OWA publishing or can i directly do that from the CAS? If so is it recommended.
3. Also, some of my user mailboxes will be hosted in Zimbra so Exchange 2013 will be internet facing and Zimbra will be side by side for the same (domain.com). Zimbra and Exchange will be using a single DC where all users are placed. So If i need to route the mails to zimbra users, what is the best approach.
TIA...
