I have just installed a Sonicwall TZ 205. Before installing this firewall everything was working fine. We are using Exchange 2013 on Windows Server 2012 R2. I now have it set up and I can send and receive email from the PCs Outlook on the network but now I cannot connect with mobile devices. I included IMAP, POP 3, HTTP, HTTPS and SMTP in the service object for email services. Is there another step I am missing?
