Dear All,
at our Clients we have Exchange 2013 running and also mobile sync.
all clients were happy with Calendare sync. sadnly everything stops working after firewall update !
we have port 443 allow from WAN to the LAN and Nat it to the exchange.
emails traffic works fine over the phones,
the problem is :
when a client add a meeting on her/his phone calendare it doesn't sync to his outlook/ exchange account, however creating a apointement on his Outlook it sync to his/ her phone
can you please put me on the right direction ?
either its firewall or Exchange configuration ?
do i need to open more ports on the firewall side ?
thank you
julien
