Can't sync iPhone with exchange 2010 from outside of LAN
Posted on 2015-02-16
I am in the process of moving from Exchange 2003 to Exchange 2010. I have moved a couple of mailboxes across and got Outlook working ok. I couldn't get my iPhone to sync with Exchange 2010 at first, but got it working by enabling inherited permissions in the User security. Now it works fine when in the office and connected to the LAN via wi-first. However, since I left the office last night I haven't been able to sync. So it seems that it works when it can see Exchange from inside the LAN but not from outside the LAN.
I think there must be a port in the router/modem than I need to redirect. I can probably track that down when I get back to the office this morning, but if I change it to get it working for Exchange 2010, won't that break it for a Exchange 2003?
