Exchange 2016 migration iPhone settings (Giacom)
After migrating to the latest version of Microsoft Exchange 2016 with Giacom (Messagestream) and even though your outlook connects correctly, your iphone may not pick up the details automatically, which may also affect losing all your named contacts. Once you have deleted your old account on your iPhone, please add new account. Select Exchange then manual sign-in. Where it asks for server enter activesync.giacomcp.com then email address as username and your password. Everything should now get ticked and you will have all your contacts names linked back correctly.
If you need to access your exchange 2016 whilst away from your outlook go to https://webmail.giacomcp.com/.
