Configuring Exchange Access on the iPhone
Configuring Exchange on my iPhone was a little bit of trial and error. Here’s how I did it using my server info.
Go to your phone settings.
Mail, Contacts, Calendars
Select "Mail, Contacts, Calendars."
Select "Add Account…"
Select "Microsoft Exchange."
When the settings screen first appears, it will simply ask you for your email address, username, password, and description. Then it will take this information and try to auto-configure Exchange, but it will fail. At this point, the server setting will appear and you can enter your server. Since the iPhone’s Exchange connection uses the same protocol exposed by Outlook Web Access, that server must be entered here. The settings, then, are as follows:
Email: your full email address
Server: your Outlook Web Access server (owa5.intermedia.net for my workplace)
Username: your full email address (for my workplace)
Password: your account password
Description: anything can go here; this will appear in Mail in your account list
Here you can choose which items will be "pushed" to your iPhone. In most instances, you will choose all of them, but the option to turn off any one of them is available.
Main ActiveSync Settings
Once configured, you can access the main account setting screen. You’ll want to decide how many days/weeks worth of emails to store on your iPhone. The more you store, the more disk it consumes.
Account Info Settings
Here is another screenshot of the Account Info settings, most of which we saw before. Take note of the "Use SSL" toggle.
