After installing Exchange 2010 Service Pack 2, you may suddenly find yourself deluged with calls from users saying that their iPhone is requesting then to enter a passcode.
The reason for requiring a passcode by default is an important one: cell phones contain a lot of valuable information, both personal and business. If your phone is lost, do you really want other people to have access to that information. With the passcode requirement, you can now remotely wipe clean that lost iPhone.
However, if you insist on disabling the requirement for the passcode, here are the steps required:
- Disable the setting in Exchange Management Console (EMC)
- Delete and re-add the Exchange mail account on your phone
Step 1: Disable the setting in EMC
- Open Exchange Management Console, then click Organization Configuration –> Client Access –> Exchange ActiveSync Mailbox Policies tab
- Right click on the Default policy –> Properties

- Click to UNcheck Require Password –> Apply –> OK

Step 2: Delete and re-add the Exchange mail account on your phone
In addition to making the change in EMC, it will be required to delete your Exchange mail account on your phone and then re-add it.
Deleting your mail account:
- Click Settings –> Mail –> Exchange Mail Account
- If necessary record your current settings
- Turn off the options to sync Mail, Contacts, Calendar, and Tasks
- After turning off those options, you should be prompted to delete your mail account
Setting up your mail account
- Click Exchange –> enter your mail account information
- If you are prompted ‘Cannot verify server identity’, click Continue
- Enter your mail account information
