Consider the following scenario:
- You have a Microsoft Exchange Online mailbox user account.
- You have an Android phone that supports Exchange ActiveSync.
- When you add the mailbox account on the phone, you input a Microsoft Exchange Online server name with the https:// prefix in the Server field. For example, you input “https://red001.mail.microsoftonline.com” (without quotes) in the Server field.
In this scenario, you cannot click the “Next” button to proceed with the configuration.
Remove “https://” prefix. For example, just input “red001.mail.microsoftonline.com” (without quotes) in the server field. Check the “Use secure connection (SSL)” check box and proceed with the configuration.
Here blow is a list of server names of for Microsoft Business Productivity Online Standard Suite (BPOS) accounts.

This workaround does not work on my Android 2.2 Froyo and my work's Exchange 2010 server. "This server requires security features your phone does not support."
