Depending on what your requirements are and what you wanting to spend there are two options available to use:
1) BIS (Blackberry Internet Service) – Local application built into the Blackberry (No costs involved)
2) BES (Blackberry Enterprise Service) – Special software for Blackberry (Costs involved)
Note: While setup instructions are provided below, Google Apps IMAP1 access is not officially supported for BlackBerry devices at this time.
First you need to ensure IMAP is enabled on your Google Apps account by performing the following steps:
To enable IMAP in Google Apps
1. Sign in to Gmail.
2. Click Settings at the top of any Gmail page.
3. Click Forwarding and POP/IMAP.
4. Select Enable IMAP.
5. Click Save Changes
To set up the BlackBerry’s email client with Google Apps email (IMAP), just follow these steps:
1. On your BlackBerry device, navigate to your home screen
2. Select the icon that lets you set up email (this can be called Setup, Setup Wizard, Email Setup, BlackBerry Set-up, E-mail settings, or Personal Email Set-up)
3. Follow the setup instructions provided on your device to create a new e-mail account
4. Be sure to enter the following:
o Mail Server: imap.gmail.com
o Username: [your full Google Apps email address]
o Password: [your Google Apps password]
o IMAP Port: 993
5. Allow the system to add your account, but do not enter your Google Apps password into the utility boxes (this causes the system to default to POP3 instead of IMAP)
6. Select Next
7. Select Next again (bypassing the ‘Additional Information Required’ section)
8. Select your account type, then select Next
You may encounter a ‘We were unable to configure…’ error. Select I will provide the settings to continue
9. Select the option that mentions ‘IMAP/POP’
10. Select I will provide the settings…, then select Next
11. Select Set up existing email account…
12. Enter your Google Apps account information here, with ‘imap.gmail.com’ as your mail server
13. Select Next
14. Select Save
If setup is successful, you should receive a confirmation message and a new mailbox icon should appear on your device’s home screen, labelled with your Google Apps email address.
If you encounter a problem during setup, please make sure you have enabled IMAP in your main Google Apps Mail settings.
