So, when you have tried everything else, here is something that you can try. Ultimately, this resolved the issue that I was having with a excvhange 2007 server. Good luck and happy reading!
Overview
One way calendar synchronization is not working from the BlackBerry smartphone to Microsoft® Outlook®
The following log lines are displayed:

The following error message is displayed when you attempt to connect to the affected BlackBerry smartphone user’s Microsoft Outlook mailbox using a profile that does not have cached Exchange mode turned on:
The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance.
Cause
This issue has multiple causes.
- The public folder store is not loaded.
- The BlackBerry Enterprise Server service account does not have the appropriate permissions.
- The protocol settings in Microsoft® Active Directory® have been set to deny MAPI connections.
Resolution
Complete the appropriate resolution for the cause of the issue.
Cause 1
The public folder store is not loaded.
Resolution
Load the public folder store.
Cause 2
The BlackBerry Enterprise Server service account does not have the appropriate permissions.
Resolution
Verify that the BlackBerry Enterprise Server service account has the same permissions as the mailbox store.
Cause 3
The protocolSettings in Active Directory have been set to deny MAPI connections.
Resolution
Microsoft Exchange 2003 SP2 and Microsoft Exchange 2007 SP1
Complete the following steps:
- Install the Windows 2003 Support Tools if they are not currently installed.
- Open adsiedit.msc.
- Expand Domain [servername.domain.com] then the respective container holding the user object that you want to check the protocolSettings of.
- Right-click a user and select Properties on the context menu.
- Select protocolSettings from the list of properties and click Edit.
- If you see a value of MAPI§0§0§§§§§§ or MAPI§1§1§§§§§§ then MAPI access has been turned off for this user. Remove the value.Note: It can take anywhere from 15 minutes to 2 hours for this change to take effect.
Note: By default the Multi-valued string is blank which means that no value is defined and MAPI access is allowed.
HMC 4.0 and later
If the MPS was used to create the user accounts and mailboxes in a hosted environment then the configuration settings of the front-end application that was used to create the accounts must be changed. The change to the configuration settings makes the required changes to all user accounts that were created using MPS.
