Finally found the solution if anyone comes across this hope this helps:
"After contacting TrendMicro about this problem they told me the problem was
with upgrading from version 7 to version 8'.
The solution they gave me worked and is al follows:
This case is a defect in SMEX VSAPI module.
From the logs that you've provided, the "VirusScanProactiveScanning" keys
under the

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSExchangeIS\<servername>\Pr

were not removed when upgrade from 7.0 to 8.0, and cause proactive scan to
turn off.
SMEX 8.0 does not use this key.
Proactive scan for Exchange store is turned off after upgrade to SMEX 8.0.
Users will not be able to synchronize their e-mails through ActiveSync until
these mails are accessed by mail client or scanned by a background scanning.
To resolve the issue, please do the following:
Step 1: Click on Start > Run and then type regedit
Step 2: Remove "VirusScanProactiveScanning" the key under each
"HKLM\SYSTEM\CurrentControlSet\Services\MSExchange IS\FSSDAM\PrivateorPublic-
<Per DB GUID>\"
Here's the exact location of the keys based on the registry logs you've
given:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSExchangeIS\<servername>\Pr
ivate-3484c833-f074-4793-97a0-0bbbcdbb7c75]

Step 3: Restart SMEX_Master service.
Step 4: (Optional) Perform a Manual Scan when mail traffic is low."
