Summary
Microsoft Exchange Server 2007 Service Pack 3 is supported on Windows Server 2008 R2. However, the Collaboration Data Objects for Exchange Server (CDOEX) feature cannot work properly on Windows Server 2008 R2.
On machines installed with only the Exchange 2007 mailbox role, SMEX uses the CDOEX feature to send notifications, alerts and reports, and to resend quarantined messages. As a result, the Windows Server 2008 R2 machine, installed with only the Exchange 2007 mailbox role, is unable to send the notifications and to resend the quarantined emails.
Details
To resolve this issue:
- After installing Exchange 2007 SP3 on Windows 2008 R2, install the following Microsoft hot fix:
- Unregister and then re-register CDOEX using the commands below:
"regsvr32 /u [System Driver Letter]\Program Files\Common Files\Microsoft Shared\CDO\cdoex.dll""regsvr32 [System Driver Letter]\Program Files\Common Files\Microsoft Shared\CDO\cdoex.dll"For example:"regsvr32 /u c:\Program Files\Common Files\Microsoft Shared\CDO\cdoex.dll""regsvr32 c:\Program Files\Common Files\Microsoft Shared\CDO\cdoex.dll"
- Reboot the server.
