Prevent Security Alert appearing when Outlook 2007 starts

Hi,

I have a small company domain where users now get a security alert appearing when the start Outlook in the morning.  This appears to be linked to the installation of a new Thecus NAS N2200 Plus drive as I can remove the problem if I switch the new drive off.  We have another N2200 Plus drive which has not generated any similar issues.  

Outlook is hosted externally with Intermedia.

The security alert error is ' The name on the security certificate is invalid or does not match the name of the site'.  The general details of the certificate are all thecus specific:

Issued to: N0204.thecus.com
Issued by: dummy_ca.thecus.com

Only one client is mapped to the new drive and the remaining clients aren't however all recieve the alert.  There is no DNS record for the new drive.

The certificate cannot be successfully installed and does not appear anywhere after trying this.

Any ideas appreciated.

Thanks

Do the Users have Personal Folders which are being stored an accessed via outlook on this Drive?
If you close their Personal Folders in their OUtlook Profile
Close and re-open outlook, do you still get the error?

Using Outlook you are trying to connect to the mailbox with HTTPs (outlook-anywhere correct?)

If yes, what is the URL you profile for Outlook to connect with HTTPs protocol
Check if in your device you can by-pass this URL without applying any of the SSL settings\rules etc

So the question is why is outlook trying to access this device on open?

Is it possible users are archiving their email to this device?
Or possibly that they have Cached Exchange mode on, and the ost is being stored in a location on the device?

This turned out to be resolved by a firmware upgrade to the NAS drive.  All my investigation prior to this didnt determine the underlying cause.

the NAS devices, does it takes-up any certificates?
Does this device provides any SSL-Offloading or SSL-bridging before the ssl traffic reaches the Exchange Server
