Exchange 2007 OAB - Modified Date Not Changing

I was hoping that someone could explain something to me concerning OAB in Exchange 2007.

Under Organization Config > Mailbox > OAB Tab
I right click on the Default OAB and see that the modified date is dated back in May 08.  I can right click the Default OAB and choose update and I get the status message that it was successfully updated and I also check the event viewer on the CAS for EventID 1008 that tells me that the update completed successfully as well but the modified date of the OAB still remains May 08.  Can anyone tell me why that is?

The modified date does not change it just shows when it was created so you dont need to worry.

Exchange caches most of the settings and will take a while for the settings to be updated. Restart the services to refresh the cache.

If that is true why does the documentation that I have mention to check the OAB Generation weekly to ensure that the OAB is being successfully updated.  The documentation then goes on to explain that you need to look at the "Modified Date" following the steps that I explained above? Do you have any documents or links to documents to support your answer?

And if you have web-based distribution go to the Exchange OAB shared folder and chek the .oab file and can you check its modified date.

Rancy,

1. In the PF MMC the OAB Version4 states a modfied date of Tuesday, February 05, 2008 1:48:33 PM.
2. The modfied date for the folder located at "C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB" has a modified date of today at 7:20am.

Where exactly should I look in the PF console for that modified date? As I mentioned above I looked at the OAB Version4 but that must not be the correct location to view the modified date.

If you go in EMC to the toolbox option in the left. You would get an PF console and then in the System folder you would find some entries with the AG names once you highlight you would see the OAB versionns in the middle pane.
In the middle pane go to the properties of the OAB versions and check.

So if you see that the .oab file in the Exchange OAB folder has the newest date. Can you share the article that says that the OAB would have the modified date and where would it show ?
