I’ve just finished working on an issue with the folks in Support, relating to PSTDisableGrow. A customer had the key set per :
http://support.microsoft.com/kb/954268
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\PST
When they upgraded the Enterprise Vault Outlook Add-in to 9.0.1, they had a problem whereby opening an archived item gave them just the shortcut. The banner across which when click showed :
The item could not be downloaded. [OIOM] 80070005
There was a change made to the 9.0.1 client to fully utilise the Outlook Object Model. We use that to display items. In order to display an item using the Outlook Object Model you have to have the item in a message store – previously we used an in-memory object. So, we download the item you double click on, and add it to a temporary PST file, and then use the Outlook Object Model to display the item. You can see the problem, I hope! We can create a PST file…. but we can’t “grow” it to put the retrieved message in it.. so errors are thrown in to the client log, and the net result is the item fails to display, giving the end user just the shortcut.
The fix is two fold.
First of all the PSTDisableGrow must be in :
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\<version>\Outlook\PST
Secondly you have to add the key, PSTDisableGrowAllowAuthenticodeOverrides :
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\<version>\Outlook\PST
After that, restart Outlook, everything will work.
Version is 12.0 for Outlook 2007, and 14.0 for Outlook 2010. You can find out the other versions easily enough, and it’s shown in the EV Outlook Add-in client log, if needed.
This information will land in a technote near you, very soon !
