Re: Outlook 2007 cached mode registry keys

[Benjamin Gay [MSFT]]

Is there a way to adjust Outlook 2007 cached mode timing?

In Outlook 2003 we can:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Outlook\Cached
Mode
registry key:

- "Upload=dword:0000000f" (default is 15 seconds).

- "Download=dword:0000001e" (default is 30 seconds)

- "Maximum=dword:0000003c "(default is 60 seconds)

but, I don't seem to find any reg keys in Outlook 2007

Thanks

Have a look at the Office 12 Group Policy ADM templates available at
http://www.microsoft.com/downloads/...4B-7112-4B6C-AD4A-BBF3802A5C9B&displaylang=en

As you can see from the following snipit of outlk12.adm all of the items
are supported:

POLICY !!L_Entersecondstowaittouploadchangestoserver

Hi Jennifer,
Are you saying that you are setting your cached Upload, Download and
Maximum values to 2 seconds? Personally I have never set them this low,
but imagine that this would not be very performant.

Is there a specific reason why you are setting these values so low? What
issues are you seeing with setting this so low?

We are using EMC Extender to shortcut our attachments. In cached mode when
a user clicks on an email the attachment gets pulled back into exchange -
because of the 15 sec upload setting users would have to wait to open the
attachment. EMC has a KB article that suggest to bring just the upload time
down to 2 seconds. Ever since we put this in place we have gotten sporadic
reports of emails being delayed. Over the past few months this has been
more and more prevalent. I have put several facts together and it seems
cache mode is causing this issue. I want to prove it though and today I was
allowed to take cache mode off of one user's mailbox. It seems that when
users send an email (randomly) it is not in their outbox nor in their sent
items folder. Every time the email eventually sends the user has logged
into terminal server or OWA just minutes before it sends. The odd thing is
they can send emails before and after (even to the same people) with no
issues. I cannot seem to figure out what in the world is going on. Now
some users are on HIGH alert since they are having emails delay for many
weeks (the amount of time it take for their next log into OWA or terminal).
This has made it a little easier (lately) to get some more info. Once the
email finally sends I can track it in exchange and it shows that exchange
gets it just before it sends it. When I look at the senders sent items
folder the email appears with the original sent time stamp. This problem is
driving me crazy. I need to find out what the problem is and get it
resolved.
