Out of Office error in Outlook 2007 connecting to Exchange 2003

[apaMark]

Hi,

I've got an issue with our Exchange and Outlook configurations. This issue
is only affecting users using Outlook 2007 when connecting to our Exchange
2003 server. Users still using Outlook 2000/2003 are not affected.

When a user with Outlook 2007 tries to place a OOF on their account, they
get the message 'Out of Office Assistant cannot be displayed', when clicked
OK to another message comes up stating 'System resources are critically low.
Close some windows and try again'. Click OK and it goes back to Outlook.

The OOF can be set by the user from OWA with no problems but still not from
Outlook.

All our users that have Outlook 2007 have this problem, however when I had
the problem with my own account I managed to solve the problem using the
MDBVU32 utility and a walkthrough I found on msexchange.org but at least two
of the other accounts will not respond to this.

After some more Googling, I found references to turning off Cached mode in
the Outlook profile. I have tried this and run the MDBVU32, but am still
getting the same messages.

Has anybody got any suggestions? I'm banging my head against the wall at the
moment!

Thanks,

Mark.

do you use a Proxy Server?

Hi Walter,

We use ISA Server 2004 as packaged with SBS 2003 to control and monitor
Internet access, so yes. It is not used to the full functionality of ISA
Server though, we have a hardware router that does this.

Thanks,

Mark.

Hello Mark,

This probably relates to the fact that Outlook 2007 / Exchange 2007 can have
separate internal and external OOF messages, and when Outlook 2007 connects
to Exchange 2003 it cannot find the capability to have separate messages.
