Hi

Thank you all for help. Pooling interval is set to 10min. Have also tried to
run Outlook in safe mode without any differences.
The patch was allready installed on a machine, also there are not Adobe
plugins. PST file is 4 GB large.
Any other ideas what could cause this?

Hi

We're facing with a problem when Outlook 2007 (running on WinXP Pro)
send/receives a mail. During that time, everything freezes (Outlook and
all
other applications in Windows), so users need to wait about 10-15sec to
continue with work.
Have tried to disable all add-ons and antivirus software, but without any
improvements. We don't have any problems with computers that are using
Outlook 2003, problem is only with a new ones (using Outlook 2007).
We don't have an Exchange mail server, so all client accounts are POP3
(mail
server running on Linux).
Any issue how to solve this will be very appriciated.
