can't reply or forward some mails in Outlook 2007

[alm80]

Some of my customers are having a peculiar problem with Outlook 2007. They
can't reply or forward certain mails. When they do it and press "Send"
button, nothing happens. It is also impossible to copy from those mails. The
paste option is not greyed out, but pressing it does nothing. Outlook was
reinstalled, ost file was checked for errors, the whole profile was deleted
and created from scratch. It solved the problem for some time, but we already
recieve complaints that this problem was not solved and while some
problematic mails were fixed, others were not. Does anyone has any idea how
to solve it as I'm running out of options?

On a troubled machine, does it work correctly in Outlook Safe Mode?
Start-> Run; outlook.exe /safe
(note the space in the command)

If it does, it is probably caused by an add-in. Turn them all off and then
enable them one by one until you found the culprit;

Thanks for your quick reply. The problem still exists on safe mode. But it
doesn't when users work through web-access. It looks that there's no problem
with those mails per-se, it just that Outlook interprets them in some
erroneous way for some reason.

But when you recreated the mail profile, the emails that had issues then
work correctly?
Do you perhaps have a virus scanner installed which integrates itself with
Outlook? Uninstall this integration part of your virus scanner (disabling it
is often not enough) and then rebuild the cache file (ost-file). See if the
issue stays away now.

You'd still be sufficiently protected by your on-access scanner part of the
virus scanner. For more details see;
