Outlook's safe mode will disable both add-ons and COM add-ins
(extensions). However, not all extensions might be listed in the COM
Add-in Manager inside of Outlook. If Outlook runs properly in its safe
mode, an add-on or extension is causing the problem. If all add-ons are
disabled and Outlook is started normally and the problem appears, it is
an extension causing the problem.
Outlook's safe mode disable *both* add-ons and extensions (COM add-ins).
Disabling all add-ons and starting Outlook normally will still have the
extensions enabled.
If disabling all add-ons and starting Outlook normally gets rid of the
problem, start enabling the add-ons one at a time. Enable one, restart
Outlook, and retest. Repeat for each add-on until the problem
reappears. The prior reenabled add-ons is the culprit.
If it is an extension causing the problem, you can do the same
enable-one-at-a-time testing that you did with add-ons. However, if all
add-ons and COM add-ins (that are listed) are disabled when you start
Outlook normally and the problem remains then the problem is with an
extension not listed in Outlook. You'll have to look at Add/Remove
Programs to see what software interrogates the e-mail traffic or
modifies or adds to Outlook's behaviors. For example, AttachmentOptions
from Slovak doesn't show up as a COM add-in, so to get it out of your
environment during testing means having to uninstall it.
Any file indexing program can lockup the database file(s) used by
Outlook. That includes Microsoft's Search. Uninstall it to see if it
causes the problem, or configure it to NOT include indexing of e-mail
contents. Then retest.
What anti-virus software is used by this problematic client? Have you
tried disabling the extraneous e-mail scanning in the anti-virus
software? Sometimes that is not sufficient (as the e-mail traffic will
still pass through their traffic proxy) and you have to uninstall the
anti-virus software and then do a custom install where to deselect the
e-mail scanning feature. Some anti-virus products work like a mail
server rather than a transparent proxy: they accept the e-mail as though
the server or client had accepted it, interrogate it, and then pass it
on. Also check for anything else that interrogates this user's e-mail
traffic, like anti-spam and anti-malware programs.
