Adobe Acrobat's PDFMaker Add-in to Outlook disables program's normal
operation.
PDFMOutlook add-in can be removed via the Trust Center menu in Outlook Tools
menu (under COM Add-ins). If permissions not properly set in Office 2007, the
add-in cannot be removed and you receive the inscrutable message "The
connected state of Office Add-Ins registered in HKEY_LOCAL_MACHINE cannot be
changed." Permissions can be changed by right-clicking the Office 2007
program icon in the Start menu and selecting Properties, then Security, then
Edit Permissions. After PDFMOutlook was removed by this procedure, my Outlook
2007 crash problems seemed to be resolved.

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.
