I never have this error before & just about 3-4 days ago it surfaced:
whenever I click on "New" (ie to create a new Message) or try to
"Reply" or "Reply All" to reply to an email (this is also in a way
creating a new email), Outlook 2003 (running on my Win XP
Professional SP 3 laptop) would throw out the attached message.
I followed one instruction in url below & it helped for a while ie
I could create/reply email (but somehow some of the Personal
Folders went missing but I just have to create a new pst file &
point back to the .pst files on my local drive) :
Goto Tools > Options > Other tab > Advanced Options > "Add-In Manager" and remove (uncheck) all non native AddIns & click OK. Also select "COM Add-Ins" & uncheck all
options & click OK
I did not have to reboot nor restart Outlook after following the
above instruction but after rebooting my laptop, the same issue
resurfaced, ie can't create new email. This time round, I found
that those Add-Ins above are still unchecked.
I've also googled which suggests to remove an MS patch but I
don't have that patch installed in my laptop.
I have yet to recreate the Outlook profile (another suggestion)
Any other solutions?
