Outlook-iPod problem with sync contacts

[maglinders]

(XP, all legit licensed software, full Office suite, latest iPod 50Gb, latest iTunes)

(Outlook, not Outlook Express)



iTunes will not sync/export recently added Outlook Contacts nor any Outlook Calendar data whatsoever. It used to work fine but now something's wrong. (Music, videos and photos sync fine.)

Both Contacts and Calendar from Outlook are checked in the Summary screen.
The sync progress box says it's doing it, but it's only taking over the same old data, not the recently added/updated.

I have restored the iPod settings from scratch as advised. No help.

I have tried with 'enable as disk' and without - makes no difference.

Outlook keeps collapsing when iTunes is running:.

The Outlook icon remains in the systray but if clicked gives the warning 'Application failed'.
Outlook then does not appear in 'Apps (running)' although OUTLOOK.exe remains listed in 'Processes (running)'.
I have to stop OUTLOOK.exe in Processes and when it's restarted it needs to rebuild the Personal Folders.
Sometimes, iTunes says Outlook needs to be closed down and restarted. That means I have to go into Task Manager to turn Outlook off, etc. (as above).

Seems to be some sort of newly-arisen conflict between Outlook and iTunes, and neither Help book can, er, help. If anyone here can, I'd be grateful.

Thank you.
