Outlook 14.3.2 Update sent emails moving to junk

Morning, Having issues with Hosted Exchange since an Outlook 14.3.2 (130206) update. Emails sents from a hosted exchange (via Outlook desktop) are being moved into the junk folder.

When sending via Apple Mail or OWA all fine, but fall back into junk when syncing with Outlook desktop.

Are there any known issues?

Spec: Mac
Outlook: 14.3.2 (130206)

Thanks,
Andy
