Unable to display folder. Unknown error in Outlook iCloud Contacts

Perplexingly unable to open my iCloud contacts folder in Outlook 2007. Unknown error.

Google search and Apple & MS forums unhelpful.

Sorted by disconnecting Outlook and everything in iCloud Control Panel (with save) then reconnect.

1500+ contacts resurrected. Phew.

 

Update – if this fails, check and repair the PST file as per http://office.microsoft.com/en-us/outlook-help/scan-and-repair-corrupted-outl…

 

Update2 – if all this fails, uninstall (not repair – that doesn’t fix) iCloud and reinstall. Contacts tehn sync to Outlook from iCloud.
