Function Open Folder Failed error message

[orgullodemexico]

I am using Win XP and MS Outlook on my PC.

Handheld OS 4.5 from TMO
Desktop Manager 4.3.017

Today while syncing my BB 8320 I received an error message "Function Open Folder Failed Message"

I have successfully used this BB and PC/Outlook in the past but have not synced in a couple of weeks.

Any help/ideas?

Thanks
