Sync Issues with OneDrive due to Mac/iOS Contact Database Metadata file

Hi,

I have the OneDrive app for my Mac Powerbook, and receive sync issues due to invalid characters for a Mac Contacts (.abbu) database. It seems over 2700 metadata files have an invalid character and I need to manually rename them. But how do I do that to the metadata file in a database?

The metadata file name in OneDrive states a colon ':' as the invalid character, but in my Mac Finder, the same filename is displaying a backslash '/' instead of a colon.

I understand that both characters are invalid for OneDrive, but if I change the invalid character in the Contact DB, will it impact my contacts?

Thanks in advance.
