While I'm trying to "Sync a New Library" from SkyDrive Pro to SharePoint Online I'm facing the below error
"We Couldn't set up this library for you because of a server or list configuration problem. If this keeps happening, please contact your administrator. Once this issue has been resolved you can try setup again."
Technical Details: Unspecified error
Error code=0x80004005; Error source=Groove.

This problem happens suddenly. We have other users who have already synced this document library and has no problems. Users who are trying to sync it first time are now facing this above error.
Please help.
Thanks.
