Dirsync not working after OU name changes and moves

Hello,

I have a Hybrid Exchange configuration with DirSync and ADFS. Recently I have changed the names of some OUs and reorganized those OUs by moving them to math my organization's hierarchy.

And now the DirSync does not seem to work.

When the Forefront Identity Manager runs the sync Jobs no relevant errors are reported. Nevertheless, the new active directory users does not sync with office 365 the way the used to.

Any ideas?

Thanks
