Offline Address Book Error Exchange 2010 SP1

Hi,

I was trying to remove the replicas of a public folder of a old exchange server. After doing all steps, I still couldn't remove it. So I deleted it from ADSIEDIT Configuration. Removal went fine.

But since then I get this warning in the event viewer:
