This afternoon we had a serious ldap-backend booboo and we were luckilly been able to reattach all orphaned stores back to the appropriate new storeID's. (round 336 stores in the dirty list).
We lost no mail at all, and the reattach was easy scriptable and very clear in use and fixed it in notime!

Seriously a lifesaver.

Worked like a charm, next thing could we have an "do not create/delete store lock" in Zarafa?
So we can fiddle with our ldap without zarafa thinking it needs to erase all?
