we have a SBS2011 running with Exchange 2010 (SP3). We have a public folder for contacts. From time to time most of the 640 (aprox.) are deleted and only a few (80 contacts) remain in the folder. This happens sometimes after few days, sometimes after weeks.
The people working with this folder say that say didn´t do anything... I installed exfolders and i can see only 2 deleted items there.
Any Idea ? The users have outlook 2002-2007 (could this be the problem?).
