Hello Everyone, I am having a strange problem, I have Ex 2003 on windows 2003 latest updates and patches. every few days all the events in our public folder calendar disappears and I have to restore from a backup. Has anyone ever run across this issue and does anyone have any idea what could be causing this to occur? Thank You Mark J Morgan No virus found in this outgoing message. Checked by AVG Free Edition.
