E2k7 and Entourage

We have an issue with Entourage 2008, it was working fine when we had the account on E2k3 but ever since we migrated to E2k7 Entourage stopped working.

I’ve been searching online for a solution but so far we haven’t found a solution.

Has anyone migrated to E2k7 and successfully setup Entourage?

Thank you.
