I've just gone through the very painful process of upgrading to Groove 2007 from version 3.1. A whole day lost trying to make it work again when it was fine before. But it is still not working correctly. Only some of my contacts are showing as online. I've gone through the "delete the contact"/"send a message"/"add the contact" process as suggested in the knowledgebase but no success. I can even send messages to the ones who appear offline, but when they reply I do not receive them. Amy ideas? Tony.
