I am having the same problem. I have tried: 1. Partner box = partner's user name + Title box = user name, and 2. Partner box = partner user name + Title box = partner's actual name, and 3. Partner box = partner's actual name + Title box = partner's user name, AND 4. Both boxes = partner's actual name It should not matter which browser is used. If you can log in, then it should work for cc editing. I find it rather disconcerting that BBO's help "desk" or "help" web site can not answer this issue. It looks like BBO is depending on us users to figure out the solutions to their software problems. Does anyone know how to correct this situation? Without having to redo the editing in M/S Edge. Thanks
