Subject: [ExchangeList] Outlook 2007 issue
Just wondering if anyone is experiencing this. Users keep losing the ability to autocomplete addresses within Outlook 2007. I have seen a few post around, talking about corrupt profiles, but if this occurs so often, shouldnt MS offer a patch? or is there one out there. I hear even after creatin a new profile this issue re-occurs.
