It's all a bit of a mess at the moment. I've back-levelled to an earlier version (18.104.22.16819) and told the app not to look for updates - see https://discussion.e...er/#entry363768. Now it's all working fine again. I have the old reliable icon back in Outlook and can swipe/copy groups of emails again. It'll fall over if I copy too many attachments but that's understandable. AdmitalP, I suggest you do the same until the devs have sorted this out, and even then double check here first to be sure they've done it properly. Use a full restore to be sure you've got everything unless you've used a good uninstaller like Revo. Are there any EV devs reading this by the way? I pay a premium rate and use EN constantly in by business flow. This latest error cost me time, inconvenience and undoubtedly money. It would be comforting to know someone is sorting it out.... Incidentally, I got my back level from Filehippo.com Best of luck.
