Windows 10: Outlook Email Random Letters & Numbers

    Outlook Email Random Letters & Numbers

    I put Office 365 on my mother's computer under my 365 Home license. She's using as her email and Outlook as her email client on her computer. Outlook wasn't syncing her email I think due to Microsoft switching to Exchange and deleting the account and starting over was supposed to be the fix.

    Anyway I deleted her account but didn't pay attention to the warning I needed to back something up... maybe not smart. I created a new profile entering her name Pat C and email I'll call

    Her new profile syncs plus sends and receives email just fine... but something's weird going on. Inside of Outlook it lists her email address as gobbledygook it's something like instead of I've already deleted the profile but I believe the profile itself listed it as but if you looked at the Properties of the account it listed it as The gobbledygook numbers & letters aren't exactly as they were listed but you get the picture.

    I tried creating new Profiles plus doing an Office Repair but I always get the same random number & letters for her email. Nor do I ever see this gobbledygook during the setup process... only after it's finished.

    Anyway to fix her email when using Outlook... her email is fine outside of Outlook?

    Hi mccoady

    I think this is your issue, at least it sure looks like it is. Hopefully the fix actually fixes it. email account appears as "outlook_[long series of letters and numbers]" in Outlook for Windows - Outlook

    Thanks Ken you may have found the solution! I logged into my mother's account per the instructions and did see she had an old email address as the primary alias. I made her new email as the primary and then deleted her old one. Kind of strange though because this exact setup always worked before with Outlook... at least until I deleted her email and then tried to add it back in.

    Anyway thanks for the link I'll try to add her email back to Outlook when I get a chance and see how it goes.

    Hi Mike

    Great. You saw on that notice, a known problem since November of last year. Must be something seriously wrong to be open this long. I've done the disconnect and reconnect twice, on MS's request no issues.

    Good luck.
