External user's login error - "We could not find an account with that username". RRS feed

  • Question

  • Hello Guys,

    We have an application in SharePoint Online and in that we have created a Discussion board. In discussion board we are inviting the external users (like tenant with,, etc.). When invite sent to the external user and user got a notification on their respective email then some of them are able to login and activate their account and some of them are getting error while login on the site (few gmail accounts are working and few are not, all hotmail accounts are working, yahoo account is not working). Could you please let us know that is their any setting available in gmail account or something else?

    Below is the error which is getting while trying with gmail and yahoo account.
