I am admin on a Yammer network and if I invite a Guest User (external email) to the Network, the user gets an invite and logs in and can see the Network. The following time (or could be the next day) the Guest user tries to log in but fails and the system has soft-deleted the profile. The description on the account says Former Member. I think the following day the profile doesn't exist at all.
Has anyone got any ideas what might be causing this. Thanks
