user: #azTechHelp Hi, I created an app to use for single sign-on to a mediawiki site, internal tenant users can successfully log on, but so can external, for example outside users that we share a sharepoint site with, how to disallow external users?
agent: We’re looking into your question and will have an update for you shortly.  We found some documentation that we think may help with this:
user: thanks for a quick reply, I found that one already, unfortunately it simply disables login for ALL users
agent: No problem. Have you seen this information:
user: I can see that this is a premium (paid) feature that we currently do not subscribe to, how is the number of users calculated for pricing? If for example it is users that exist in our Azure Active Directory, then this will be far too expensive
agent: We recommend filing a free billing support case here: Feel free to keep us updated. Were you able to create a billing support case?
