Is it possible to update the AzureAD user's SignInNames using Powershell ? I tried to update it but it doesn't work out and gives a Bad Request error. No specific error is given.
Let me know if that is possible! Thanks!
According to the AAD graph, the signInNames
could not be set after creating the account, may be it also could not be set via powershell, because if you catch the request of the powershell via fiddler, it essentially call the AAD graph api, too.
