Error resetting last modified date
Hi! I am using CSOM to change SharePoint Online files and reset the last modified date of their items. It works, when I log in to SharePoint with user name and password. When I create an app registration and use MSAL to get a token through interactive login, the reset of the last modified date will not work. The code is the same. It is just the token, that makes the difference. The app registrations API permissions are set to AllSites.Manage, so it should have enough rights to change meta data. Any suggestions what I could change? Cheers Alex
SharePoint Guest Users API Access - Unauthorized
Hello, we've build an Azure AD App that uses MSAL to authenticate against SharePoint. The auth flow works fine, till we try to access SharePoint resources with guest users. We've tried several solutions and configurations but we always get the answere: "Exception of type 'Microsoft.IdentityModel.Tokens.AudienceUriValidationFailedException' was thrown." Is there any policy that does not allow guest users to access sharepoint through the sharepoint api? Direct access to sharepoint works without a problem. Thanks in advance Michael
