No, it has no impact on your delegated admin users.

You can use Azure Active Directory (Azure AD) groups to grant access to environments. In the Business Central Admin Center, you can associate an Azure AD group with an environment. Members of that Azure AD group will be synchronized to Business Central and granted access to that environment. These users must have a valid BC license associated.

The main benefits will be:

• Users can only see the environments that they have access to.
• Only the users in the associated group are imported to the environment.

AppSource apps installed on a tenant are automatically upgraded by Microsoft on each major release. Between major releases, you can update an AppSource app by going to the Admin Center Apps section. Here you can see if an update is available and then update the app with a click. With v19, also dependencies will be updated automatically (new Admin Center feature deployed in these weeks).

Upgrade of existing SaaS tenant is in progress these days. You should receive an email that alerts you that an update is available in the upcoming days (if not yet received). New customers and new tenants will be automatically deployed on v19.

No, you can also connect Business Central on-premise to Onedrive. However, there are a few things to do to make it work.

To prepare Business Central on-premises for connecting to OneDrive.

Add a registered application for Business Central in the Azure AD tenant of your Microsoft 365 plan. Like other Azure services that work with

Business Central, OneDrive requires an app registration in Azure Active Directory (Azure AD). The app registration provides authentication and authorization services between Business Central and SharePoint, which is used by OneDrive.

Configure the registered application with the following delegated permissions to the SharePoint API:

• AllSites.Write
• MyFiles.Write
• User.Read.All

You do this work in the Azure portal. Be sure to copy the Application (client) ID and client secret used by the registered application. You’ll need this information in the next task.

To set up the connection in Business Central on-premises choose the icon, enter Microsoft SharePoint Connection Setup, and then choose the related link.

In the Description field, enter a description for the connection, like OneDrive.

In the Folder field, enter Business Central.

In the Location field, enter the URL for your OneDrive.

The URL for a OneDrive is usually in the following format:
https://-my.sharepoint.com. For more information, see OneDrive

URLs for users in your organization in the OneDrive documentation.

In the Client ID field, enter the client ID from your application registration.

In the Client Secret field, enter the secret from your application registration.

Please remember the following: The SharePoint Connection Setup page is used to configure multiple legacy features. The General section configures the connection to OneDrive, and the Shared Documents section redirects files to SharePoint instead. The legacy SharePoint feature will be deprecated in the near future. We recommend that you do not configure the Shared Documents section.
