Below is the list of features that will be deprecated in future versions:

• Functionality related to Basic Authentication, which is being deprecated by Microsoft 365:
  • Basic authentication for M365 tenants
  • Auxiliary backup accounts
  • Modern authentication that allows for using legacy auth protocols
• M365 Germany region
• Azure Blob Storage Germany region
• SMB-Based Repositories — This functionality was always experimental, and over time it has become clear that the jet-based backup storage system we use does not function efficiently with SMB-based repositories. Additionally, over the years, we have seen fewer and fewer customers each year utilizing SMB-based NAS storage.
• Auxiliary backup applications (from unlimited to a limited number)
• Support for on-premises Microsoft Exchange and SharePoint
