Can Microsoft Access handle multiple users?
Access can support multiple users when the application is designed and deployed correctly, but practical capacity depends on data volume, concurrency, network quality, and how much work each user performs.

What this means in practice
A split database with local front ends is the minimum good practice. Forms should retrieve only necessary records, edits should be short, and long-running processes should avoid locking shared data.
The practical next step
When concurrency, remote access, security, or availability becomes more important, moving shared tables to SQL Server, Azure SQL, or Dataverse is usually more dependable than stretching a file-based back end.
This answer provides general guidance. The right recommendation depends on your application, data, users, licensing, and business requirements.
