How to Share Access Database Changes with a Team
Question details
A team needs a reliable way to merge simultaneous changes in a shared Microsoft Access database without encountering synchronization errors.

- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- Multiple users attempting to edit a shared Access database simultaneously using Microsoft Teams or similar file synchronization software.
- Observed behavior
- File synchronization creates data conflicts and overwrites because it treats the database as a single-user file being downloaded and uploaded entirely.
Ensure you have access to a dedicated network shared folder where all team members have read, write, and delete permissions before attempting to configure the database.
Split the Access Database into Front-End and Back-End Files
Use the built-in Database Splitter to separate your data tables from the interface, which is the standard method for allowing simultaneous multi-user editing.
Microsoft Teams and standard file synchronization tools are not designed for simultaneous Access database editing. To allow multi-user data entry, you must split the database into two parts: a back-end containing only the tables, and a front-end containing forms, queries, reports, and VBA.
Launch Microsoft Access and open the existing database file you wish to share with your team.
Click on the 'Database Tools' tab located on the top ribbon menu.
In the 'Move Data' group, click on the 'Access Database' button to launch the Database Splitter Wizard.
Follow the wizard prompts to split the database. Save the newly created back-end file (which contains the tables) to your team's shared network folder.
Provide each team member with a separate local copy of the front-end file. Each user must open their local copy, which will link automatically to the shared back-end data.

Looking for a Lightweight Office Alternative?
Managing network shares and splitting databases for multi-user access can be highly complex. If your team is looking for a simpler workflow for standard documents, consider WPS Office. It provides a free, lightweight alternative for handling Word, Excel, and PowerPoint files with seamless built-in cloud sharing.
- 1. Download WPS Office: Visit the official WPS website to download the free installation package.
- 2. Install the Application: Run the installer and follow the on-screen instructions to set up WPS Office on your computer.
- 3. Share and Collaborate: Open your team's standard Office files and easily share them using built-in cloud capabilities.

Frequently Asked Questions
Why can't I share an Access database directly via Microsoft Teams?
Microsoft Teams uses standard file synchronization that downloads and uploads the entire file upon changes. This creates a one-user-at-a-time process and inevitably generates file conflicts if multiple users try to edit the database simultaneously.
Will users see new queries and updated records in a split database?
Yes, users will see updated records in real-time because the actual data is stored centrally in the shared back-end. However, if you create new queries, forms, or reports, you must distribute an updated copy of the front-end file to each user.
What folder permissions are required for the shared network drive?
All users connecting to the shared back-end database must have read, write, and delete permissions on the network folder. This allows Access to properly create and delete the temporary lock file (.laccdb) required for simultaneous data editing.
