How to Fix Access Split Database Path Errors with SharePoint
Question details
The user needs to resolve path errors and unreliable multi-user performance caused by storing a shared Access backend (ACCDB file) in a synchronized SharePoint folder.
- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- Sharing a split Access database across multiple users using a synchronized SharePoint document library.
- Observed behavior
- Using a synchronized SharePoint folder for an ACCDB file causes incorrect path errors, file conflicts, and essentially creates a single-user setup instead of a reliable multi-user backend.
Before making structural changes to your database, ensure you have created a local, unsynchronized backup copy of your ACCDB file.
Migrate Access Tables to SharePoint Lists
This is the recommended approach for integrating Microsoft Access with SharePoint, allowing true multi-user data entry without file sync conflicts.
Placing an ACCDB file directly in a SharePoint document library relies on file synchronization, which downloads local copies for each user and prevents simultaneous data editing. By migrating your tables to SharePoint Lists, the data is hosted on SharePoint's servers natively, and the Access front end simply links to these lists for real-time multi-user updates.
Launch Microsoft Access and open the database containing the tables you wish to share.
Navigate to the 'External Data' tab on the ribbon. In the 'Export' group, click 'More' and select 'SharePoint List'.
Enter the URL of your SharePoint site in the export wizard and follow the prompts to upload your tables as lists.
Open your Access front-end file. Go to 'External Data' > 'New Data Source' > 'From Online Services' > 'SharePoint List', and link the newly created lists.
Upgrade the Backend to SQL Server
If SharePoint Lists cause SQL coding errors or if your database is large and complex, SQL Server is the most robust solution for a shared backend.

Frequently Asked Questions
Why can't I just sync my Access ACCDB file via OneDrive or SharePoint?
Syncing an ACCDB file via SharePoint or OneDrive downloads a local copy to each user's computer. When changes are made, it results in file sync conflicts, lockouts, and overwrites, rather than real-time multi-user data sharing.
Are there size limits when using SharePoint Lists as an Access backend?
Yes. While SharePoint can store millions of items, Access performance can degrade significantly if a linked list exceeds the SharePoint list view threshold (typically 5,000 items) without proper indexing.
What should I do if exporting tables to SharePoint causes SQL coding errors?
Complex table relationships, unsupported data types, or advanced SQL queries may break during the export to SharePoint Lists. In these cases, it is highly recommended to upgrade to a SQL Server backend, which natively supports complex relational database features.
