User Query: I’m trying to connect to Microsoft Access database from another application, but it’s not working. I want to know the correct steps and connection string. Also, is it possible to link your data in MS Access from external sources?r?
Summary: Microsoft Access is still one of the most used desktop database management systems for small businesses and internal tools. If you’re building an application, using Excel, or running a script. You’ll often need to connect to MS Access Database to fetch or update records. But connecting to MS Access isn’t always simple. It depends on what version you’re using; it’s 32-bit or 64-bit. In this blog, we’ll discuss using the manual method to connect your MS Access database. Additionally, if your database file is damaged or corrupted, you can use the professional DRS Access Database Recovery Tool.
Why Establishing Connectivity to a Microsoft Access Database?
When we say connect to a Microsoft Access database. It means establishing a bridge between the database (.mdb or .accdb file) and another program (like Excel, VB.NET, Python, SQL Server, etc.). That needs to read, write, or update the data stored in Access. This can be done using:
- ODBC (Open Database Connectivity).
- OLE DB (Object Linking and Embedding, Database).
- Connection strings in scripts.
- Manual linking from MS Access to external sources.
How to Connect to Microsoft Access Database?
You can connect to an Access database from various platforms. Below is a general method using ODBC or a connection string in your app.
Method 1: Using ODBC Data Source (Windows)
- Initially, open the ODBC Data Source Administrator.
- Then, press Windows + S, search for ODBC.
- After that, choose either:
- 32-bit: ODBC Data Sources (32-bit)
- 64-bit: ODBC Data Sources (64-bit)
- Now, depends on your MS Access version.
- Next, add a New DSN (Data Source Name). Click on Add.
- Further, select Microsoft Access Driver (.mdb, .accdb). Click Finish.
- Name Your Data Source. Give your DSN a name (e.g., AccessDB)
- Afterwards, click Select to browse and choose your .accdb file. Save and Test
- Lastly, your DSN can be used in apps like Excel, Power BI, Python, etc.
Method 2: Connect to Microsoft Access Database Using String
If you’re coding or using a script, the easiest way is to use a connection string.
-
For .accdb (Access 2007 and later):
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Path\To\Database.accdb;
-
For .mdb (older versions):
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Path\To\Database.mdb;
- Make sure you have the correct driver installed (either Microsoft.ACE.OLEDB.12.0 or Microsoft.Jet.OLEDB.4.0).
How to Link Data in MS Access?
If you want to link external data into your Access database (instead of importing it). Here’s how to perform it:
- First, open your MS Access database.
- Now, click on External Data from the top menu.
- After that, choose the source: Excel, SQL Server, Text File, or ODBC Database.
- Then, select the Link to the data source by creating a linked table.
- In the end, complete the wizard to finish the linking process.
Common Reasons Access Database Fails to Connect
Connecting to MS Access can fail due to:
- Incorrect or missing driver (ACE or Jet).
- Using a 64-bit app with a 32-bit driver (or vice versa).
- File permission issues (read-only, network restrictions).
- Moreover, a corrupt database file.

Frequently Asked Questions
Ans: There are several reasons your Access database may not connect. Common issues include missing or incorrect drivers (like ACE or Jet), a mismatch between 32-bit and 64-bit applications, or restricted file permissions.
Ans: To link data in MS Access, go to the External Data tab, choose the appropriate data source, and select “Link to the data source by creating a linked table” to maintain a live connection instead of importing.
Ans: Yes, you do. Microsoft Access uses specific database drivers to establish connections.
➡️ For .accdb files (Access 2007+), you’ll need the Microsoft ACE.OLEDB.12.0 driver.
➡️ For older .mdb files, use the Microsoft.Jet.OLEDB.4.0 driver.
Ans: Here are the basic connection strings you can use depending on your Access file type:
➡️ For .accdb files: Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Path\To\Database.accdb;
➡️ For .mdb files: Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Path\To\Database.mdb;
Ans: While the DRS Access Database Recovery Tool is mainly designed for repairing corrupt .mdb or .accdb files, you can still link or migrate your Access data to SQL Server using Access’s built-in options or Microsoft’s SQL Server Migration Assistant (SSMA)
