Fix Azure SQL Session Limit Reached Error in Microsoft Access
Question details
Users experience a 'database session limit reached' error when connecting Microsoft Access to Azure SQL due to unclosed sleeping sessions.

- Product
- Microsoft Access / Azure SQL
- Device & OS
- not provided
- Scenario
- Connecting a Microsoft Access application to an Azure SQL database for data querying and management.
- Observed behavior
- Microsoft Access generates multiple sleeping sessions that fail to clean up automatically, eventually returning an error stating the database session limit has been reached.
Ensure you have an active internet connection to download official Microsoft Office updates, and temporarily save any unsaved work in your Access databases before proceeding.
Install the Latest Microsoft Office Update
Updating Office to version 2408 (build 17928.20156) or newer officially resolves the bug causing Access to fail at cleaning up sessions.
Microsoft identified a known bug in certain versions of Microsoft Access that prevented proper cleanup of database sessions. By installing the official patch provided in the latest Microsoft 365 update, the background MSACCESS.EXE processes will correctly close, preventing Azure SQL session limits from maxing out.
Launch Microsoft Access on your computer. If you cannot open a database due to the error, simply open a blank database.
Click on 'File' in the top-left corner of the application window, then select 'Account' from the menu on the lower left side.
Under the Product Information section, click on the 'Update Options' drop-down button and select 'Update Now'.
Allow Microsoft 365 to download and apply the updates. Verify that you are updated to at least version 2408, build 17928.20156, and then restart Microsoft Access.

Force Close Hanging Access Tasks
If you cannot immediately update Office, manually terminating hanging MSACCESS.EXE processes acts as a temporary workaround to free up database sessions.

Frequently Asked Questions
What is Microsoft Access Error 3048?
Error 3048 typically displays the message 'Cannot open any more databases.' In affected Microsoft Access versions (like early builds of 2408), this accompanies hanging background tasks that fail to release Azure SQL connections, ultimately hitting session limits.
How do I check my current Microsoft Access version and build number?
Open Microsoft Access, click on 'File', navigate to 'Account' on the left sidebar, and look under the 'About Access' section. Here you will find your version number and specific build number.
Will ending the MSACCESS.EXE task manually corrupt my database?
If you have completely closed your active interface and the process is merely 'hanging' in the background as a sleeping session, terminating it via Task Manager is generally safe and will not corrupt your Azure SQL database.
How can I monitor sleeping sessions in Azure SQL?
You can monitor active and sleeping sessions by connecting to your Azure SQL database via SQL Server Management Studio (SSMS) and running a query against the `sys.dm_exec_sessions` management view.
