Fix Access Crashing When Canceling Email Macro
Question details
Microsoft Access freezes or completely crashes when the user cancels an email macro by closing an unsent message while the Navigation Pane is hidden.
- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- Running an email macro with the Navigation Pane hidden and attempting to cancel the action by closing the unsent email window.
- Observed behavior
- The Microsoft Access application freezes and stops responding to any user input, requiring a forced restart of the program.
Before altering file extensions or performing macro tests, ensure you have created a backup copy of your .accdb database file to prevent accidental data corruption.
Test the Database in Runtime Mode and Isolate Macros
Run the database using the runtime switch or the .accdr extension to isolate whether the crash is caused by UI elements like the Navigation Pane.
By simulating runtime mode, you can strip away the standard Access UI elements to determine if the crash is tied to the Navigation Pane's visibility state.
Test the database's startup function separately from the email macro, as customized default settings might be causing the conflict.
Create a copy of your database file and rename the extension from .accdb to .accdr. This forces Microsoft Access to open the file in runtime mode without changing internal database contents.
Alternatively, launch Microsoft Access from the Windows Run dialog (Win + R) using the /runtime switch followed by your database file path.
Trigger the email macro in runtime mode and cancel it to see if the application still freezes.
Toggle the Navigation Pane Visibility
Since the crash specifically occurs when the Navigation Pane is hidden, temporarily unhiding it during the macro execution can act as a workaround.

Frequently Asked Questions
Does changing the .accdb extension to .accdr corrupt my database?
No, renaming an .accdb file to .accdr does not change its internal contents or corrupt data. It simply tells Microsoft Access to open the file in runtime mode, which is completely reversible by renaming it back to .accdb.
Do I need to install Access Runtime to open an .accdr file?
No, if you already have the full version of Microsoft Access installed on your computer, it will automatically simulate runtime mode when you open an .accdr file. You do not need to download the separate Access Runtime installer.
How can I manually hide or unhide the Navigation Pane in Access?
You can quickly toggle the Navigation Pane by pressing the F11 key on your keyboard. Alternatively, you can click the small Shutter Bar open/close arrow button located on the edge of the pane.
