Question details
Users are experiencing intermittent saving failures in Excel when VBA macros are enabled following a Microsoft 365 update.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to save a macro-enabled workbook (.xlsm) after updating to a newer Microsoft 365 version.
- Observed behavior
- The workbook intermittently fails to save due to VBA macro conflicts introduced by the recent update, potentially leading to data loss.
Ensure you have administrative access to your Microsoft 365 account to check your current update version, and create a backup copy of your macro-enabled workbook before attempting any troubleshooting.
Submit a Service Request via Microsoft 365 Admin Center
Since this is a known issue associated with specific Microsoft 365 builds (like version 2311), reporting it directly to Microsoft support is the most effective way to receive specialized guidance.
Microsoft has acknowledged VBA execution and saving issues following version 2311. If standard workarounds fail, Microsoft support can assist with diagnosing the bug on your specific tenant.
Go to the Microsoft 365 admin center and log in with your administrator credentials.
On the left navigation pane, click on 'Support' and then select 'New service request'.
Provide details about the intermittent saving failure occurring with VBA macros enabled, and reference your current Microsoft 365 version build.

Force an Update to the Latest Version
Microsoft regularly pushes hotfixes for bugs introduced in previous updates. Checking for a newer update may automatically resolve the VBA saving issue.
Try WPS Office for Stable VBA Macro Execution

- 3. Run Macros Securely: Enable macros when prompted and continue working on and saving your VBA scripts without interruption.

Frequently Asked Questions
Why do my Excel macros stop working after a Microsoft 365 update?
Updates can sometimes introduce unexpected conflicts or bugs into the application engine, such as those reported in version 2311, which disrupt the execution and saving mechanisms of VBA macros.
How do I know if my Microsoft 365 version is affected?
Open Excel, go to File > Account, and check the version number under the 'About Excel' section. If you are on version 2311 or a similarly reported build, it is likely the root cause of the saving failures.
Is there a workaround while waiting for a Microsoft patch?
Yes, you can try rolling back your Microsoft Office installation to the previous stable version using the Office Deployment Tool, or you can temporarily use an alternative like WPS Office to edit and save your .xlsm files safely.
