Product: Microsoft Excel
Device & OS: not provided
Scenario: Clicking 'Refresh All' to update data connections and PivotTables in a large workbook following an upgrade to Excel Version 2308.

Solution 1Recommended

Roll Back Office to an Earlier Stable Version

Reverting to a previous stable build of Microsoft Office can bypass performance bugs introduced in the latest update until a permanent patch is released.

Software updates occasionally introduce unexpected bugs, particularly affecting memory management for large datasets. Rolling back to the version installed before the issue started is the most reliable temporary fix.

Disable Automatic Updates

Open Excel, go to File > Account, click on 'Update Options', and select 'Disable Updates' to prevent Excel from reinstalling the buggy version overnight.

Open Command Prompt as Administrator

Type 'cmd' into your Windows search bar, right-click on 'Command Prompt', and select 'Run as administrator'.

Run the Rollback Command

Type '"C:\Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.xxxxx.yyyyy' (replacing the x's and y's with your previous stable build number) and press Enter.

Roll Back Office to an Earlier Stable Version

Build Number Format: You can find a list of previous Microsoft 365 build numbers on the official Microsoft release notes page to identify a stable version released prior to your current build.

Solution 2

Submit a Support Request via IT Administrator

If you are using a managed corporate computer, you may not have permission to roll back updates and will need administrative assistance.

Frequently Asked Questions

Why does Excel take so long to calculate a PivotTable report?

In massive datasets, calculating PivotTable reports requires processing hundreds of thousands of data points. Poorly optimized source data, complex calculated fields, or recent software bugs (like in Version 2308) can significantly inflate calculation times or cause Excel to freeze.

Will refreshing a massive PivotTable in Excel freeze my entire computer?

Excel may appear unresponsive and display a 'Not Responding' message while it dedicates your computer's CPU resources to update fields. It is recommended to wait a few minutes, but if it hangs indefinitely, you may need to force quit the application.

How do I share a broken Excel workbook with IT without leaking sensitive data?

Create a duplicate of your workbook and sanitize it by replacing real names, financial records, and proprietary information with dummy data or randomized numbers before sending it to your IT department or Microsoft Support.

How can I stop Excel from automatically updating to a buggy version again?

Open any Microsoft Office application, navigate to File > Account, click the Update Options drop-down menu, and select 'Disable Updates'. Remember to re-enable them periodically to check if Microsoft has released a permanent fix.
