Hi Jahrl,
May I know if it is happening with a specific PowerPoint presentation? For the test purpose, please create a new PPT and then link some chart from Excel, update the data in Excel and check if the chart resizes.
Besides, please ensure your Microsoft 365 apps are fully updated, sometime updating Office fixes issue. To check version information, open any Office app, such as Excel or Word, click File>Account, check for the info mentioned under Product Information. The latest version of Current channel is 2106 (Build 14131.20332). For other channel version info, see Update history for Microsoft 365 Apps (listed by date)
If the version is not updated as mentioned in the article, please install updates and check if the issue remains. To know how to install updates, see Install Office updates.
If the issue persists,****please provide us with the following information:
- A screenshot of Microsoft 365 Product Information. To get this screenshot, open Word or Excel on your system, click File>Account, capture the screenshot of all the information mentioned under Product Information.
- Your OS version?
- Since when you are getting this issue? Is it after Office or Windows update?
- May I know how you have linked Excel chart to PPT?
