Optimizing performance for add-ins

Updated on December 21, 2020

To create the best experience for users, ensure that the Office Add-in runs within the specific limits for the CPU core and memory usage, reliability, and, the response time for evaluating regular expressions. These run-time resource usage limits apply to add-ins running on the Microsoft Office clients on Windows and OS X, but not on mobile apps or in a browser.

You can also optimize the performance of your add-ins on desktop and mobile devices by optimizing the use of resources in the add-in. For more information, search for the resource limits and performance optimization for Office Add-ins in the Microsoft documentation.

If any content or task pane add-in exceeds the preceding thresholds on CPU core or memory usage, or tolerance limit for crashes, the corresponding Office application displays a warning for the user. To optimize performance, perform any of the following actions:

  1. Restart the add-in.
  2. Cancel further alerts about exceeding that threshold.

    It is recommended to delete the Add-in. Continuing running the Add-in might risk further performance and stability issues.
