This error is caused by large embedded files on any page that exceeds the file size limit of your SharePoint configuration. To resolve this problem, you'll need to either split your embedded files across different pages or change the file size limit of your SharePoint server.
OneNote notebooks that are stored on a SharePoint server are subject to a file size limit that is set by the SharePoint administrator. When the total size of any embedded files on a notes page exceeds the SharePoint file size limit, the error "jerrcStorageUrl_HotTableFull (0xE0000794)" appears.
Note: In a few cases, going over the size limit may not immediately trigger the error. Depending on your frequency of OneNote usage, the error may be caused by files that were added a while ago.
To resolve this issue, you need to split the embedded files across different pages in your notebook.
Do the following:
Open the notebook in OneNote 2010.
Click File, and then click View Sync Status.
In the Shared Notebook Synchronization dialog box, click the Errors tab to identify the notebook section that’s causing the error.
Return to your notebook and then navigate to the section causing the error.
Within that section, find all of the pages that contain large embedded files and then separate these files across different pages within the section. (You can easily identify large embedded files on your pages by hovering over the icons of embedded files. A tooltip will display the file size of each item.)
Note: This issue may also be caused by a single large embedded file — for example, if you try to upload a 500 MB video file, while the limit enforced by your SharePoint server is 200 MB. In such cases, you will not be able to resolve this error by yourself. Contact your SharePoint administrator about increasing your file size limit.
OneNote 2010 maintains versions of your pages which may continue causing errors even after the embedded files have been moved or deleted. To resolve this, remove all previous versions of the page by doing the following:
In OneNote 2010, click the Share tab.
Under Page Versions, select Delete all Versions in Section.
This will delete all previous versions that may cause errors, and it will retain only the current version of the page.
Note: In some rare cases, the HotTableFullerror could be caused by issues other than the ones listed in this article. If your error is not resolved by following the preceding steps, please report the details about your issue in the OneNote forums on Microsoft Answers.
If you have SharePoint administrator privileges, you can change the Maximum Upload Size in SharePoint by following these steps:
In SharePoint, go to the Central Admin page.
Navigate to Web Applications Management, and select your server.
Select General Settings.
In the dialog box that opens, you can edit the value of the Maximum Upload Size field.
