Hi @SlimJim
I am sorry to hear that you have lost a significant portion of your document's content. To better understand the situation and suggest appropriate recovery options, could you please provide a few more details?
-Is the document saved locally on your computer, on OneDrive, or on SharePoint?
-Was the content lost while the document was still open, or after you closed and reopened it?
-Is the AutoSave feature currently enabled?
First, please try the following steps:
1.Reopen Word and check if the "Document Recovery" pane appears. If it does, open the most recently recovered version and save it immediately under a new name.
Please refer: https://support.microsoft.com/en-us/office/collab-files/recover-your-microsoft-365-files
2.Open the document, then go to File > Info > Manage Document. Look for a version labeled "when I closed without saving," open it, and select Restore.
3.If the document is saved on OneDrive or SharePoint, open it and check the Version History to find the version containing the lost content. Files stored here often retain previous versions, especially if AutoSave was enabled.
You should avoid making further edits to the current document until you have checked all recoverable versions. Unfortunately, if AutoSave or AutoRecover did not capture the lost content, it may not be possible to recover it.
To prevent this from happening in the future, you should save your document to OneDrive or SharePoint and enable AutoSave. Additionally, you can go to File > Options > Save and ensure that the options "Save AutoRecover information every x minutes" and "Keep the last AutoRecovered version if I close without saving" are enabled.
Please keep me updated.
