Did you know that partial indexing in Microsoft Purview is a silent eDiscovery risk? Shelley Bougnague of Cloudficient discusses that here!

As discussed in her post titled (wait for it!) Partial Indexing in Microsoft Purview: A Silent eDiscovery Risk (available here), Shelley discusses how partial indexing occurs when Microsoft Purview cannot completely process a file due to technical limitations related to size, complexity, or time constraints. In these situations, the system indexes only the portion of the file it was able to process before reaching those limits.

For example, parsing time limits of 30 seconds can prevent complex files from being fully indexed. Also, Excel files larger than 4 MB cannot be completely indexed.

It’s as if only the first half of a book scanned and indexed – if a word appears on a page that was never scanned and indexed, the search tool will report that the word does not exist in the book, even though it actually does.

From an eDiscovery perspective, this creates a major problem. Legal teams rely on search tools to locate relevant evidence quickly and accurately. If a file is only partially indexed, critical information may exist inside the document but remain undiscoverable through normal search queries.

So, what attachment limits, parsing timeouts, and excel size caps cause partial indexing in Purview? How does partial indexing affect search accuracy in Purview? And how can you address partial indexing challenges? Find out here, it’s only one click! This blog post is fully indexed! 😉
