I'm setting SharePoint 2019 on premise with cloud SSA. When doing crawl, most of the files get crawled ok but there are quite some files getting error : This item was not indexed because its security information contains complex ACE types, which are not supported." Has anyone seen same error and have a fix? Thanks.

    Hi JayL, it is pleasure to be able to help you.

    According to our current research, the issue may be related to ACE types not being the default crawled file type.

    You can learn which file name extensions are crawled by default and which file formats are parsed by default in documentation: Default crawled file name extensions and parsed file types in SharePoint Server.

    Best Regards.
