If you upload files to SharePoint, then create a new SIT and wonder why the files arent being auto labelled based on the new SIT, it is because when the file(s) are uploaded/created/modified SharePoint indexes them and their contents are evaluated against existing SITs. The files are not reindexed when you create a new SIT unless the file is modified again, so your auto-labelling policy doesnt realise the test files contain the new SIT.
To fix it you have 3 options.
- Try modifying some of the test files and see if they then are auto-labelled soon afterwards.
- Run a reindex of the test SharePoint site which will force SharePoint to update its knowledge of what these files contain.
- Use Purview's On-demand Classification tool. It requires PAYG billing to be setup which you wouldn't do for a test environment, but it could be useful if you had a lot of legacy (project?) files that are no longer being accessed but you wanted them to be labelled.
Hope this helps.
