I very much prefer Outlook's indexing compared to Sharepoint's shitty UI and search capabilities.

I mean, yeah if your choice is between Email or SharePoint, email wins every time.

But I've seen enough corrupted PST files in my days to never trust Outlook/Exchange as permanent file storage.

Now with "New" Outlook you don't even get that, you get an ODT cache file, everything else is permanently server side in Microsoft land.

Enterprise "productivity" software is fundamentally broken.
