MS Exchange server for tasks and calendar, OneNote for notes, SharePoint to sync these notes.

Closed source, expensive, designed to be supported by professionals, you might need more than 1 server/VM to run them all, requires AMD64 processors.

Well tested (used by millions of people every day), relatively secure, not terribly hard to setup (follow installation guide / best practices documents carefully, and you should be fine).

OneNote is worth it by itself, it's so good. It also works on mobile really well, the search is awesome,I just wish the sync was slightly less opaque for large notebooks with multiple authors.

OneNote would appeal to me if it had the sort of "go find all my todos across this notebook" feature that OrgMode provides via the org-agenda.

AS is, I've never found it super useful. j

Viewing tagged notes has been in OneNote since 2010, not sure what you mean. ToDos are a built-in tag type, but you can also create arbitrary other ones and filter based off of those.

I mean individual items within a note, not entire notes.

I'd want to a collated set of all the items marked as "to do", ideally with due dates, in a "virtual" page or view of the data.

I understood you, that's what this does. See the quote below extracted from the link I previously posted. Note that the page it autogenerates is post-filtering and works the same way for any tag (built-in or user created). The summary screen is usually enough for me, but the full note page is nice sometimes because you can annotate it just like any other page.

"If you want to view the tag search results as a notes page, click the Create Summary Page button at the bottom of the Tags Summary task pan."

Huh, interesting. Doesn't seem to be an option on the Mac version, and I don't think there was this option the last time I tried to do it in Windows, but I'll admit that was a while ago.

love OneNote, easy and quick for collaborative documentation around implemented systems. It does seem to process the text from images so it can search on them. However, searching IP addresses is not very good

Actually my business email is currently setup like this. I have a business o365 account and use Outlook on Windows/MacOS/android/iphone and Thunderbird on Linux.

But I want to move away from it because I want to 1) gain control over my data and 2) extend the system with automations.

Thats why I started researching open source and self hosted alternatives.

You can run all of the above on your own server[s]. Gonna be expensive though, e.g. $500 just for the OS.
