> their focus has been on developing features for business collaboration as opposed to personal & family ones
For people like me, who have to contend with GDPR and NIS 2 requirements on an organizational level in Germany this actually is a god-send. MS and Google don't play nice with the local law, e.g. refusing order processing agreements, although MS has recently started to move on this topic.
We replaced MS stuff (all of Sharepoint, most of PIM) with Nextcloud and MS ADS via SAML without too much of a hassle. The sync client has its nuisances (e.g. can't name Nextcloud instances) and it's getting worse for the last few versions! But it does its job, i.e. syncing, and you can always use the cloud itself.
IMHO, the mail app is very slow and need a large screen. Also it doesn't help to manage emails when you need to delete, to search for something, to put in folders and to deal with spams. But I am a power users who like to keep thing clean. Some employees works with it without complaining. Nextcloud recently "bought" Roundcube and it might become the prefered mail app sooner.
> Do you have one NC instance or do you federate (or plan to) ?
We actually have three instances. Currently they are running side-by-side but federation is planned, I think, starting October. Account management is still done in ADS and will stay there for now. SAML works as intended.
> Do you use the mail app ?
Yes, we use the Nextcloud Mail app without the AI features. Most people are using desktop clients, ie. Outlook, for daily work and it is important to us to keep Nextcloud Mail and Outlook in sync. Since the recent changes by MS new Outlook, it is also on the clock, but we are not there yet.
> Which applications do you use to replace sharepoint features ?
We used Sharepoint for centralized file storage, project management, and department sites and not much else. File storage is a given. For projects we moved to Jira some time ago, so little to do here. For department sites we use the Pico CMS integration.
> Do you use the business version of NC ?
Not yet. We are well below 200 FTE, so too small ;) We are interested, however, in the compliance and GDPR certification and we have already contacted their sales. But I don't know what became of it.
