Server-side sync with Exchange

Howdy!
I know that the user subscription to MS Exchange calendar is covered here: Sync calendar with Exchange unfortunately that requires user participation in the form of actually subscribing to the calendar (and we know users do nothing unless they have to!). Also it is read-only

I am interested in server-side synchronization where all calendars are automatically linked (when Nextcloud is also LDAP connected to the domain and users are based in AD)?

Is this possible?

Nextcloud should be the one and only β€œsave habor” for your data. Synchronizing data with external providers thwarts that attempt. Therefore you can onyl try to use tools like VDirSyncer to get the job done.
