Post a new Event from my web page to Oulook calendar

Sorry, this plugin works in one direction only, reading from a source calendar. I’m not aware of any plugins that do what you’re looking for.

Thanks fort yor feedaback.

I wish could find out a solution for this.

One important consideration is that these programs require a completely different set of permissions to be able to write data than to be able to read it. Being able to write to your Outlook calendar requires access to your Microsoft account. I’m fairly sure Microsoft does offer ways to do this but they generally require the use of an API and are more onerous to set up (and to develop for) than something that just reads a publicly available feed the way ICS Calendar does.

Another consideration is what you intend to do with the events being added to Outlook. Is this just to have them on your personal calendar, or are you sharing that in some way (either a team calendar or republishing out to another place)? Outlook can subscribe to ICS feeds, just like the feeds ICS Calendar reads. So if you want to manage your event data within WordPress but just have a way to also see those events within Outlook, you could use a plugin like The Events Calendar. It generates an ICS feed, which you could then subscribe to from within Outlook.
