Does anyone know of a way to use something like Google Calendar to subscribe to multiple ICS calendar feeds so that I can create a new calendar with the ability to grab it's ICS feed so that all the events in Calendar A and Calendar B (as supplied via ICS feeds into the new Google Calendar) will appear together?
I need the new calendar to poll the feeding ICS files and not do a hard single import function.
E.g. I want a way of creating a new MASTER calendar which is feed by multiple existing ones via ICS feeds.
I managed to add multiple ICSs by following this method:
I sent an email to my gmail account and included in it a bunch of ICS files as attachments.
I opened the email inside gmail and hit an option of adding to calendar.
All done!

I have been playing around with the Graph API to access the shared calendars and events within an organization.
I can successfully query my organization users and the calendar/events for any of those users. What I would like to do now is to generate a URL allowing you to jump to an outlook web session (eg - https://outlook.office365.com/calendar/) directly to a particular user's calendar (that you have access to).
I can see that Events have a 'WebLink' property that allows you to do this with a calendar event, but I can't find any documentation that indicates how you could jump to a calendar the same way.
I did find some old stuff implying that the old school OWA used to allow this but those url's don't look like they work anymore.
I also tried to pull apart the URL's provided when you 'share' you calendar with an external email address and it sends them a 'click here to add the calendar, or here to see a web view' etc email. That looked kind of promising because it actually DOES provide a direct link to a web version of the calendar; but it it includes a few fields in the URLthat I can't figure out (more than likely the external user auth) so I can't reverse engineer it to build one with the info I have available in the Graph API.
URL was of the form:
https://outlook.office365.com/owa/calendar/<userid>#<domain>/<52CharacterHex_ProbablyAHashedTokenForTheExternalUsersAuth>/<WindowsUserSID_ProbablyToRepresentTheExternalUserOrProxyAccessEntity>/reachcalendar.html
Anyone else got any ideas on how I can launch a web session of another uses calendar (that I have access to)? Ultimately what I am doing is creating a small management dashboard (using a summary built via Graph API data) that shows an overview of a collection of user's calendars but allows you to jump into the any individual user's full calendar if more info is required.
Publish to the web. follow this:
https://support.microsoft.com/en-us/office/share-your-calendar-in-outlook-on-the-web-7ecef8ae-139c-40d9-bae2-a23977ee58d5
basically
OWA -> Settings
Calendar -> Shared Calendars
Publish a Calendar -> copy HTML
If I publish a .ics file for purposes of being subscribed to by a calendar application (Google, Outlook, etc), do I have to keep events that have passed? Or can I only include upcoming events?
The ICS file doesn't require old events be kept. If you delete old events from the ICS file, they would cease to exist in the user's calendar, since the ICS file is distinctly separate from the recipients calendar. Most users would probably be comfortable displaying events only going forward.
I am generating ics/iCal files for events in a Web app and emailing them to users to add to their calendars. This part works great
I would like to require a response in the ics files and then capture their responses. I was under the impression I can specify a URL to my Web app in the ics file. Then I can parse the email and attendee status from the response format.
Is something like this possible? I can't find any ics documentation to handle something like this.
Thanks!
Unfortunately, this is not possible. It's possible to specify in an iCalendar object that a user should respond, (by using the relevant parameters in the ATTENDEE property), but the result will be sent back as an e-mail response.
unless the receiving user runs a caldav server with scheduling support.
Is there a way to send mass email and automatically add a calendar reminder the users' calendars? I've found you can export an .ics file and link to that where users can import into their program of choice, but what about something that will do it automatically to any calendar? I've used this article to follow, but nothing for automatically adding to the user's calendar nor do we use that email service.

You can not force someone to automatically download the .ics, as you can imagine, auto downloading anything in email would pose a security risk to the reader.
All you can do is host the .ics (or any file really) on the web and hyperlink to it with a 'Save to Calendar' type linkin your email.
I believe there is no way to do this automatically. One of the important reason is JavaScript is not allowed by most of the email client.
I think the best way to show user a event and make it easy to add to their calendar is generate a .ics file and attach to the email as an attachment. Many email client, like Gmail, will find it and display it as a part of the email.
Here is a reference of .ics file format http://en.wikipedia.org/wiki/ICalendar
I have a website that is a calendar with all the basic features (ASP.NET MVC and SQL Server). People can enter events, view others events, etc. One person asked me if there was a way they can see these events in their Outlook calendar - as a second calendar.
I have all of the data on the server. Is there a recommended way to have Outlook point to my web server or DB for a calendar? I see there are ways to generate iCal files from C#.
If so, how would this data stay in sync as new events are created, deleted, etc? A one time dump would be ok but the concern would be that the data would get stale. Is there a solution that would keep the reference dynamic to keep them in sync. (it would only need to be a one way transfer, i don't expect the need to create or delete from Outlook, so outlook is just read only)
I think you can create iCalendar file,then publish it ,so let clients subscribe your internet calendar because internet calendar subscription is periodically synchronized with a calendar that is saved on a web server,and any updates to the internet calendar are downloaded automatically into MS Outlook.
You can use DDay.Ical library for creating (.ics) files using C#.
assuming your question is about how to keep the client and server side synched, and since you only mention outlook as client, there is a custom way to control the update frequency: microsoft has a custom calendar property: X-PUBLISHED-TTL (see microsoft msdn calendar)
2.1.3.1.1.15 Property: X-PUBLISHED-TTL
Brief Description: Specifies a suggested iCalendar file download frequency for clients and servers with sync capabilities.
however note that this property being custom will be ignored by other calendars
You could try to keep track of the SEQUENCE of updates to each calendar entry in your database, and add a trigger on your table of calendar events so that it would automatically send event updates when something changes. Each update would have a higher SEQUENCE property than the updates that came before it, but the UID (the event's unique identifier) would remain the same.
For this to work, though, you'd need to be able to send iCalendar events from within your SQL Server, which can be possible using the following CLR project:
