How to create item in a shared calendar use java - calendar

Seems EWS(Exchange Web Service) don't have this feature, does anyone know how to access or create an item in a shared calendar.

EWS does allow for delegate access. https://msdn.microsoft.com/EN-US/library/office/dn641956(v=exchg.150).aspx.

How do you get a URL to a shared O365 calendar?

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

"Out of office" Calendar in Office 365/Outlook

All,
I was wondering if there is any way that you know of to automatically populate a Calendar in Office 365/Outlook based on what other users enter to their calendar.
The HR manager wants to have a calendar that shows when employees are out of office all in one place. Having a shared out of office calendar people can "invite" makes sense, however he believes people will forget to do this and it wouldn't be effective!
I've so far found no obvious way of doing this.
Thanks in advance.
The closest built-in feature to a global or master calendar is not a single calendar, but the ability to overlay multiple calendars in Outlook's Calendar module. External calendars would of course have to be shared/delegated to you first, but you would at least have a central point to view appointments from multiple people using this method.
However, if you prefer a single Calendar but need appointments from other Calendars in it, then you're definitely looking at synchronization - but you can't synchronize multiple calendars in Outlook natively. For that you'll need to look at a custom solution (such as an add-in) or third-party tools:
http://www.slipstick.com/outlook/sharing/more-tools-and-utilities-for-sharing-data/
You could develop an app or a service that uses Outlook Calendar REST API.
Your service would poll the employees calendars, compare their status with a local database and create new events on your shared calendar using again the Outlook API.

exchange web services with calendar appointments

I'm trying to use exchange web services impersonation to add appointments into calendars. I am using Exchange Web Service Manager API and it worked fine when I tested with one account. Since my application will have to do this operation with about 20 000 accounts I am wondering what is the most efficient way to do it? (if it's possible)
Thanks in advance.
Only option you have is to call CreateAppointment in loop. Each iteration has to have the appropriate user impersonation before creating the appointment using Appointment class

How do I create an Outlook calendar subscription from my web/app server?

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:

Authenticate and GetRoles of ActiveDirectory users in a disconnected WPF application via MembershipProvider

I have a project requirement where I need to authenticate against ActiveDirectory in a remote/disconnected WPF application.
There is probably several ways to attempt to do this, but what would be the best approach using ActiveDirectory's MembershipProvider?
I need to:
Authenticate that the user exists.
obtain the AD user's groups and roles.
This needs to happen from a remote location, outside of the network Active Directory resides on.
From within a WinForms or WPF application you can now take advantage of "Client Application Services" (thanks MS for a very generic name, searching for help is now very painful!).
This allows you to connect to a WCF service that can validate the logins. The link above has a walkthrough that shows how easy it is to get it all working, once you have a working app you can modify your config to point to a different MembershipProvider and/or RoleProvider.
It's worth noting that the out-of-the-box solution includes a MembershipProvider named ActiveDirectoryMembershipProvider, but there's no RoleProvider for Active Directory.
If you do require the ability to get Roles (or Groups) and you are working with .NET 4.0 then you can take advantage of the new Active Directory API added that makes everything much easier, namely System.DirectoryServices.AccountManagement. For the most basic of Membership and Role services you'll want to have the following to create your own basic MembershipProvider and RoleProvider:
MembershipProvider.ValidateUser() - should use PrincipalContext.ValidateCredentials()
RoleProvider.GetAllRoles() - use a new GroupPrincipal() as a source to a new PrincipalSearcher()
RoleProvider.IsUserInrole() - use UserPrincipal.FindByIdentity() method to get a user, use GroupPrincipal.FindByIdentity() to get the group, then use the IsMemberOf() method on the user to see if they're a member of the group.
You can implement as little or as much of the API as needed, you should find everything you need in the new AccountManagement namespace to do this.
