FIX the ablility to overlay an Exchange calendar onto a Sharepoint calendar in Sharepoint Online
When overlaying calendars in SharePoint Online it has a selection in the UI to choose a "SharePoint" or an "Exchange" calendar but the "Exchange" selection doesn't work. There are several posts in Office 365 support that confirms that this feature doesn't work but it still appears in the UI as an option???
I tried created an Exchange calendar overlay on a SharePoint calendar on one of my site collections. However, one of the mandatory fields required is a web service URL. These do not currently exist in SP 2013 Online on Office 365.
We are not considering any improvements to SharePoint calendars for the time being. We recommend using Office 365 Groups with associated Outlook calendars for calendars in a team collaboration context.

Also interested. Would be good to know if this is going to be removed as an option in SharePoint Online or fixed.
Any update? There's been plenty of documentation (see below) in response to your request for more info, Admin.
The problem is the following : https://support.microsoft.com/en-us/help/2997170/-the-http-request-is-unauthorized-error-in-a-sharepoint-online-calendar-after-you-configure-a-calendar-overlay-to-exchange-online
The UI still show the settings to configure this functionality even if it is not supported anymore.
In SahrePoint Online, there is a parameter that does not exist in the on-premise version.
Please fix the ability to use the calendar overlay in a SharePoint Online calendar that is retrieved from Exchange Online isn't supported. Please refer to Article ID: 2997170
I can confirm that this doesn't work and have tried it with multiple tenants (SPO and Ex2013 / SPO and ExO). Please reach out to me if you'd like someone to reproduce the issue with.
I have a SPO Calendar. I select the overlay option for it. I attempt to overlay an Exchange Online calendar with it. It's impossible, and confirmed by MS Support that it doesn't work: https://jamesdiblasi.wordpress.com/2016/02/06/overlay-an-exchange-online-calendar-to-a-sharepoint-online-calendar/

MS Team - please be transparent here. Is this going to be fixed or not? Why have you stated on the support page on my link below that this feature isn't supported? (Last reviewed 20 December 2016). If it isn't supported, why is the option still available in calendar settings? Why have you not come back to all the people on this forum that have been anxiously waiting for a fix?
It is a huge mistake if you've decided not to support this feature.
Microsoft - we need help. Exchange online calendar overlays still cannot be added to sharepoint online. Please, please, please help us. It is now January 2017 and the bug still persists. Help!
Your "experts" can't reproduce the issue? I was able to do so in under a minute.
Requirement: Vacation calendar that can be "invited" to each team members vacation, all team member can see surfaced in SharePoint.
O365 Exchange Group Calendar: https://outlook.office365.com/owa/?path=/group/IS@Company.onmicrosoft.com/calendar
User with Owner permission on both the Exchange Group and SharePoint site, error is:
The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Basic Realm=""'. (0bf5c29d-803f-3000-b301-2c5722c03e55)
Dear experts... try this one to reproduce it.
1) Create a team site and activate the site mailbox
2) Create a new Calendar event
3) Go to the Outlook online calendar and see the event
4) Tell me how to get the exchange based calendar that just got the new event to appear in the SharePoint team site on a SharePoint calendar
One would think that you would achieve that by clicking the overlay link in a calendar and entering something... but no one can figure out what that is without generating an error.
I agree with everything everyone is saying here. This needs to be fixed ASAP. You gave us this feature in SharePoint on premise, only to take it away in Online. Please stop playing with our calendars (and emotions!)
This is an essential part of collaboration in education using ms classroom, groups, exchange and sharepoint. We are considering moving to Google apps unless there is a workaround. Please upgrade the priority. You're making great inroads in the education sphere.

I successfully overlaid Sharepoint calendars on other views before, but today I am told this feature no longer exists. Wow.
Team calendars are so important and it is very helpful to have holidays, meetings, vacations, ... in different colors.

Agree. Now there is no way to overlay an Exchange online calendar to SharePoint online, there is no way to overlay an ics calendar, there is no way to subscribe to a SharePoint calendar except using outlook for desktop (not that useful if one wants the calendar to be synchronized on mobile devices, and it's more absurd that is not possible even on windows 10 mobile devices; And no, the mobile browser view IS NOT a solution).
Currently SharePoint calendars are quite useless.

HEY MICROSOFT, Look at the 26 postings from the PREVIOUS Sites and Collaboration User Voice VERFING THIS ISSUE! If your "experts" are unable to reproduce this issue is says a lot about your "experts"! How about posting a direct phone number to one of your experts so we can call them and explain to a REAL PERSON. Just another MAJOR FAIL with the "New Microsoft"

This is quite a frustrating scenario. We're wanting to overly a user calendar with resources from O365 and SP calendars - this would be a MASSIVE boon for promoting sharepoint and general 365 usage within our organisation.
Currently we would have to look at a 3rd party application which is not ideal, expensive and, frankly, if natively supported would be a huge bonus.

I agree that this is an issue with SharePoint Online. It works in on-premises SharePoint 2013 and Exchange 2013, but it does not work in Office 365. We have opened a case on this issue with O365 support and we were told that engineers were aware of the issue, but did not have a timeline on when or if it might be fixed. I would prefer that the option to overlay an EXO calendar be removed if there is no firm plan to resolve the issue. As it is, we get periodic support calls to explain why users cannot overlay their EXO calendar with their SPO calendar.
the issue stil exists when configured it gives following error:
The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Basic Realm=""'. (0232699d-1046-3000-a479-905f68668169)
Here is company that acually was able to acomplish this, why can't you?
