CalDAV support
Support for internet calendar feeds. The main use case is the ability to see conference schedules in Outlook. For example, I attended WPC and Ignite this year and had to keep switching back and forth between Outlook and the conference website/apps to determine my true schedule.

We need more specific examples of what you’re trying to accomplish from those who have voted for this feature. Are you trying to integrate with a third party application and just need CalDav support? Or are you trying to access your calendar hosted on a different service like iCloud or Yahoo? Please comment with your specific needs.
Thank you for your continued participation in making Outlook for Mac better.

In our company we use a thrid party product for calendars (server), which supports caldav, so most clients can get password protected read/write access to these. Outlook is the only product I currently now, which doesn't support this feature, so we need to run a seperated calendar client and as ics subscription is only for public calendars possible, we can't even sync the events. As there is no plugin for Mac, there is no way to use just Outlook and as of Office 365, this really shouldn't be a thing. Implement it there and caldav is available for every plattform..

Our security team has disabled the native Mac apps for mail and calendar because it doesn't support MFA. I need my personal calendar (CALDAV in iCloud) to show in Outlook (which now is the only way I can see my personal calendar and my work calendar in the same space).

We use confluence to organize data within our group. Within this application we have also created a calendar. Confluence offers integration of these calendars as either calDAV or iCal. As email is still provided with outlook, I would like to link calendars between both applications.

We are in a mixed environment, where we are obliged to use client's or event's contact/calendar shares. Our team uses O365, MS Teams and Outlook for Mac. We have to be able to at least subscribe to Google, Apple and our own company server mail, contact and calendar information.
Often, we have to connect to other Teams channels, Google Docs, Trello and Slack platforms. Most of our team use iCloud.
We try to get everyone to use Outlook on Windows, Mac and iOS. We expect to get the best productivity out of the integration of mails, meetings, contacts and tasks.
One interface in one app, that pulls in all items from the various platforms.
Example:
Someone has a client calendar share on Google. A personal iCloud calendar and contact list. Teams meetings. Exchange. It would then be the best option to show all these different calendars and contact lists side by side in Outlook, without duplicating items across the various servers/platforms.

I would like to have iCloud support.

We use Oracle Beehive as email and calendar server which supports CalDAV, but Outlook for Mac cannot synchronise with it because it doesn't support CalDAV. The standard Apple Mail and Calendar clients don't come close to Outlook and Mozilla Thunderbird/Lightning is only slightly better. Please help!

This one is out of left field but hopefully resolved by CalDAV support as well. I use a combination of G-Suite and O365 accounts for my personal use, but my company uses Beehive for email and calendar. I have managed to get the email working fine, but the Calendar is going to require CalDAV support. It works in Mac Calendar, but not Outlook 2016 for Mac.

I use outlook for work, but me and my family members use various other calendar accounts (some of them CalDAV). I regularly have to attend events in the evening, and it would really help to have all calendars that need to be checked for availability accessible in one place.

We have 2 organizations that share access to a few resources. The resource calendars are made accessible as a published internet calendar from our exchange instances in both orgs.

I'd like to add my iCloud account to Outlook, so that I can see my iCloud calendar appointments/events alongside my Outlook ones. Since I can't, I have to switch back and first between Outlook and Calendar.app to make sure I don't have conflicts during the day between my work/Outlook events, and my personal/iCloud events. (The workaround for me is that I've added my Exchange account as a second account inside the Mac Calendar app; but I still have to switch back and forth to see conflicts, as I prefer to use Outlook for making meetings and checking free time, etc.)

Many sources from other vendors, clients, etc. are CalDav links. It's not a calendar I use in another one of my accounts, but a calendar someone else outside my organization shares (eg a construction timeline). I just want to be able to subscribe and view it alongside my work calendar so I can schedule myself and my staff properly. Currently I do all of that in BusyCal, and just use Outlook as a quick reference.

The scenario: I use Outlook on my work Mac for email & calendaring. I want to be able to add my iCloud account as an additional account in Outlook, so that I can see all my iCloud events in my Outlook calendar alongside my Outlook events. Currently, I have to switch to my personal calendar (Calendar.app) to see if I have any daytime events that conflict, then go back to Outlook to book events. Royal PITA.
My workaround is to add my iCloud account to my work Mac, then add my Outlook/Exchange account into the Mac OS X "Internet accounts" and turn on the calendar, so I can see everything (personal + Outlook events) together in the Mac Calendar.app ... but I really would prefer to see everything in Outlook, since it's better at scheduling and has all my work contacts, and I would prefer to not have my iCloud account connected to my work laptop at the system level. (Just within Outlook would be better.)

I use Outlook on my mac for email. I use Calendar (Apple) on my iPhone and my mac, synchronized via iCloud. What I need to accomplish is to have seamless calendar and Contact synchronization between Outlook and iCloud so that my mac and iPhone have correct, up-to-date information.

I would like to add my Google and Facebook calenders into Outlook, as it was possible with Outlook for Windows

Another easy example is to have proper integration with ownCloud/Nextcloud

What I need is the ability to sync my Google Calendar through Outlook, and see the calendars of colleague using the same G suite account.

Similar to many previous comments pasted here:
1) use Outlook as my single Calendar client on Mac
2) view and edit (including sent meeting invites) calendars in Outlook that are hosted on services such as iCloud and Google. Essentially the same as is possible via the Calendar app on iOS and macOS.
3)I want tone able to access to and modify my personal iCloud calendar within Outlook, in parallel to my professional Exchange calendar.
In brief, Need to be able to see and modify iCloud calendars in Outlook. I use Outlook for work and to have to run another calendar app for personal, and for another start-up. -

Ultimately I need to be able to use Outlook as my single Calendar client on Mac. Currently I can use Outlook as my single email client (O365, Google, iCloud, etc.), but it does not support other calendars.
I have an O365 calendar, Google calendar, and an iCloud calendar. The only place I can see all calendars in a single view is on my phone. This is inefficient. On my Mac I have O365 calendar on Outlook, and Google and iCloud are on Mac calendar app. So when booking a meeting I have to have both Outlook and Mac calendar open to see if I have an open time slot.
I want to use just Outlook and see my O365 along with Google and iCloud. This will allow me to stop using Mac calendar and have a single unified view of schedule.
Thanks

We are using our private CalDAV and CardDAV servers within our company. It is macOS Server, but we want to switch to Cyrus IMAPD. Therefore we need implementation of internet standards RFC 4791 and RFC 6747 and more configuration options to set hostname, port, login credentials for arbitrary CalDAV or CardDAV service (just like with IMAP or SMTP service).
