Nope, not even in the wayback machine.

Hi all!
FYI, looks like https://outlook.office.com/owa/?path=/calendar/action/compose not working anymore

New Calendar Link https://outlook.office.com/calendar/deeplink/compose

New Mail Link https://outlook.office.com/mail/deeplink/compose

(Still not finding official documentation)

Hi, doesn't seem to work on mobile, opens up the browser but just goes to the Inbox.

Does anyone know if there's a way to construct a deeplink to a specific calendar? Or a resource calendar? Currently you have to select it manually from a dropdown, and the option only appears there if you've selected the calendar in the 'main' OWA view (potentially from one of many hundreds, if you're part of lots of MS Teams)

Does anyone know of any official MS documentation regarding the https://outlook.office.com/mail/deeplink/compose endpoint?

Many sources use "calendar/0/deeplink/compose" but that doesn't work anymore, use "calendar/deeplink/compose" instead and it works!

@robinmalik Did you figure out the answer? I also have such issue

@robinmalik You can deeplink to the view of a calendar -
Mail
https://outlook.office.com/mail/[email protected]/
Calendar
https://outlook.office.com/calendar/[email protected]/view/month

The mail example link should start the query string with ?.
https://outlook.office.com/mail/deeplink/[email protected]&subject=Customer+Service+Request&body=Add+Your+Request+here

Does anybody know a way to define the CC-recipients as well?

Thanks @bodograuman. Updated.

the standard cc=and bcc= that gmail uses don't work, so I'm not sure if they're implemented.

SO on gmail urls https://stackoverflow.com/questions/6548570/url-to-compose-a-message-in-gmail-with-full-gmail-interface-and-specified-to-b

You can deeplink to the view of a calendar - Mail https://outlook.office.com/mail/[email protected]/ Calendar https://outlook.office.com/calendar/[email protected]/view/month

@miwebguy Is there a way to combine this with the "new event" deeplink? I.e. a link that creates an event in a specific calendar?

EDIT: nevermind, got it, it's https://outlook.office.com/calendar/[email protected]/deeplink/compose. The selected calendar says it's still my email address but that appears to be a visual bug, the title bar shows the correct calendar.

Thanks a lot it still works in 2024_08_24. But does anyone know how to use something like BBCode/Hyperlink in Outlook's BodyDeepLink?

For example I want to have hyperlink: https://admin.com clickable when compose mail interface appears...

has anyone find a way to pre-select category or color (url parameter)?

Outlook Calendar Query String Params:
Looking at the script that extracts the Query String parameters from the url and reassigns the values to the form fields the following are available:

Key	Value Type	Notes
subject	string
body	string
startdt	string	ISO string split on (".") removing milliseconds and zulu reference e.g. '2025-01-14T22:43:41.248Z' -> '2025-01-14T22:43:41'
enddt	string	ISO string split on (".") removing milliseconds and zulu reference e.g. '2025-01-14T22:43:41.248Z' -> '2025-01-14T22:43:41'
allday	boolean
location	string
folderid	string
reqresponse	boolean
allowfw	boolean
hideattn	boolean
remindminsbeforestart	number	(minutes before)
freebusy	'free,busy,oof,workingelsewhere,nodata'

Hi everyone. Thanks for sharing this gist. Is there any way to open calendar event creation but with a shared calendar selected by default? I've tried with calendarId, folderid, but nothing works.

Thanks

I just realized that you have to URL encode the folder id.

https://outlook.office.com/calendar/deeplink/compose

@codingwaysarg Did it work to select a shared calendar with folderId? Which ID do i need to take and URL encode?. Help would be MUCH appreciated.
