Calendar sharing - Office365 - External users
-
We have an Office 365 exchange environment. I would like to create a resource (conference room) which has a calendar. That calendar should be able to be edited by internal people, but needs to ALSO be shared to external (non 365 accounts/email addresses). These external accounts should be able to see and add to the calendar.
Is this possible ? If so, what is the procedure? I'm finding a lot of documentation on it, but so far, I can not seem to get the sharing/permissions correct.
-
Do you have the Calendar Sharing for external users enabled? My organization has that turned off, so we can't share calendars externally.
-
@dafyre I do have that enabled, and I can see the calendar via a URL now, which is a great step. Now I just need external people to be able to edit it.

@AdamF : Clear instructions here but take note of their caveat. Only Outlook users will be able to edit the calendar. Users using other clients will NOT have this ability.
I saw that article. The caveat is a deal breaker unfortunately. This seem so overly complex for such a simple requirement. I guess I could just use a google calendar instead.

Can you edit a google calendar from within Outlook? or using iCal on an iphone? I mean maybe you can...

@AdamF Yeah, External organization Calendar Editing has always been an issue with Microsoft Exchange and Office 365.

Yeah that is a real shame. And such a simple thing to do! Oh well.
-
I think the bigger issue here is you'd have to validate who is editing the calendar from outside of your org. Which means you'd have to grant those people access to the calendar and have them authenticate.
I'd look at using FindTime from microsoft if I needed this. There are a few other tools that work too, I'm drawing a blank but I think it was something like Calendly that I had used in the past that would offer time slots to book events on people's calendars, rooms could auto accept so long as they have at least an E3 license IIRC.

What do you mean simple?
I mean yeah, sure you can do this with a google calendar, as long as everyone involved has a google account - but I don't know if you could only do that in the Google mobile app, or the web interface ... what I don't know - assuming the corp account allows it can anyone be granted edit rights with a MSA?

These external accounts should be able to see and add to the calendar.
how do you authenticate something "external" to O365? External is a reference to something not authenticated, in this context.

In this case, it is just a shared calendar for a conference room. (who booked the conference room) So even if I had a public link, which requires no authentication, that would be fine. I'd just give the URL to the 2 people who need it and be done with it. The catch is, the link has to allow editing.

You can't edit without authentication. No system that I know of allows that, you'd likely end up with all kinds of craziness.

Look at Microsoft FindTime to do what you're wanting.

You missed his seemingly ridiculous requirement that they be able to edit the calendar in whatever app those external people are using for calendars already.

No I saw it, just ignored the point as it's not possible. He'd knowingly be accepting all kinds of risk into his org.
Can't do it, period. This at least allows the participants to vote for a time slot (nearest to editing) an event by having an authenticated link to find available time slots.

I've had to do this for outside entities... in our case we ended up buying more licenses for those personal, creating accounts for them, and they use webmail - done. Those external users have to look at two different systems - it's just the way it works.
Again, only way I could see a single app solution work is if all parties involved used the same platform and the app supporting it allowed multiple simultaneous logons to open multiple accounts OR the first account logged in is able to be granted rights on the additional accounts. But this is like the third time I've said this

So Free/Busy would work on a federated level and you can actually use the schedule assistant from another Office 365 account to see that however that is all you will get. That said the user will need to send an invite regardless. There is a Uservoice on this
https://office365.uservoice.com/forums/273493-office-365-admin/suggestions/36486493-allow-calendar-updates-for-external-usersThere are other options like setting up a calendar in Sharepoint and external users can do that.
