We have on-premise exchange 2013 SP1. We have a number of franchises that we would like to share a calendar with. So these users would be on the internet and we want them to access a shared calendar of ours (they do not have exchange or office 365). According to:

https://technet.microsoft.com/en-us/library/dd638083%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396

we need a sharing policy. However, when i follow:

https://technet.microsoft.com/en-us/library/jj657494(v=exchg.150).aspx

the only option is to enable a federated trust. There isn't an "individual" option under organization->sharing. How do you create a sharing policy in exchange 2013?

OK, so that article is a little misleading or i still am not doing this right. I created a "test" calendar on my mailbox and sent an invite to my personal email account. 2 things:

- the invite does not contain https as the link. It only has http so users will have add the "s". How do i correct that?

- users are not able to create/modify anything on the calendar. How do i give external users the ability to modify/creat content on the calendar?

Hi,

According to your situation, I suggest to Enable Internet calendar publishing. This feature allow users in Exchange 2013 can share calendar availability (free/busy) information with users in non-Exchange organizations and other individuals with Internet access. Please take the following steps to configure this setting:

1.    Configure the Web proxy URL

Set-ExchangeServer -Identity "Mailbox Server" -InternetWebProxy "<Webproxy URL>"

2.    Enable the publishing virtual directory

Set-OwaVirtualDirectory -Identity "CAS" -ExternalUrl "<URL for CAS>" -CalendarEnabled $true

3.    Create a sharing policy specifically for internet calendar publishing

New-SharingPolicy -Name "Internet" -Domains 'Anonymous:CalendarSharingFreeBusySimple' -Enabled $true

The following sharing policy action values can be used:

• CalendarSharingFreeBusySimple:   Share free/busy hours only
• CalendarSharingFreeBusyDetail:   Share free/busy hours, subject, and location
• CalendarSharingFreeBusyReviewer:   Share free/busy hours, subject, location, and the body of the message or calendar item
• ContactsSharing:   Share contacts only

Best Regards.

Will the internet users have "read, write, edit and modify" access to the calendar using the above steps?
