An Exchange user wanted to know how to share a secondary calendar in an Exchange mailbox.
It's simple: right click on the calendar folder and choose Share > Share Calendar.
This will open a sharing invitation. Depending on the policy settings, you may be able to choose the level of details you are sharing. You will be able to give the person(s) read/write permissions (default is read-only). When you click Send, the calendar will be updated with the necessary permissions.
Calendar Sharing Permission Error
When you share a Calendar in your Exchange mailbox and receive an error message that she can't share the calendar, it's either due to a sharing policy set by your administrator or a problem with your autocomplete cache.
Policy does not allow granting permissions at this level to one or more recipients. Please select another permission level and send the sharing invite again.
If you can share it using Outlook on the web, the policy settings themselves are correct. If you are unable to share it using the permission level you desire, you will need to speak to your Exchange administrator.
If the problem is on the Outlook side (and not a policy issue), delete the autocomplete entry for each recipient then select the recipients from the Global Address List (GAL). The error occurred because the autocomplete entries that came up as you type the recipient's names was their SMTP email addresses, not resolved to their GAL entry, and Outlook thinks they are external addresses and your policy does not allow Calendar shares to be sent to external addresses.
Share Using Outlook on the web
To share a calendar using Outlook on the web, log into Outlook on the web and open the Calendar module. Click on Share in the menu bar then select the Calendar you want to share.
Begin typing in the name of the person you want to share the calendar with. Selecting Search Directory will list people in your Global Address List (GAL) first. Select the person.
Get-MailboxFolderPermission -Identity USER:\Kalender\"Subcalender xyz"
The quotation marks "" helped, before it could't find the subcalender xyz
That is because of the spaces in the folder name.
Hello, when I share the secondary calendar, it's also sharing the details from my main calendar. I cannot find a solution to this. Can you assist? Thank you.
I've found two workarounds. One costs money, the other is free.
For $4/month per person, you can pay for Exchange Online Plan 1. That gives you official Exchange Server features, including a calendar that can be shared among Outlook desktop clients. It works well, but costs at least $8/month for two people.
The other workaround is to create a new Outlook.com account. (They're free, so why not?) Log in to that account in each instance of Outlook and display its main calendar. It's not "sharing" in the usual sense, because you're both/all logged in as the owner of the account, not an owner and subscribers. But it works. (Works with primary calendar only, not secondary calendars.)
plus you can add either business or personal to outlook
...and if you have a domain name, you can get premium outlook.com for up to 5 mailboxes for your domain for $50/yr ($20 first year).
As of mid-September 2017, Microsoft tech support has confirmed that this feature still does not work. My own experience confirms that. I haven't been able to share a calendar for almost two years. I can do nothing but keep waiting for a fix. Or a clever workaround...
Yeah, at this time shared calendar will automatically sync down to outlook desktop but it's still not editable in outlook.
Is this fixed yet? It doesn't appear to be...
I *thought* so, but i could be wrong - i haven't checked it in a while. Will try to check it today.
Sharing Outlook calendars has never worked for me, ever since it added support for Exchange servers (i.e., about 6 months ago). My wife and I want to share a calendar, but the share-ee can't edit calendar items, despite being granted full rights by the share-er. The user who created/owns the calendar has full privileges, while the other person can only view details. Specifically, desktop Outlook complains about insufficient write privileges or the inability to manage a folder. (This is with Office 365 Home on Windows 10.) Any hints?
At this time, Outlook can't edit the shared calendar, but you should be able to in outlook on the web. It's not as convenient as editing in outlook, but at this time, it is the only way that works.
