Understanding Outlook Free/Busy Permissions

AntExpert

There are various permissions levels to choose from when sharing an Outlook calendar. If a user wishes to share their free/busy status (which is the default user policy on Exchange I believe), should this information only be viewable in the scheduling assistant or should the user have the ability to open the shared calendar?  Even if I add the "folder visible" permission, the user still cannot open my calendar.
Is this by design does anyone know?

You should be able to open the calendar in the calendar view as shared calendar. You will only be able to see the free busy time without any details.

Ability to see free busy allows you to schedule and view their calendars as such. There is an option to also configure how many months free busy people can see.

Ok, there must be something wrong on the Exchange server then. Users receive the error message "you do not have permission to view this calendar", some receive that error when trying to open the email invite.
The permission "full details" works and I noticed "Free/Busy Time, Subject, Location" works only when viewed in the scheduling assistant?

What version outlook clients are they using? I recall this an issue with outlook for Mac 2011.

This should work for outlook 2010 and. 2013. Try running ms office and windows updates on said clients. Check for updates on the server side as well.

What version of exchange are you running ?
This is a known in issue in 2007, not sure if this applies to you.

Recently migrated to Exchange 2010 Standard. Seems to happen on all versions of clients, Outlook 2007 and 2013 as well. Trying to narrow it down. Things seem to be pretty normal with the exception of granting the "Free/Busy time"  and "View Folder" permissions. You can view this information in the scheduling assistant, but users cannot open the calendar directly.

Can you take a screenshot of the room or user in question? Is the everyone assigned free busy time as default?

Happens on all users that I have tested.

Ok - it sounds like there might a config issue on the server side.
Some of the settings I would check include Autodiscover settings and Certs.

Here is a guide on how to do so.

After further testing, it appears the problem is between Outlook 2007 and 2013. Outlook 2013 calendar permissions work as expected. I will do some more testing and post my findings.

Thank you for your help.

It appears that an Outlook 2007 user must allow full details in order for an Outlook 2013 user to open their calendar. Everything seems to work as expected except for the mixed client scenarios.

After testing with different Outlook versions, I determined that a problem only exists when sharing calendars between unlike versions, in certain situations.
