how to prevent users from seeing Calendar details
I would like to prevent users from seeing Calendar details of other users.
For instance, if I open an new appointment and add attendees, I will be able to see their calendar details.. All I need to show up is Free/Busy.
In Exchange Sharing Policy it setup to Free/busy Only...but I still can see calendar details of other people.
any help will be very much appreciated.
Thank you

The answer somewhat depends on what steps you are taking to be able to see their details and exactly what details are you talking about? What version of Outlook/Exchange are you using?

We use Exchange 2010 and Outlook 2010.
for instance , you create new appointment and when you add an attendee , you will see for instance tuesday 10am to 11am that he is having Lunch with his wife....etc...
it should only show Busy or Free...
I checked Exchange server sharing policy, and it is set up for Free/Busy...
For instance:
In my Outlook Calendar permissions , the "Default" user permissions is set to Reviewer, even if I change it manually to Free/Busy time, the next day I will go back and see it changed back to Reviewer...

I would dig into some AD or Group Policy settings gone wrong to solve that one. If you change it and it changes back say after a log on or reboot or just after 90 minutes. I will try to find something if I can.
This article is written for Exchange 2003 but the AD/GPO stuff is probably still similar. At least it may point you to where the controls are in the GPO.

in the link above it was about publishing free/busy information…
in our environment case, it is like the permissions for the DEFAULT user reverts back to reviewer from free/busy .
I believe since Exchange sharing policy is set up to Free/busy only should apply …
I will need to run Gpresults on my computer and hopefully I will find which GPOs are applied to my account

On this link, that 's what they say when you scroll down to the conclusion, when the policy is set up that way, which is the same as in our environment, then the Default user in Outlook calendar will have Reviewer permissions….even though in sharing policy is set up to free/busy only..

As you noticed, in Mailbox tab of the screenshot I pasted, there is no mailbox selected. I wonder if this will apply to every one in the domain since there is an asterisk in the other tab, as Spiceworks link described it.

Though this link says, the sharing policy is only applied with external federated organization.
We do not have any external federated organization in our case.

My Guessing though is Exchange 2010 makes Outlook Calendar Default user permissions set to Reviewer by default…..
that's only my guessing, I hope someone can confirm that with a Microsoft link..
Second Guess, the reason the permissions reverts back the next day, can be due to Exchange cache mode.. I believe the OST file has the previous configuration, so even when I change the permission of the Default user to Free/Busy in outlook (online), next time it synchronizes with the server the OST overwrites whatever was configured online…
I still need an Expert to comment on my Guessing

You can modify the free/busy permissions within the mailbox, to establish the free/busy permissions of a mailbox you would type from the Exchange management Shell.
Get-MailBoxFolderPermissio n -Identity "{mailbox}:\Calendar"
Where {mailbox} is the name of the target mailbox
if the user Default has anything other than "Availability Only" permissions, You can limit the calendar permission back to availability only by running the following from the Exchange management Shell
Set-MailboxFolderPermissio n -Identity "{mailbox}:\Calendar" -User Default -Accessrights AvailabilityOnly
Where {mailbox} is the name of the target mailbox
To do this in bulk, to all mailboxes you would do something like
Get-Mailbox | Set-MailboxFolderPermissio n -User Default -Accessrights AvailabilityOnly
Hope this helps

Either I change the permissions through Powershell or manually on Outlook to anything else other than Reviewer for the Default....The next day , it will revert back to Reviewer.
I check if there is any GPO changing this, but could not find any..
I checked this file:\\Exchangeservername\ c$\Program Files\Microsoft\Exchange Server\V14\Bin\CmdletExten sionAgents \Scripting AgentConfi g.xml
I cannot find anything that is changing the permissions for the Default user back to Reviewer.

Remove the sharing policy, unless your federating with an external domain you don't need it.

<<Remove the sharing policy, unless your federating with an external domain you don't need it. >>
As you can notice on the snapshots above, the sharing policy, is not applied to any mailbox, and even if it was applied, the Action is showing: Calendar sharing with free/busy information only.
