What's the solution to this?

I have issue's with the users in my domain basically anyone can access anyones else's calendar (via Outlook 2007), without setting any permissions and we've recently found out that you can even access other peoples folders and mails. This is a big security risk!

How do we stop this?

Software/Hardware used:
Exchange 2010 sp1 , outlook 2007

For Exchange 2010, you can run a PowerShell command to change the default permissions. I run one to set the default permissions for calendars as we want all calenders to viewable to everyone in the company. This is what I run: 3. Set “default” permission to all users calendars to “reviewer: a. $stralias = Get-Mailbox -ResultSize Unlimited -OrganizationalUnit Users b. foreach ($s in $stralias) {Set-MailboxFolderPermission -Identity $s":calendar" -User default -AccessRights Reviewer} Step A sets the variable and step B sets the permissions. The command only sets the calendar, but you can easily change to the inbox by replacing ".calendar" with ".inbox". The variable pulls the users from AD which may need to be modified depending on how your AD is setup.

Does this apply to web access?
