I've been asked if we can share internally calendar information within the organisation. Is there something I can apply to the "Organization Configuration" to allow this, I taken a brief look at "Sharing Policy" but wasn't sure if I could use this internally as what I've found web appears to point to this is for federation trust... Any help would be great. Thanks Michael

Users can delegate their own calendars to other users if that is what you are asking. http://office.microsoft.com/en-us/outlook-help/allow-someone-else-to-manage-your-mail-and-calendar-HA010075081.aspx Not sure what versions you are using however.

Andy, Thanks, was aware that user could do this and users can ask the other user for access etc, but it been asked if we can give view access to the whole organisation. Thanks Michael.

You can use pfdavadmin,ExFolders or powershell depending on the version of Exchange to set the default pemissions on every calendar. However this is a one-time thing. Anyone who changes the permissions or any new mailboxes will have to be set as well. There is no way to just automatically have the permissions enabled or enforced.

Andy, Don't mind using PowerShell but couldn't work out which cmdlet to use ?!? the enviroment is nearly all Ex2010 and that is what I want to apply the settings too, I have just over 3000 accounts so don't want to get user to set it. Any advice on the PS would be greatful. Cheers Michael.

Sure. 2010 is good! http://technet.microsoft.com/en-us/library/dd298062.aspx Add-MailboxFolderPermission http://technet.microsoft.com/en-us/library/ff522363.aspx Set-MailboxFolderPermission

Andy, Cheers, been playing with these PS Cmdlets and came up with PS-> Add-MailboxFolderPermission -Identity user@domain.com:\calendar -user Default -AccessRights Reviewer Just need to build this into a collection of all mailboxes, and all should be good. Thanks for guidance again Michael.
