Grant access to all users calendars

Copyed this awnser from an other post (https://www.experts-exchange.com/questions/23586579/Exchange-Calendar-Permissions.html)

Hi there,

Came across this when looking for something else.I use a utility called PFDAVAdmin.exe.  It's a microsoft utility to do just what you require.  It's free which is nice.  I use it to set review permissions on everyone's calendar in the whole organisation.  You can also use it to set an individual permissions as well.  It can also do other folders within the exchange mailbox and works with Exchange 2007.

I followed the following articles, and it worked for me.

And here is the download from Microsoft:

I remember it being a little bit tricky to set up - I couldn't install it on my exchange server, and the server or workstation you intstall it on requires (I think from memory) the exchange 2007 management tools

Good luck.

Let me know how you go...

Hi,

PFDAVAdmin.exe will only run with Exchange 2003 and 2007, but I found this tool named ExFolders, http://blogs.technet.com/b/exchange/archive/2009/12/04/3408943.aspx. However I've copied the ExFolders.exe to the server's Exchange \bin folder but ther application crashes.

Can anyone help me?

After adding the required information to the registry I can now run exfolders. I'll look at it and get back.

I've selcted a mailbox on the ledt side and use Tools\Set Calendar Permissions to grant myself Reviewer permission but I still can't open the users calendar. Does anybody have an idea why?

Thanks,
Ronnie

Powershell was the easiest solution.
