We have an Exchange 2007 on SBS 2008 machine. I created 3 resource mailboxes about 2 weeks ago and used PFDAVAdmin tool to assign read-only (reviewer) permissions to the in-built group &quot;Everyone&quot; which worked perfectly.<br />
<br />
Now when I'm trying to Use the tool again I get the following error <br />
<br />
--------------------------<wbr />-<br />
PFDAVAdmin - Folder Permissions<br />
--------------------------<wbr />-<br />
Exception: The remote server returned an error: (401) Unauthorized.<br />
--------------------------<wbr />-<br />
OK &nbsp; <br />
--------------------------<wbr />-<br />
<br />
I'm logged in as a Global Administrator.When I try to connect the tool to the exchange server it is connected correctly and displays all the mailboxes as well. <br />
<br />
The error appears when I right click the Room mailbox which i just created and click on the first option &quot;Folder Permissions&quot;. Please Assist.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Server Software

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
