After installing "Ionics ISAPI Rewrite Filter" version 2.1, and a simple filter setup I have a problem connecting to the exchange and the mailbox. Exchange with IIS 6.0 on Windows SBS 2003 declares the error "HTTP/1.1 503 Service Unavailable". How to set up the exception for directories "Exchange" and "Public" on the Exchange server?

Current settings for iirf.ini:

RewriteEngine ON
RewriteBase    OFF
StatusInquiry ON /iirfStatus

RewriteCond    %{HTTP_URL}    (/|\.html|\.php|\.htm|/[^.]*)$    [I]
RewriteCond     %{REQUEST_FILENAME}    !-d
RewriteCond    %{REQUEST_FILENAME}    !-f
RewriteRule    ^(.*)$    /index.php/$1 [U,L]

#RewriteCond $0 !^/data
#RewriteRule ^.*$ /data$0    [I]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/data/(.*)$ /index.php/sk/images/make_image/$1 [I,L,QSA]
