Hi Experts,<br />
<br />
some our customers uses Exchange 2016, Outlook 2016 and a external http proxy Server which is written down in Internet Explorer &quot;proxy settings&quot;.<br />
<br />
If I instruct a user to open a shared calendar from another user a error message appear &quot;... the resource is not available...&quot;. I deactivate the IE proxy setting, map the shared calendar and it function even if proxy settings in IE are re-activated. It's unambiguously a Problem with the proxy settings.<br />
<br />
I tried it with different bypass-lists, unfortunately, without success, i.g. <br />
<br />
netsh winhttp set proxy &quot;external-proxy-fqdn:port&quot;<wbr /> bypass-list=&quot;*.contoso.com<wbr />; 192.168.*; *.local ...&quot;<br />
&nbsp;// (*.local internal AD-FQDN, *.contoso external FQDN, 192.168.* internal IP Range)<br />
<br />
How would the proxy entry have to be built up with it it functions?<br />
<br />
Thx<br />

Hi Experts,

some our customers uses Exchange 2016, Outlook 2016 and a external http proxy Server which is written down in Internet Explorer "proxy settings".

If I instruct a user to open a shared calendar from another user a error message appear "... the resource is not available...". I deactivate the IE proxy setting, map the shared calendar and it function even if proxy settings in IE are re-activated. It's unambiguously a Problem with the proxy settings.

I tried it with different bypass-lists, unfortunately, without success, i.g. 

netsh winhttp set proxy "external-proxy-fqdn:port" bypass-list="*.contoso.com; 192.168.*; *.local ..."
 // (*.local internal AD-FQDN, *.contoso external FQDN, 192.168.* internal IP Range)

How would the proxy entry have to be built up with it it functions?
