Sometimes you need to add an entry so that your PC can find a specific DNS entry if your domain's DNS is being hosted somewhere else.
An example would be if you need to add an "autodiscover" entry for Hosted Exchange since your domain is hosted at another provider and they don't update their DNS entries on a regular basis or someone else is using the old entry.
If you have a Hosted Exchange account with InfoQuest and you're doing DNS through another company or you're using the split domain option, you'll probably need to add this entry to your local host file so that your Outlook program can setup your profile using the auto setup option. With 2013 Exchange, you need to have this entry either in your local host file or whomever is doing your DNS to setup up your Hosted Exchange account with an exchange connection.
Here is what you need to do.
1. On your PC, go from the Start button and fine NotePad on your PC.
Once your find it, right click on it and click the "Run As Administrator" option.
2. Then go to the following file: c:\windows\system32\drivers\etc\hosts, then open it.
3. At the top you'll see example, you'll need to add 22.214.171.124 autodiscover.yourdomain.com
NOTE: Where you see "yourdomain.com" that is where you type in your domain name.
Example: Domain is johnsmith.com, you would enter in autodiscover.johnsmith.com.
4. Make sure there is a "tab" space or 3 or 4 space bar hits between the IP address and your autodiscover.yourdomain.com entry.
5. Click on the File, then Save, then close that file.
6. Now Outlook will be able to setup your profile you have with InfoQuest in that program on your PC.
