If neither of those work:
1) type command prompt into the Windows start menu and open it
2) type:
ping imap-mail.outlook.com
and press <enter>
You should see something like this:
Code: Select all
C:\Users\username>ping imap-mail.outlook.com
Pinging imap.glbdns2.microsoft.com [207.46.11.202] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 207.46.11.202:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
"Pinging imap.glbdns2.microsoft.com [207.46.11.202] with 32 bytes of data"
which tells us -- in this example -- that we were able to resolve imap-mail.outlook.com to an IP address (207.46.11.202), and thus, it's not an "unknown host". (The "request timed out" is irrelevant in this case, some servers don't respond to ping requests). You don't need to copy/paste the result (it's a little tricky in command prompts), so just let us know if yours looks similar to this (you may get a different IP address).
