Hello
We are getting "Unspecified error" when querying our DNS server (Query: outlook.live.com) from a PC communication with our DNS We tried to perform the same query from the DNS itself (local host) and we found that the Dig output is showing with the following message "Truncated, retrying in TCP mode". We also observed that the message size of the requested query "outlook.live.com" increased recently from MSG SIZE 221 to 770 Can you please help why we are getting this error (client side) and why the TCP mode is shown in the dig output since other queries do not show TCP mode in their output?
