Migration from Google to different platforms using On Demand Migration for Email (ODME) results in multiple warnings regarding the connection to the source.
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond (Tried to read a line. Only '' received. Please make sure that antivirus and firewall software are disabled or configured correctly."
Once the connection to Google is broken, ODME will restore it and continue with the migration process.
Warning does not mean that the Migration process failed.
