When I attempt to send a message, it immediately ends up in LOCAL OUTBOX. No ERROR message. I updated to latest version 10.0.3530 no help. When I close program, it prompts me to SEND MESSAGES AND CLOSE. Clicking on it results in SEND FAILED “Send operation failed with errors. Do you want to close the application anyway?” I am running eM Client on mine and wife’s PCs with OUTLOOK accounts, mine works, hers fails. Not sure when problem started, maybe 1 week or so ago. I can send emails from her outlook on the web.
Problem cleared this morning on it’s own. Maybe was an Outlook email server problem. Will probably not ever know why…
