Hello! My name is*****I am a certified computer professional who will assist you.
Please tell me if you usually access your GMail account using a web browser (web mail interface), or you use a desktop e-mail program such as Microsoft Outlook?Let me know,IT Miro
OK. Did you send the same e-mail to multiple recipients today?
Sending to 20 recipients at a time shouldn't be a problem. Please attempt to send a new e-mail and let me know the exact error message or code you see. For testing purposes, you can send a new e-mail to yourself.
Please try to send a new e-mail using both GMail web interface and Outlook. Let me know the results.
Outlook should display an error code other than just saying "error".
Since there could be several possible causes of the problem, I suggest we establish a secure remote session so that I can see the problem myself and help you directly.Let me if you would like that.Thanks,IT Miro
I am out of further ideas, so I will opt-out and allow other Experts to take a look at this problem.You will be notified when you receive a response.Regards,IT Miro
