  • I am suddenly unable to send messages using Outlook on my laptop. I am getting the message "Your server does not support the encryption type you have specified. Try changing the encryption method. Contract your mail server administrator or ISP for additional assistance". I have tried changing various settings and I then get the 421 error or the same message as above. Please help. I cannot understand why this should suddenly happen after years of use on my laptop. PS I did contact my ISP and they said it is the mail provider who needs to assist me.

  • I use Microsoft outlook 2010 for my emails, for the last couple of weeks, I have not been able t download my 1and1 email account. I have gone through all the settings and they are as indicated on your help Q & A. Please advise if there is another setting that needs to be altered. Note: The problem seems to have coincided with the windows 10 consolidated update. No other email accounts have been affected, and has occurred on both my desktop and laptop machines
