I am received the following message when trying to use the program, “We’re unable to complete your request Microsoft account is experiencing technical problems. Please try again later.”.  But, my account work fine in outlook.com.  It also says, “Password is required for [email protected]”.

On the home page to this forum, look at the message from eM Client regarding this problem.  Click on the message to download a new version that will work.
