narinesa 0 Posted July 1, 2018 I have Dahua and Hikvision NVR. Both are on the same network and configured the same and working with gmail. Last week, Hikvision stopped sending email and cannot figure out why. If it relates, the same time paperport scanner software will not start indicating that there is no default email client. But I do have outlook as the default. Paperport is x86 and outlook is x64. Share this post Link to post Share on other sites
