I have not been able to send emails with Outlook 2016 since 23 December. And for some time before that it would not send emails with attachments. I have run a full suit of a/v and malware scans with Kaspersky, mbam, Superantispyware, adw cleaner, JRT and Hitman Pro, and the machine comes up clean. I have tried uninstalling and reinstalling Office, all to no avail. I have a gmail account so have been able to send with that, but want full use of Outlook, that email address is important as contact for a number of apps I have installed. Ideas welcome.
