I’ve been trying to use the knime email connector (labs) node with not much success. I’m using outlook and tried the following settings in the node with different port numbers email server: outlook.office365.com port: I’ve tried 993, 995, 110 but none seem to work When I try 993 with my credentials it mentions “Execute failed: AUTHENTICATE failed.”; but I use that username and password to login for mail. When I use 995 / 110 / 587, I get the following error message Execute failed: Couldn’t connect to host, port: outlook.office365.com , (Port Number); timeout -1 → I’m assuming these may not be the right port numbers. I’m trying to access a mailbox to read the body of different messages and convert them into a table. I would appreciate your advise on the matter; is it possibly an IT restriction that limits the connection?

Hello @Sajith , I used the following settings to connect to my personal email account: [image] Make sure to replace with your email address e.g. firstname.lastname@outlook.com If you use 2-factor authentication you need to create an App password as described here: Using app passwords with apps that don't support two-step verification - Microsoft Support Bye Tobias
