Unable to "Try New Outlook" on Windows 10 PC

[#1]

Hello, 

I am running Windows 10 and have Microsoft mail Version 16005.14326.21806.0 running fine with my Plusnet mail account.

However I am now being prompted to "Try New Outlook" when I use Microsoft Mail.  I have tried to setup New Outlook several times now using the IMAP option, but I cannot get it to work.  Has anyone else managed to get New Outlook to work with a Plusnet mail account?

Is there are secret configuration that works?

Please advise.

Don't let OUTLOOK try to set up connection automatically; never works because of PN'S
settings peculiarities. Search this forum for relevant posts on this on how to do manually.

Finally managed to get it working with these settings:

IMAP configurationHostname

imap.plus.net

Port

993

Secure connection type

SSL / TLS (recommended)

SMTP configurationHostname

relay.plus.net

Port

587

Secure connection type

StartTLS

Similar to my settings in MS Office Outlook though I have port 25 for SMTP.

To be a pedant port 25 is for MX to MX message relay. Port 587 is for email client message submission.

Some networks inhibit access to off network port 25 connections, thus a mobile client configured to use port 25 might not work in all situations

@Townman you are correct about port 25, I suspect my configuration is just "historical" and as I never, ever send emails through PlusNet (only receive) it's not been flagged up. 😎
