Did you receive 2FA message？if so, i will add longer timeout.

ghost commented 1 year ago

No 2FA message appeared.

I'm going to try the prerelease at some point today and will see if it works, I think it will need an app password

dinger1986 commented 1 year ago

Enable SMTP Auth use APP password if using MFA https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission#enable-smtp-auth-for-specific-mailboxes

SMTP basic auth is depreciated / about to be depreciated depending on M365 Tenant. OAuth 2.0 token-based authorisation is the updated method.

ie Not all M365 tenants support SMTP Auth.

being able to connect to it using direct send https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365#settings-for-direct-send would fix alot of peoples issues anyways as it should be on a static and the majority of people who set it up will be office 365 admins

williamharwell commented 1 year ago

Direct send requires you to use port 25, which a lot of hosting providers block.

dinger1986 commented 1 year ago

Most hosting providers will remove the block if requested
