Mail notification settings

Hi,

I am having problem on mail notification with office365 mailbox.

— WP Mail —

I firstly use WP Mail and cannot receive emails(neither client or admin notification) from the site with office365 mailbox.

Guessing the WP mail is using admin address as sender this may be filter out as spam.

— SMTP mail —

Then i use smtp mail, with correct port and smtp server. Turn out no mail received, even with gmail client.

— Mailbox connectivity test —

I tried to connect to the mailbox via outlook manually with POP3/SMTP.
Find out that Office365 required TLS and SSL connecting to smtp server and I do not see the option there in your plugin

I check with some previous post you have and see that you mentioned another wp_smtp plugin. Is that a testing or that plugin can be used with yours?
