Office 365 emails not downloading

POP3-SSL should work in this case. Sound like the default IMAP folder doesn’t match what Postie uses. If this is the case you can specify an IMAP folder as described here: https://postieplugin.com/1-8-36-released/

Thank you Wayne. I will try that and see if it works.

I created a new folder within Outlook called “Postie” and then used the rules to move any message to it. The messages are being moved to it but Postie is now saying there is no folder called “Postie” on the server. Do I need to put something else in front of the Postie so it will find the directory/mail box?

What does the debug output look like if you switch to pop-ssl? (remember to remove the folder name)

Hello Wayne,
I was able to talk to Microsoft Support today and asked me to change the domain to outlook.office365.com and now I get the following error. Any ideas on this one?

Now you get to talk with your hosting company to see if they have any restrictions on outbound connections. Basically this error message is saying “I can’t find outlook.office365.com:993”

It seems that Postie is trying to use the mail server on the hosting company to resolve the outlook.office365.com IP address. If I use an IP address, I get error 111 – Connection refused. I had to change the DNS settings on the hosting site so Office 365 would work correctly with our domain.
I don’t think Postie is able to resolve the connection to outlook.office.com after the DNS settings were changed. Any ideas on how to check this?

You would need shell access to your hosting account. Then see https://postieplugin.com/faq/postie-wont-connect-mailserver/

Hello Wayne,
I think I have isolated the problem. Office 365 uses TLS encryption and the only option within Postie is SSL under both pop and imap. Is there a way to add TLS to the encryption type?

Server name: outlook.office365.com
Port: 995
Encryption method: TLS

Server name: outlook.office365.com
Port: 993
Encryption method: TLS

Postie supports TLS as long as your underling PHP supports it.

Note the log you posted earlier confirms Postie is trying to connect with TLS

Socket: tls://outlook.office365.com:993

Note also that the log posted in https://www.ads-software.com/support/topic/office-365-emails-not-downloading/#post-10384813 shows a successful connection.
