I cannot configure Zimbra 7.2.2 (Mac) to connect to an Office365 mail server. I'm asking for your help.
I've searched Google and the forums, but I cannot find help for the topic.
I tried connecting with Microsoft Exchange IMAP and then IMAP.
I tried various port numbers (443, 993, 587) for the incoming and outgoing server.
I tried all security options (SSL, TLS).
I tried working with SMTP authentication.
I compared the settings to Mac Mail (it's working with Office365) and Mac Outlook 2011. Both clients "work" but they have issues.
I'm hoping Zimbra can outperform each in terms of features, functionality, speed and responsiveness.
