Hello, how is it possible to connect ispconfig to office 365 via a "connector". I have mailboxes on the Office 365 server and on the ispconfig server with the same domain. I was able to configure Office 365 and Office 365 also forwards the mails to ispconfig, but it doesn't work in the other direction. The mails are delivered locally. If adjust "Disable (local) delivering" then no more mails are delivered at all. Many thanks in advance. Chris
Maybe try adding a transport entry under Email Routing for each email address you want to live in Office 365. In general splitting an email domain so a partial set of accounts exists in completely different mail services is problematic for both incoming and outgoing/local mail. If you figure out how to make it work acceptably, you might even leave a note here in case another Office 365 user comes across this.
