Since Outlook servers do not support IMAP and SMTP any more, has anybody already tried using DavMail as an Exchange/IMAP+SMTP bridge between Outlook servers and DeltaChat clients?
Here’s the only relevant comment I have found on this forum: Exchange-Support
And here are a few non-DC-specific guides I have found online about MS Exchange with DavMail. The last two are very recent, and also explain how to make sure ALL of you emails are actually downloaded.
