Hello everybody

Lastly my e-mail provider (DomainFactory) switched to Microsoft exchange so that I had to adapt all my Mail Programs.

Apparently an update of existing Mail accounts on my devices is not possible so I had to add new accounts.

First problem I have now is that IMAP does not seem to work in Thunderbird. I added a new account with all the necessary settings. But now I always get a message popup that does not even gives me a full description. The text I see is: "User is authenticated but n..."

Then I tried Owl. That now works, but I would rather use just IMAP.


Also another problem. On my IPhone I also added a new account in the standard Apple Mail programm. There it worked. But when I read a Mail on my phone it does not synchronize anymore with Thunderbird. I can see the Mail in the browser version of Outlook. So I wonder why Thunderbird does not synchonize read e-mails that still are on the server....

OWL used EWS, a native Microsoft Exchange format. It is also limited in what it can do in some regards, those limitations are not something anyone but the addon author can help you with.

IMAP is supported by Exchange server, but is disabled by default. Does your hosting provider have an IMAP option that you can enable or are you stuck with exchange protocols only. That is the question you need to resolve and no one here can answer it for you. You hosting service can.
