[Davmail-users] No credentials available for NTLM

[Mike B. <mi...@mb...>]

Moin,

today, to test something, I removed my company mail account, which had 
been working smoothly until recently, and then tried to create a new 
one. Suddenly there is no synchronisation at all.

MailMate 1.14 (5882) + DavMail 5.5.1-3299 on macOS Monterey 12.3

DavMail says:

```

davmail.connection  - CONNECT - 0:0:0:0:0:0:0:1:62298

- DISCONNECT - 0:0:0:0:0:0:0:1:62298
```

The MailMate activity viewer says:

```
12:08:07 Running action
12:08:07 Handling request
12:08:07 Clearing connection to localhost
12:08:07 Ready to run action (type: 1000, retry count: 0)
12:08:07 Clearing connection to localhost
12:08:07 Trying to connect to localhost on port 1025 (CFNetwork) with 
STARTTLS (not required)
12:08:07 Resolved hostname (localhost).
12:08:07 Successful connection.

```

and than nothing happens, apart from a spinning wheel on the account in 
the sidebar. Does anyone have an idea where the problem might be?
