[Garry Williams]

Login for Exchange server fails with new version (5.3.0 -- just downloaded) of davmail. Works fine with old version (5.2.0).

I just updated to 5.3.0-3065 and am also unable to log into webmail, reverting back to 5.2.0-2961 and I am again able to log in.

[Fulvio Fusco]

Same behavior here. Downgrade to version 5.1.0 (5.2.0 has another problem: Thunderbird requires password at every startup). I'm using imap, smtp, caldav & carddav, EWS protocol.
MS Windows 7 x64 - JRE 1.8.0_221 x64 - Thunderbird 60.8.0

[Ryan]

I was seeing the same thing, went into Settings and set Exchange Protocol: Auto, and it's working now (for me at least).

Thunderbird also now no longer prompts for login on every startup :)

[Garry Williams]

@Ryan: Heh. I don't know what settings you refer to, but the problem comes and goes with only the davmail new release (no settings there).

(If it's important for some reason, I use Kmail as a client [KDE on Fedora 30] connecting to davmail. I haven't modified its settings at all and the bug is only with the new davmail release.)

[rickyrockrat]

I have the same issue. Exchange Protocol: Auto has no effect - it still will not login. Reverting to something previous fixes the issue.

[Mickael Guessant]

Thank you all for your feedback, in order to fix this I would need to know:

mode (Auto/EWS/...)
/OWA or direct EWS (/EWS/Exchange.asmx) path
username: userid ? domain\userid ? email ?

The best would be two WIRE DEBUG log files, one with 5.2.0 and another with 5.3.0 at my private email address mguessan@free.fr

[Steve Turner]

For the record, I upgraded from 5.2.0 to the current tip of master (9f4f822) yesterday. This is one commit ahead of the one tagged as 5.3.0 (1feacf0) and I didn't encounter any issues with authentication. My settings are:

mode: EWS
direct EWS: https://outlook.office365.com/EWS/Exchange.asmx
username: email

[WizGnome]

Mode: EWS
OWA URL /owa/
Username: userid
password 10 characters Upper/lower case, numbers and symbols

[Óscar García]

Looking for differences in my setup. With v5.3.0 it tries to POST to /owa/auth/owaauth.dll even if I have davmail.enableEws=ews in my config file. This POST returns a 404 error:

>> "POST /owa/auth/owaauth.dll HTTP/1.1[\r][\n]"
>> "User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)[\r][\n]"
>> "Host: example.com[\r][\n]"
>> "Cookie: $Version=0; ClientId=R0YZXDSTEKXKSZDXWBAQ; $Path=/[\r][\n]"

>> "username=hidden@example.com"
<< "HTTP/1.1 404 Not Found[\r][\n]"
<< "HTTP/1.1 404 Not Found[\r][\n]"

But with v5.2.0 the POST go to /ews/exchange.asmx and works well:

>> "POST /ews/exchange.asmx HTTP/1.1[\r][\n]"
>> "User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)[\r][\n]"

davmail.enableEws is deprecated, please use:
davmail.mode=EWS
instead, and set url with /ews/exchange.asmx path

[Frieder Schrempf]

mode: EWS
URL: OWA
username: e-mail

[Mickael Guessant]

Ok, found one issue with NTLM authentication
=> fixed in trunk https://github.com/mguessan/davmail#trunk-builds

[Frieder Schrempf]

I just downloaded the trunk build and it seems to fix the issue for me. Authentication works now. I didn't change any settings.

Thanks for the quick fix!

[Óscar García]

I just download the "Platform independent package davmail-5.3.0-trunk.zip" and issue still present.
It always do POST /owa/auth/owaauth.dll with result of 404 error. And davmail.mode=EWS seems don't work.

UPDATE: If I force adding to URL /ews/exchange.asmx seems work well, but in 5.2.0 I don't need to add this endpoint to URL.

[Mickael Guessant]

If it tries /owa/auth/owaauth.dll it means DavMail did not find authentication form at /owa (or any other base path you set). Hard to tell why without a log file.

[Steve Turner]

The davmail-5.3.0-trunk.zip file is dated 6 August 2019 so I guess it hasn't been rebuilt to contain the fix yet.

[Mickael Guessant]

Trunks builds are automatically available thanks to appveyor
=> https://github.com/mguessan/davmail#trunk-builds
contains latest build from last night.

[WizGnome]

Trunk build is failing with Caldav connection. Login to server with username xxxxx failed

Failing Log in Log1.txt Log for working version in Log2.txt

[Mickael Guessant]

Basically form authentication succeeds but EWS authentication fails
=> quick work around is to use direct EWS access (we used to depend on some information from OWA interface but this is no longer the case)
=> if you need to stick to form authentication, I need more info to reproduce your issue: a WIRE debug log of failed authentication

Please don't post it publicly, just send it to my private address mguessan@free.fr

Main issue fixed, please create a new ticket with detailed information if you have a similar issue.
