#54 Exchange 2010 EWS Connection Not Working

[Ben Franske]

Hello, I am trying to use DavMail 3.8.0b1-1273 with our (recently upgraded) Exchange 2007 server. The only place I saw that should be set differently for EWS support is using /owa/ instead of /exchange/ which I have done. I thought it was working for a minute but now my log is filling with errors like:

and I am not able to connect. Any suggestions/new builds would be appreciated as I really miss having DavMail access to the server, I can't stand OWA! Thanks for the great software which worked like a charm with our old Exchange 2003 infrastructure.

I have attached a copy of my davmail.log file with passwords and encrypted strings removed.

To enable experimental EWS support, set the hidden davmail.enableEws property to true in davmail.properties

[Ben Franske]

I have set the property as you indicated and it seems to be attempting an EWS connection now but is still unsuccessful.

I get a:

Though I can clearly reach the host as it detects a script based logon and follows several redirects.

Any assistance is appreciated!

[Mickael Guessant]

Are you able to access Exchange Web Service endpoint at:
/ews/services.wsdl
?

[Ben Franske]

No, I receive a 404 error when I try to visit /owa/ews/services.wsdl I CAN hit /ews/services.wsdl without the /owa/ and I CAN also hit the older style EWS at /owa/ews/exchange.asmx

[Mickael Guessant]

Please update to 3.8.0b2 or latest trunk if you have an Exchange 2010 server and add davmail.enableEws=true in davmail.properties

[Ben Franske]

I am using 3.8.0b1-1291 with enable.Ews and am still having the problem:

Thanks!

[Ben Franske]

Sorry, in my last message I meant I was using 3.8.0b2-1291. Still the same problem.

[Mickael Guessant]

Then you can either have a look at trunk 1323 that is working with a test Exchange 2010 server or send a log file to mguessan@free.fr or both.

[Ben Franske]

I just downloaded and built trunk. Still having problems but the error has changed to "EWS end point not available". I think it is a problem with the URL that DavMail is trying to hit. See my previous message...

I receive a 404 error when I try to visit /owa/ews/services.wsdl I CAN
hit /ews/services.wsdl without the /owa/ and I CAN also hit the older style
EWS at /owa/ews/exchange.asmx

I have also attached to this bug a copy of my current (trunk) generated log file (cleaned of passwords).

Thanks!

[Ben Franske]

DavMail log file (running trunk 2010-07-02)

[Mickael Guessant]

According to the new log file, this is an authentication issue.
Form Based Authentication against OWA is successfull, but access to EWS endpoint at /ews/exchange.asmx is denied (403)

Do you use your email address or username to logon ?

[Ben Franske]

I normally use my username in domain\username format. I have tried all possibilites though (username alone without domain, email address, etc.) with the same result.

My reading of the log file is that DavMail is attempting to connect to /ews/exchange.asmx which does not exist on my server (403) per my previous message. I have the same problem if I try to visit this URL in a web browser (403 error).

I think I need to get DavMail to access either /owa/ews/exchange.asmx (for the older style interface) or /ews/services.wsdl (for the newer style interface). I can successfully access both of these URLs from a web browser.

Is it possible for you to add another hidden property so I can specify the full path for the exchange.asmx or services.wsdl? I think this may fix the problem.

Thanks!

[Mickael Guessant]

I would say your Exchange admins just disabled EWS access to your server: AFAIK, there is no /owa/ews path on any Exchange server, /ews is the root since the first release of EWS on Exchange 2007

[Anonymous]

I would like to try out EWS, but can't get it to work either. It does connect to the server and seem to find login forms and other stuff, then it fails the username/password combo, no matter what I try.

If I login to the webmail, I use only username+password with no domain, but otherwise the domain should be "office", though it used to be "NET", so I tried that as well. I'm attaching a log of my own, so you can see the redirects and so on that DavMail does.

Should there by another url or something, I'm using the "/owa" one now?

It's exchange 2010, company just upgraded and I'm missing my thunderbird! :)

Thank you,

/ Kristoffer

Ummm can't seem to find a way to attach file, but it's all variations on the below, except that it doesn't suggest I add domain\ when I try with domains. :)

To Stoffe: reason=2 definitely means authentication failed.
For Exchange 2010, pleas make sure you use latest trunk revision (3.8.0b2 does not work)

[Anonymous]

Ok, thanks!

Trunk works to authenticate, but only... seems to keep one message in each folder. No real error messages. But guess it's getting there? Calendar does not work but gives a million error popups that I can't read. :)

Keep it up, hope to get this workig soon... :)
