OWA add-ins causing problems with WebDav

[Icento]

Dear forum members,

At the moment, I'm experiencing problems with an fresh installation of Enterprise Vault 8.0SP1 - OWA add ins on a Exchange 2007 server.

After setup the web.config file for debug the following issue is seen in the log:

The Exchange server has the CAS and mailbox role installed.

Anyone seen this problem?

Thanks,

Can you describe the issue you are seeing?  Is it with viewing archived items or seeing the buttons?

This line is interesting:

"8-6-2009 20:13:57 [9124,1] [EVContext::LogHiddenSettings] Enabled for archiving: Never Enabled"

 It's timing out getting this this - 8-6-2009 20:13:27 [9124,1] [WebDAVRequest::Send] Request url: https://10.16.176.231/exchange/

Just a question, as that url should also have the SMTP address of the mailbox - did you edit the log file before posting on here?

So it should be for eg. https://10.16.176.231/exchange/john@symantec.com

Can you post what EnterpriseVault lines you have in your web.config please.


Tony, FYI, that line is normal when the OWA extensions can't open the hidden message of the mailbox.

[TonySterling]

Thanks John,  been a while since I have had to mess with owa outside of just running the configuration.  :)

[Icento]

Thanks all for your replies.

I did edit the log to keep out the email adresses listed.

The main problem is that after I ran the setup of the OWA 2007 64bit MSI, Outlook Web Access doesnt work anymore. I takes more than 5 minutes to get an mailbox view and it is impossible to open an archived item. 

I turned on debug logging by editing the web.config file and there it was, a WebDav time out.

Changing some lines like localhost to ip adresses has no effect.

OWA is slow  / not working for everybody, not only the people that has an archived enabled mailbox.

Is there an option to disable the OWA addins by just commenting out the EV program lines?

The Exchange server has some history, it has been upgraded from version 2003.

EV is running fine besides the owa.

IF anyone need some more info or logging, please let me know.

regards,

André Overweel

Have you checked if the WebDAV part is actually enabled, and that the /exchange is really there?

[MichelZ]

Hi

Do you need any more information here?
If not, and you are satisfied with a provided answer, can you choose this as Solution, please?

Thanks & Regards

 Hi,

I'm experiencing same problem on my EV server. Icento, did you find the solution?

Toolbar does not show on OWA 2007, but i can see EV archive icon with archived emails.
When I try to open archived mail I get error message:
"The Archived item is currently unavailable.
If You choose reply, only the content shown will be included.
Click here to preview the Original Item"
When I click new window opens : https://servername - HTTP 403 (Forbidden)

only error i find from log is:

29.7.2009 9:08:44 [6504,6] [WebDAVRequest::Send] Exception sending WebDAV request: System.Net.WebException: The remote server returned an error: (440) Login Timeout.
at System.Net.HttpWebRequest.GetResponse()
at Symantec.EnterpriseVault.Owa.ExchangeStoreAccess.WebDAVRequest.Send()
29.7.2009 9:08:44 [6504,6] [EVContext::LoadHiddenSettings] Exception loading hidden settings:
29.7.2009 9:08:44 [6504,6] [EVContext::LoadHiddenSettings] System.NullReferenceException: Object reference not set to an instance of an object.
at Symantec.EnterpriseVault.Owa.ExchangeStoreAccess.WebDAVHelpers.GetEVHiddenMessageId(Log oLog, EVContext oEVContext)
at Symantec.EnterpriseVault.Owa.Core.EVContext.LoadHiddenSettings(Log oLog, Boolean brefresh)

I get this message from users log when he is logging to OWA.
Also every 5 minutes new log appears e.g. EVOwaLog_CAS_{84a459a876fd4464}@ouraddress.com_20090728_295c1a1b3f4e43fc86f488e8f6221057.txt
and they have exactly same (error?) lines.

Help, anyone? 

[Rob_Wilcox1]

Do you have some more info such as :-

Operating System on Mailbox Server.
Operating System on CAS.
Verify (and describe) the authentication types supported on each of the virtual directories you can see on the CAS and Mailbox Server.
Is your CAS just a CAS with a seperate server for mailboxes?  

Those are my initial thoughts...

[Wyldechild]

 Hi,

CAS+Mailbox are on same server (Win 2003 Enterprise  x64 SP2)
Here are Virtual directories of our mailserver:

Autodiscover (Integrated + Basic authentication)
EWS (Integrated + Basic)
Exadmin (Basic)
Exchange (Basic)
Exchweb (Integrated + Basic)
Microsoft-Server-ActiveSync (Basic)
OAB (Integrated)
OWA (Basic)
Public (Integrated + Basic)
Rpc (Basic)
RpcWithCert (Basic)
UnifiedMessaging (Integrated)

EV server is Win 2003 std and has a fresh install of EV 8.

[Wyldechild]

 Ok,
I made change to web.config:
<add key="EnterpriseVault_WebDAVRequestVirtualDirectory" value="owa"/> (default folder is "exchange" on Exch2003 but on 2007 default directory is "owa")
I also took Integrated authentiction off from IIS and now its Basic (This fixed my problem with Shared computer Outlooks Archive explorer ->opened empty)

now the error message changed:
WebDAVRequest::Send] Exception sending WebDAV request: System.Net.WebException: The remote server returned an error: (401) Unauthorized.
at System.Net.HttpWebRequest.GetResponse()
at Symantec.EnterpriseVault.Owa.ExchangeStoreAccess.WebDAVRequest.Send()

I didnt find any solution to fix this unauthorized error?
Need help....again

[mashles]

This wont help if you have mailbox and CAS on the same server but if they are seperate roles, try the following:

remove the line

<add key="EnterpriseVault_WebDAVRequestHost" value="localhost"/> (you might have changed localhost to something else)

Add this line:
<add key="EnterpriseVault_WebDAVRequestProtocol" value="http"/>


What these 2 changes will do is make the webdav request go to the mailbox server that holds which ever user has logged into OWA instead of itself (the CAS server). I have found this to be much more reliable than the webdav request going to the CAS, especially as some places like to lock down the webdav on CAS servers.

Hope that helps.

[Wyldechild]

CAS & mailbox are on same server so no help for me.
Luckily this is our companys testing enviroment not production...
I unistalled EV 8 and Installed EV8SP2 no help..
Where this Webdav request is sent. To some VD on EVServer?
