Exchange 2010 SP2 OWA Dutch translation issue part 2

Update: MS released the newest version of the Exchange 2010 language pack on 5/22/2012 which solves the issues as described in this blog. See Exchange 2010 Service Pack 2 Language Pack Available for Download.


In a previous blog I wrote about an Exchange 2010 SP2 OWA Dutch translation issue.


This issue is described in The word "Globale Adreslijst" in Dutch is displayed unexpectedly in breadcrumb and navigation pane in OWA in an Exchange Server 2010 SP2 environment.

Solution: install Exchange 2010 SP2 Language Pack Bundle on Exchange 2010 CAS Servers.

Important:

• Exchange 2010 SP2 Language Pack Bundle is ONLY for people with the Dutch OWA problem. No one else should install it.
• This Language Pack Bundle is only intended for Exchange 2010 CAS role to solve the OWA Dutch translation issue. So, install this Language Pack Bundle only on Exchange 2010 CAS or Multi-Role Servers. Don't install this LPB on Exchange 2010 Mailbox or HUB Transport Servers.
• If you have already installed this Language Pack Bundle on Exchange 2010 Mailbox Servers or Multi-Role Servers it will probably generate errors in Application Log (Active Directory entry for mailbox <name> contains an invalid locale for attribute MsExchUserCulture: nl-NL,en-US). Microsoft is working on a fix for this. Summary, if you have:
• CAS Server: installing LPB and no error events
• CAS/HUB Server: installing LPB and no error events
• CAS/HUB/MBX Server: installing LPB and error events (MS will provide a fix)
• MBX Server: installing LPB and error events (MS will provide a fix)

Remarks:

• All Exchange services will be stopped and disabled during installation of Exchange 2010 SP2 Language Pack Bundle. For DAG members follow directions in Installing Update Rollups on Database Availability Group Members.
• Installation takes about 20-30 minutes per server.
• See also What's new with Exchange 2010 languages support?

Install Exchange 2010 SP2 Language Pack Bundle:

1.       Download Exchange 2010 SP2 Language Pack Bundle
2.       Run LanguagePackBundle.exe

What do we see: the wrong translation ‘Globale adreslijst’ has been replaced with ‘E-mail’.

However, this translation is different from the original translation. With Exchange 2010 RTM/SP1 the OWA Dutch interface shows ‘Berichten’ instead of ‘E-mail’. I’ve asked Microsoft about this and for some reason they chose ‘E-mail’ instead of ‘Berichten’ as the original translation.

Simplify the Outlook Web App URL

Simplify the Outlook Web App URL describes Exchange 2010 SP2 OWA redirection.

I have the following comments regarding Simplify the Outlook Web App URL:

·         Section “Use IIS Manager to simplify the Outlook Web App URL when SSL is required”: I think MS means: Use IIS Manager to simplify the Outlook Web App URL when SSL is required at the Default Web Site? If so, step 12 says: In SSL Settings, clear Require SSL but SSL should not be cleared if you require SSL at the Default Web Site.

·         When configuring Require SSL (clear Require SSL) & Redirection settings at Default Web Site, the settings are propagated to lower-level directories. The steps to enable SSL on all sub dir’s (except OAB & PowerShell virtual dir) and disable redirection on all sub dir’s are not explicitly mentioned.

·         The following table contains default OWA SSL & Redirect settings (after installing new Exchange 2010 SP2 CAS Server):

Default IIS Settings E2K10 SP2 CAS Server	SSL Settings	HTTP Redirect
Default Web Site	[x] Require SSL	[ ] Redirect requests to this destination: <> Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
aspnet_client	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
Autodiscover	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
ecp	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
EWS	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)

Exchange	[x] Require SSL	[x] Redirect requests to this destination: /owa Redirect Behavior: [ ] Redirect all requests to exact destination [ ] Only redirect requests to content in this directory Status code: Found (302)
Exchweb	[x] Require SSL	[x] Redirect requests to this destination: /owa Redirect Behavior: [ ] Redirect all requests to exact destination [ ] Only redirect requests to content in this directory Status code: Found (302)
Microsoft-Server-ActiveSync	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
OAB	[ ] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
owa	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
PowerShell	[ ] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
Public	[x] Require SSL	[x] Redirect requests to this destination: /owa Redirect Behavior: [ ] Redirect all requests to exact destination [ ] Only redirect requests to content in this directory Status code: Found (302)

Rpc	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)
RpcWithCert	[x] Require SSL	[ ] Redirect requests to this destination: < > Redirect Behavior: (options greyed out) [ ] Redirect all requests to exact destination [x] Only redirect requests to content in this directory Status code: Found (302)

By default only Exchange, Exchweb & Public virtual dir are redirected to /owa. However, after enabling redirection at the Default Web Site and disabling at owa virtual dir you get in a loop and it’s not possible to restore the default configuration (only Exchange, Exchweb & Public virtual dir redirect to /owa):

·         When I enable redirection for default web site, the owa site inherits the redirection.

·         When I remove the redirection from owa it removes it from exchange, exchweb and public sites as well.

·         If I add redirection back to exchange, exchweb or public sites it gets copied to owa site as well.

·         See also comments at http://briandesmond.com/blog/redirecting-owa-urls-in-exchange-2010/

After some research I found a much easier way to get owa redirection working by using Custom Error Pages:

IIS Manager (Windows 2008 R2):

·         Default Web Site, Error Pages, Add...

·         Add Custom Error Page

o   Status code: 403.4

o   (*) Respond with a 302 redirect

o   Absolute URL: https://webmail.domain.com/owa

By using Custom Error Pages there is no need to configure IIS SSL & Redirect settings and things don’t get messed up.

 

When using https://webmail.domain.com users will see the default IIS7 Welcome page. To redirect https://webmail.domain.com to https://webmail.domain.com/owa:

·         Create a default.aspx in the root directory (C:\inetpub\wwwroot\default.aspx) with one line:

o   <% Response.Redirect("https://webmail.domain.com/owa") %>

·         IIS Manager:

o   Default Web Site, Default Document

o   Move Up default.aspx to the top of the list
