Exchange 2010: Creating a secondary OWA Site with Integrated Authentication

In some cases it may be necessary to have the default OWA site require manual authentication (forms based or basic), specifically if your users use it to access multiple Exchange accounts. At the same time, I have found myself trying to become less dependent on fat clients and try to rely on thin clients where available and functional. And having Integrated Authentication turned on for OWA makes using that interface much more convenient for daily use.So...in that case, it is necessary to create a secondary OWA site in...

Enable OWA Light In Exchange 2013

How to enable the light version of OWA in Exchange 2013?   By default, the option to enable the light version of OWA is not exposed in OWA 2013. It is easy enough to light up the option, if you want it for any reason. Get-OWAVirtualDirectory | Set-OWAVirtualDirectory –LogonPageLightSelectionEnabled $true will do the trick. Run iisreset for the changes to take effect. --> Please see the rest on the blog : http://www.howexchangeworks.com/2013/03/enable-owa-light-in-exchange-2013.html

Microsoft Exchange 15 to include offline OWA access: Sources

What’s coming in the Exchange Server 15 component of Microsoft’s next wave of Office wares? Here’s some scuttlebutt from my sources. There’ve been a number of leaks about some of the products in the coming Office 15 wave. But there’s been nothing (that I’ve found, at least) about Exchange 15, the next version of Microsoft’s on-premises e-mail, calendaring and contacts server. Until now, at least. I’ve been collecting any tidbits I could find from my contacts with access to the Office 15... [Lire la suite]

OWA Cross-Site Silent Redirection in Exchange 2010 SP2

y now, many of you have seen the articles that discussed Address Book Policies, hosting changes, and the Hybrid Configuration Wizard, but deep down I know you all have been hoping that we would discuss the most sought after feature that we decided to include in Exchange 2010 SP2. What’s that you say?  Yes, I know, Tony said that the “new features in SP2 are unlikely to cause much of a fuss” and that there are not that many new features in SP2 (I believe his exact words were “relative paucity”) in his SP2...

OWA Mini In Exchange 2010 SP2...

Exchange 2010 SP2 brings a lightweight browser based client, called OWA (Outlook Web App) Mini and is designed to be used in mobile phones.It is pretty much like the OMA in Exchange 2003.

Changing Outlook Web App 2010 Timeout Values… A question I got today by email is to list the steps to change the OWA

A question I got today by email is to list the steps to change the OWA 2010 timeout values. The exchange admin who had sent me the email knows that when a user selects “public computer” in the OWA session, the timeout is 15 minutes by default and 8 hours if “private computer” is selected. He wanted to change the public timeout to be 8 hours as well. Though it is not recommended to have long timeouts for public sessions, below are the steps. To make any changes to the OWA 2010 timeout (public or private), it is a registry edit on the... [Lire la suite]

Exchange 2007 SP3 and OWA S/MIME Version Mismatch

In the recently released Exchange 2007 Service Pack 3, there’s a version mismatch between the Outlook Web Access (OWA) S/MIME Control, an Active X control used to provide S/MIME support in OWA. After you install SP3, users who have the control installed will get prompted to install the latest version of the control. The way this works – the code compares the “Version” property of the client S/MIME control (MIMECTL.DLL) on the user’s computer with the ProductVersion property of the MSI file (OWASMIME.MSI) on the Client Access...
