Changing Outlook Web App 2010 Timeout Values…

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 CAS server. If you have more than one CAS, the change has to be made on all CAS servers.

Launch registry edit and navigate to the following location. HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSExchange OWA

Change the DWORD “PublicTimeout” / “PrivateTimeout” and put the required value in minutes. If the DWORD doesn’t exist, create them. My example shows the timeout value to be 480 (minutes), which is 8 hours.

Exchange Forms-Based Authentication service has to be restarted for the changes to take effect.

msExchDelegateListLink Issue Has Been Fixed…

I had written before about the new feature in Exchange 2010 SP1 which auto maps the mailboxes in Outlook 2010, for which the user has full permissions, read here. Though it is a good feature and it works, it gave issues when the permission to a mailbox was removed. The problem was that the msExchDelegateListLink wasn’t getting updated and hence Outlook 2010 had all mailboxes listed (including the ones you don’t have access to) mapped.

This issue has been fixed, but I am not sure in which rollup. I am running Exchange 2010 SP1 UR5 in my lab and the msExchDelegateListLink is updating properly. Let me explain with the help of an example.

I have a mailbox (Shreya) with a number of mailboxes auto mapped, for which she has full access.

I removed her full access from my mailbox (Rajith).

Re-launching Outlook 2010 picks up the change and the mailbox has been removed, including the archive mailbox that was mapped.

Everyone has the same experience? Anyone else have an issue where it doesn’t update? If so, which rollup are you on?

Personal Archive For Resource Mailboxes in Exchange 2010…

I had a question today in my email asking as to why a personal archive is needed for resource mailboxes in Exchange 2010. At first, I thought that is not possible. My reasoning was that the developers would have surely thought about it and blocked the option to create a personal archive for resource mailboxes. But to my surprise, they haven’t!

I can’t think of any reason why you need a personal archive for resource mailboxes. Just to make the point clear, I have created a room mailbox called “Meeting Room One” in my lab.

Right clicking the room mailbox shows the option to enable the archive.

Enable archive for resource mailboxes

You surely can create an archive for resource mailboxes.

To answer the question that I got, I can’t think of any reason why it is still enabled. May be the developers missed to hide it!
