This is a bit messy but i can be done like this:

1 Create user account with appropriate email address and set default password.
2 Create a contact with forwarding email address as “SMTP address”
3 Go to User account, Properties, Exchange General, delivery options, choose contact that was created for the final delivery address (the forward address)
4 Go to User account, Exchange advanced, Hide from address book.
5 Go to Contact properties, Exchange advanced, Hide from address book.
6 Disable user account. (It will never be used or logged into)

Problem: You have set up the ADC Connector and migrated your users and everything looks good. Then for some reason you need to delete and remigrate the migrated users you will run into a problem. The ADC will try to replicate with the deleted users and not with the new ones.

Reason: The reason for this is that the ADC writes an ADC-Global-Names attribute to the object in Exchange 5.5. This is a unique tag for each user and when you remigrate the users this will not be the same.

Resolution: Open Exchange System  Manager on Exchange 5.5 in raw mode and delete the ADC-Global-Names attribute.

Q: I have openened aditional mailboxes in Outlook. When I remove it it is still in my folderlist but I can’t find it in Tools | Services | Exchange Server | Properties | Advanced . How can I ger rid of it?

A: Start Regedit and go to HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfiles<Name of Outlook Profile>

Look through the subkeys till you find the one containing the name of the mailbox thar you want to delete. Remove that key and start Outlook.

Why does my Exchange 2003 server take 10 minutes or more to shutdown?

It seems that most users that install Exchange Server 2003 on a Windows Server 2003 machine that is also configured as a Domain Controller may experience a slow shutdown when they try to reboot/shutdown the server.

This is because the Active Directory related services shut down before the Exchange services, thus causing the Exchange services to fail repeatedly while looking for the DS. Exact and detailed explanations for this behavior and restrictions can be found in the KB articles listed below.

There are 2 known solutions for this problem (besides listening to me and NOT installing Exchange on a DC in the first place…). One is to change the timeout for a failed service to shutdown itself, and the second is to manually stop the Exchange services BEFORE shutting down the server.

Method #1: Services kill timeout
Follow these easy steps:

Run Regedit and navigate to

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlWaitToKillServiceTimeout

The default value of WaitToKillServiceTimeout is set to 600000. Change it to 20000.

Exit the registry editor and reboot the server.

Note: Changing the WaitToKillServiceTimeout value may have some undesired effects on other services, use this method at your own risk.

Method #2: Manually stop Exchange related services
The best choice is to manually shutdown the Exchange related services before trying to shutdown or reboot the server. You can do so manually by going to the Services snap-in in the Administrative Tools menu and stopping the specific Exchange related services, or, you could use a script.

Forms-based Authentication

Exchange 2003 has a snazzy new feature called Forms-based Authentication, which I’ll refer to as FBA. FBA is the new logon security feature for Outlook Web Access (OWA) which is disabled by default in Exchange 2003.

Why use FBA?

There are several security benefits to running FBA:

1. If the session is inactive for a period of time, the session will expire. The only way to gain access again is to re-authenticate. More on this later.
2. Users can no longer click the Remember my password check box in Internet Explorer.
3. Like the session inactivity setting, if you log out, you really log out. The only way to gain access again is to re-authenticate. Previously in Exchange 2000, the user had to complete the logout session by closing the browser window.

Enabling FBA

Enabling FBA is a simple process performed in Exchange System Manager. First, you should note that you need SSL enabled on the target Exchange 2003 server. When you’ve done that:

1. Drill down to your server object in ESM.
2. Under the server object, expand the Protocols container.
3. Under the Protocols container, expand HTTP.
4. Bring up the properties of the Exchange Virtual Server.
5. Click the Settings tab. Here you will see the option to enable FBA.

Here’s what you should see. Note that this option is greyed out on a cluster server because FBA isn’t available on a cluster. You’ll need a front-end server in this scenario.

You will also note an option for compression. I’ll leave that subject for another article. I’ve recently enabled FBA in a front-end back-end scenario here at my office. Note that FBA only needs to be enabled on the front-end server in this scenario.

If you’ve done everything correctly, you should get the following new OWA logon screen. Note that one difference is the fact that your users will now need to enter domainusername when logging on, or they can use their UPN if they prefer. There are ways around the domainusername sequence by modifying the logon.asp page, but these changes will be lost when you perform upgrades or re-installations. I think I’m going to leave this as it is for now – it’s not much for users to learn, after all.

A Choice of Experience

The first option on the FBA screen is for you to select your choice of client experience: Premium or Basic. The Premium client gives you the full new OWA interface, whereas the Basic client gives you a cut-down version with less features. As you might guess, the Basic client is somewhat faster due to it offering less features. Hopefully that may help those still using dial-up connections to their OWA mailbox. If you’ve never seen the basic client, here’s a quick screen shot.

Tweaking Security Options

Also on the opening logon screen are two options surrounding the security of the session: Public or shared computer and Private computer. The Private computer option assumes you are accessing OWA from a trusted computer, such as a computer within your normal office, your home, or perhaps from a partner site where you trust the other workers! The Public or shared computer option is for those situations where you are accessing OWA from a non-trusted network, such as an Internet cafe or other public area.

The difference between the two options is how long the inactivity timeout will last. With the Public or shared computer option, the timeout is 15 minutes by default. With the Private computer option, the timeout is 24 hours by default. These values can be modified via the following registry keys:

HKLMSystemCurrentControlSetServicesMSExchangeWEBOWATrustedClientTimeout
HKLMSystemCurrentControlSetServicesMSExchangeWEBOWAPublicClientTimeout

Both are DWORD values, and are set in minutes. For both, the minimum value is 1 and the maximum value is 43200, which translates to 30 days.

By the way, in case you’re curious, I understand that the timeout will not kick in during long message composition!

What About ISA?

What if you are using ISA in your DMZ and you publish OWA?

When I enabled FBA on my front-end server, I had the following message pop up:

This message indicated that I could offload SSL to the ISA server, or so I thought. Great – no need for an SSL certificate on my front-end server. Wrong! It’s my understanding that you have to have SSL enabled on both the ISA and the front-end server for FBA to work. I did try without SSL on the front-end, all to no avail.

I’m not saying that this is a bad thing. In fact, bridging SSL across the DMZ has to be a good thing as far as I can see. I just found the above message a little misleading. Or maybe it’s just my interpretation, but it’s one to watch for, anyway.

FBA is an extremely useful addition to OWA in Exchange 2003. It gets my vote!

How do I grant the administrator(s) (or any other user) full mailbox right on Exchange 2000/2003 mailboxes?

In Microsoft Exchange Server 5.5, when you grant Service Account Admin privileges on the Site container to a Microsoft Windows account, you grant that account unrestricted access to all mailboxes. Because Exchange 2000 and Exchange Server 2003 do not use a service account, even accounts with Enterprise Administrators rights are denied rights to access all mailboxes, by default.

This means that Exchange Full Administrators do not have the right to open any mailbox found on any server within the Exchange organization.

In fact, if your logon account is the Administrator account or is a member of the Domain Admins or Enterprise Admins groups, then you are explicitly denied access to all mailboxes other than your own, even if you otherwise have full administrative rights over the Exchange system.

However, unlike Exchange Server 5.5, all Exchange 2000/2003 administrative tasks can be performed without having to grant an administrator sufficient rights to read other people’s mail.

This default restriction can be overridden in several ways, but doing so should be in accordance with your organization’s security and privacy policies. In most cases, using these methods is appropriate only in a recovery server environment.

Granting right to a specific mailbox

Use the following procedure to grant access to an Exchange 2000 or an Exchange 2003 mailbox:

Note: You must have the appropriate Exchange administrative permissions to do so.

1. Start Active Directory Users and Computers.
2. On the View menu, ensure that the Advanced Features check box is selected.

Note: This is not necessary on Exchange Server 2003 because of the fact that the Exchange Advanced tab is exposed by default.

3. Right-click the user whose mailbox you want to give permissions to and choose Properties.

4. On the Exchange Advanced tab, click Mailbox Rights.

5. Notice that the Domain Admins and Enterprise Admins have both been given Deny access to Full Mailbox access.
6. Click Add, click the user or group who you want to have access to this mailbox, and then click OK.
7. Be sure that the user or group is selected in the Name box.
8. In the Permissions list, click Allow next to Full Mailbox Access, and then click OK.

9. Click Ok all the way out.

Warning: If the Group or User name list is empty and you only see one line with the name of SELF – do NOT touch the permission settings before you read SELF Permission on Exchange Mailboxes.

= Bad!

= Good

Note: If the purpose of granting such access is to permit use of the EXMERGE utility (see Delete Messages from Mailboxes by using EXMERGE for an example of such a requirement), grant Receive As permissions. You can also grant Full Control permissions if you want complete access.

Granting right to a mailboxes located within a specific mailbox store

Use the following procedure to grant access to Exchange 2000 or an Exchange 2003 mailboxes found on a specific mailbox store:

Note: You must have the appropriate Exchange administrative permissions to do so.

1. Start Exchange System Manager.
2. Drill down to your server object within the appropriate Administrative Group. Expand the server object and find the required mailbox store within the appropriate Storage Group. Right-click it and choose Properties.

3. In the Properties window go to the Security tab.
4. Click Add, click the user or group who you want to have access to the mailboxes, and then click OK.
5. Be sure that the user or group is selected in the Name box.
6. In the Permissions list, click Allow next to Full Control, and then click OK.

Note: Make sure there is no Deny checkbox selected next to the Send As and Receive As permissions.

7. Click Ok all the way out.

Granting right to a mailboxes located on a specific server

Use the following procedure to grant access to Exchange 2000 or an Exchange 2003 mailboxes found on a specific server:

Note: You must have the appropriate Exchange administrative permissions to do so.

1. Start Exchange System Manager.
2. Drill down to your server object within the appropriate Administrative Group. Right-click it and choose Properties.

3. In the Properties window go to the Security tab.
4. Click Add, click the user or group who you want to have access to the mailboxes, and then click OK.
5. Be sure that the user or group is selected in the Name box.
6. In the Permissions list, click Allow next to Full Control, and then click OK.

Note: Make sure there is no Deny checkbox selected next to the Send As and Receive As permissions.

7. Click Ok all the way out.

Note: It might take some time before the changes you’ve made will take effect. The amount of time needed is influenced by the number of domain controllers, Global Catalogs and site replication schedules and intervals. On one domain with one site containing multiple domain controllers it might take up to 15 minutes before you can begin using these new permissions. On single servers that are also DCs you can speed up the process by restarting the Information Store service.
