I had the same problem.All you have to do is follow this article from msexchange.org and this KB article from microsoft.
Just make sure you follow the instructions exactly as they are provided.
Hope that helps!

I had this same problem on my server. I finally fixed it by applying hot fix KB831464, going back through the instructions on 327000, and waiting a few hours for security permissions to propogate.

You are giving proper delegation of the mailbox through Outlook right?

In Outlook on the Boss's machine, goto Tools -> Options. Click on the Delegates tab and add the secretary with proper permissions.

I haven't read anywhere that this has been done, so I can't assume that this has been done, so if you have done this, please don't flame me... [Smile]

Actually why is this necessary adding a delagate in Outlook? The MS knowledgebase says nothing about any configeration on the client side?

This I thought was only for "send on behalf" and not what I want "send as".

Am I right is saying this?

Thanks for the reply Corey....

Has anyone found the solution for this? Most of the MS articles refer to Exchange 2000, not 2003. We recently migrated our server from windows 2000 server and exchange 2000 server to windows 2003 server and exchange 2003. It worked perfectly before the change out. Any ideas?

Hi,
i had the same problem. My solution is clear the cached mode in Outlook.

We found a lot of problems while working with cached mode (working with custom forms e.a.).

I hope i find a better solution so we can work with cache mode.

It is funny...we are having the EXACT same problem. We got around it by doing the "Send on Behalf", but I don't like that solution. I'll be reviewing all your suggestions and if any of them work, I'll let everyone know.

I have found a solution. If you open a user accounts properties, click on the security tab, click on advanced, double click the SELF entry, and check the tickbox beside "Write All Properties". Click ok 3 times and your done. You should now be able to open that users outlook and add someone to the delegates. The delegate should also appear magicly in the send on behalf for the user.
The only thing you have to work out is how to apply this to all users.

This sounds totally crazy and I am not too sure why it worked, but it did for me. If you click "From" and choose the person from the Global Address List it works after that.
I dunno why, but it worked for me!

I'm also having the same issue. My account has full ex admin rights with send as and receive as allowed. The only way I can get it to send as, is to add the account to the domain admin group. The domain admin group is still set to deny send as/receive as.
Anybody had any luck yet?

Hi All,

I think you may all be assigning your users as Domain Admins or Administrators. The listed knowledgebase article works for ordniary users, but Domain Admins (and some other Admin Groups) have send as explicity denied - deny overrules allow.

check this
http://support.microsoft.com/?kbid=327174

doesnt apply to me as Im on 2003, but I still suffer from the same problem - configured "send as" and I get the "cant send on behalf" error.
Questions:
1.What does "remove all other permissions" in the prior posts step-by-step mean?
2. what is the default time for the "mailbox store cache to flush"
3.What replication are they referring to AD or..?
4.If this is a security setting, why would it be dependent on such a huge factor as stopping/starting the Store.

I just noticed that one article said apply it "to this object only" and the last one I posted said apply it "to this object and all child objects" I changed mine to this object and all child objects and now it works.

I found this solution on another website:
Assigning "Send As" Permissions to a user
It was brought to my attention that following the steps listed in KB327000 (http://support.microsoft.com/?kbid=327000), which applies to Exchange 2000 and 2003, to assign a user "Send As" permission as another user did not appear to work. I too tried to follow the steps and found that they did not work. I know this feature works, so I went looking around for other documentation on this and found KB281208 (http://support.microsoft.com/?kbid=281208) which applies to Exchange 5.5 and 2000. Following the steps in KB281208 properly gave an user "Send As" permission as another user. But I found the steps listed in KB281208 were not complete either. The additional step that I performed was to remove all other permissions other than "Send As". Here are the modified steps for KB281208 that I performed (changes noted in blue):
1. Start Active Directory Users and Computers; click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
2. On the View menu, make sure that Advanced Features is selected.
3. Double-click the user that you want to grant send as rights for, and then click the Security tab.
4. Click Add, click the user that you want to give send as rights to, and then check send as under allow in the Permissions area.
4.5 Remove all other permissions granted by default so only the send as permission is granted.
5. Click OK to close the dialog box.

So after I verified that the steps for KB281208 worked, I was curious as to why the steps for KB327000 did not work. What I found was that Step #7 of KB327000 applied to the permission to "User Objects" instead of "This Object Only". Here are the modified steps for KB327000 that I performed:
1. On an Exchange computer, click Start, point to Programs, point to Microsoft Exchange, and then click Active Directory Users and Computers.
2. On the View menu, click to select Advanced Features.
3. Expand Users, right-click the MailboxOwner object where you want to grant the permission, and then click Properties.
4. Click the Security tab, and then click Advanced.
5. In the Access Control Settings for MailboxOwner dialog box, click Add.
6. In the Select User, Computer, or Group dialog box, click the user account or the group that you want to grant "Send as" permissions to, and then click OK.
7. In the Permission Entry for MailboxOwner dialog box, click This Object Only in the Apply onto list.
8. In the Permissions list, locate Send As, and then click to select the Allow check box.
9. Click OK three times to close the dialog boxes.

The KB articles were updated to include correct information. But, if you had problems with this in the past, this might be why!

Thanks for tracking this down. I spent several hours tracking this one down myself.

Thanks so much for providing this. I've been chasing this problem since I started at my help desk job in November. Any idea why this way works and the other doesn't?

# re: Assigning "Send As" Permissions to a user
The reason the previous way was not working was because the permission was not being applied onto the appropriate objects. The "Apply Onto" option controls inheritence for the specified permissions. Previously, the "Apply Onto" option was being specified as "User Objects" which was incorrect.

# re: Assigning "Send As" Permissions to a user
Another question,

When I apply these permissions to a user, they seem to disappear within a day. For example, I'll follow the steps listed here, and then come back in several hours, or the next day, and the user that I granted Send As permission to is gone from the list of Security settings. Any idea why?

# re: Assigning "Send As" Permissions to a user
Hmm, I do not know of anything off the top of my head that would be doing this.

I would start investigating this by enabling "Object Access" auditing for the Active Directory Objects. You will have to go in and edit the default GPO for the domain controllers to enable success auditing for Object Access. After this setting has taken affect, you will then need to view the "Security" tab of the user in question and adding a new auditing entry to audit any writes to the user object. Once that is completed, whenever the specific object is modified you should see a 566 event being logged in the Security Log of the Event Viewer. This should give you some good information on who/what is modifying the object and what is being modified.

Hello,
Spend a lot of times on this problem but all your messages help me a lot. This is the solution which is working for me.

1. Start Active Directory Users and Computers; click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
2. On the View menu, make sure that Advanced Features is selected.
3. Double-click the user that you want to grant send as rights for, and then click the Security tab.
4. Click Add, click the user that you want to give send as rights to, and then check send as under allow in the Permissions area.

5. on the client side give also the permission "send on behalf" for the mailbox you want to use.

It works fine now even if i notice that the permissions "send as" have disapeared again from AD !

Not sure if this is the default, but domain admins has the 'send as' permission for all domain users. How do I take this away as we don't want our DAs sending out on behalf of users (this has happened by accident a couple of times when they have the From: line showing in Outlook). Is this a Group Policy or somewhere else? Also, one of our admins is an Exchange Administrator, but I cannot give her permission to a mailbox as 'full control' is denied and grayed out. This is the same for domain admins...how can she keep another mailbox open in her Outlook profile and have such strong permissions in Exchange, but not be able to do the simple task of adding another mailbox to that profile. Any help on these are appreciated!

I had the same problem after migrating all our mailboxes from Exchange 2000 to Exchange 2003

Interestingly I only had the problem when using an Outlook client (2000 & 2003). I didn't get the problem when using Outlook Web Access.

The following this article resolved it for me.

http://support.microsoft.com/kb/327000#XSLTH3150121122120121120120

It didn't work straight away so I went for lunch and when I came back, tried it again and hey presto it worked.

This is the same for domain admins...how can she keep another mailbox open in her Outlook profile and have such strong permissions in Exchange, but not be able to do the simple task of adding another mailbox to that profile. Any help on these are appreciated!

There are two seperate ACLs that must be satisfied before permission to operate on many exchange objects is granted.

Firstly, there is the "Directory" level permission. This is the security tab on the objects within AD Users & Computers. By default, Domain Admins have complete control over all aspects of directory objects, so they typically have full control (including Send As and Receive As rights) as listed in AD.

However, there is a second layer of ACLs that must be satisfied. These ACLs are stored in the Configuration container, and can be viewed by using ADSIEDIT.MSC, or other similar tools. You can see (and delegate) a portion of these permissions in the Exchange System Manager at the Organization, Administrative Group, Server, and Store level in the System Manager. However, there are some levels that don't show the security tab unless you put in the correct registry entry on your machine that is running the System Manager.

Specifically:

quote:

HKeyCurrentUser\Software\Microsoft\Exchange\EXAdmin

Create new DWORD key: ShowSecurityPage
Set value to 1.

Regardless, this shows the permissions, but doesn't allow you to change them. The System Manager forces you to use the Delegation Wizard to do so. You can sidestep this by directly editing the Configuration container data with adsiedit, but I highly recommend against it unless you know EXACTLY what you are doing. You can completely hose your Exchange Organization if you aren't careful. You will become intimately familiar with the Configuration container if you ever have to build an offline forest/organization to restore from old backups, as getting the Administrative Group name correct takes some LDIF work if the name isn't First Administrative Group.

Anyhow, back to the security issue: Domain Admins have DENY Send As set by default on the store level, which means that even if the object's Directory permission for Send As are good, a Domain Admin trying to Send As should be denied by the store. Thus, you shouldn't have to do anything to prevent Domain Admins from abusing (accidentally or not) the Send As permission. Furthermore, internally Exchange Administrators and Full Exchange Administrators have DENY Send As and Receive As, so they cannot act as users indiscriminately either.

Anyone who has used ExMerge will know the hoops you have to jump through in order to extract and merge mailboxes from the exchange store. Specifically, to merge you need to have Send As rights and you need to be able to enumerate Exchange store information. Thus, the recovery account needs to be a member of Exchange View Only Admins, and then be assigned rights on the store being restored to. I generally temporarily give Full Control at the store level to the recovery account while I'm using it, then remove the rights when I'm finished. (And then disable the recovery account in AD so that it cannot be accidentally used for any reason.) The recovery account does not need any administrative rights on the Directory side, just on the Exchange side... and there only at the store level.

These denials of permission were specifically put in place to prevent the kind of overarching administrator abuse that you're worried about. In order to abuse the system, one has to have permissions to create AD accounts, create associated mailboxes, then delegate specific permissions to them in order to circumvent the default security applied to adminstrator groups and objects. (However, your dual AD/Exchange admin can easily grant themselves access to a mailbox and config their client to open it as another profile. It is implicit that these people are the most trusted individuals in the organization, because they have access to just about everything if the security model is the default microsoft permissions.)
