Shared Mailboxes Send on Behalf

I have created shared mailbox and Grant Send On Behalf permission for John.
John sends email on behalf to shared mailbox but messages look like John send message himself (Send AS). But John have only Grant Send on Behalf permission not SendAS.
Exchange 2013 CU2.
Truly, Valery Tyurin

Hello,
I have similar issue but in reversal, I have a shared mailbox. I want to send an email on behalf of shared mailbox but I do not want the recipients to see the email has been sent by "User on behalf of shared mailbox". I have been added as a delegate
with editor permissions in shared mailbox. If I send an email (From option: shared mailbox) from my outlook, receiver can see that the email has been sent on behalf. I do not want this. It should be visible as if the mail is sent from shared mailbox.
I saw some suggestions that adding permissions on exchange server will help but I dont know where to check in the system (perhaps I dont have admin rights). I have a colleague, they are just new, they dont know about email box too. My old friend who left
has configured the outlook for these new ladies. For them it is absolutely working fine. I dont know what he did but would not have used exchange server (as we dont have admin rights).
Please help!
Regards,
Krishna

Shared mailbox - send as and auditing Exchange 2007

Got 3 users A,B,C who all access a shared mailbox X.
They have a requirement to be able to answer emails sent to mailbox X BUT the return address to be X (i.e. not their own or send on behalf etc) so any subsequent relies still go to X and not the individual email addresses.
However, enother requirment is that there needs to be a way to determine which user (A, B, or C) actually sent the email from shared mailbox X.
Any way at all to do this?

Hi,
Since the full access permission has been assigned to users, please give Send As permission to these 3 users (A,B,C) for this shared mailbox X. Then user A,B,C
can send as the mailbox X with the From field shown as Mailbox X. Please follow these steps to set it:
1. Make sure the Full Access permission have been configured correctly.
2. Give send as permission to UserA, UserB and UserC for shared mailbox X.
Add-ADPermission -Identity “Mailbox X” -User UserA -Extendedrights "Send As"
Add-ADPermission -Identity “Mailbox X” -User UserB -Extendedrights "Send As"
Add-ADPermission -Identity “Mailbox X” -User UserC -Extendedrights "Send As"
3. Then UserA, UserB and User C can send messages by the following steps in Outlook:
a. Click New Email > OPTIONS > From, then the From field is shown in the message.
b. Click From > Other E-mail Address, and select the Mailbox X.
Then the recipients would receive the messages which the From field is shown the Mailbox X name instead of UserA, UserB or UserC.
To track which user has send as Mailbox X to the recipients, we can enable message tracking log or
Mailbox audit logging to track it.

Mail from Excel using a Shared Mailbox issue

Hello,
We have Office 365 running with several shared mailboxes. We configured the value DelegateSendItemsStyle so when you send an email it will be placed inside the shared mailbox send item folder. (See KB:
http://support.microsoft.com/kb/2181579). So far so good.
When we send directly from an Office application like Excel (File -> Share -> E-mail -> Send as Attachment), in the new email window we change the From field to a shared mailbox, type our text and send the mail. Now the file will be placed
inside the users send items folder.
Somehow when we mail directly from Word/Excel the DelegateSendItemsStyle gets overruled and ignored. When we change the shared mailbox to a payed one with a license, add the box as a second Exchange account and send the mail then, everything is ok and the
mail will be placed inside the shared mailbox send items folder. As you might understand, with 25 shared mailboxes it is a waste of money to license them all.
I contacted Microsoft Office 365 support, and this is outside of their support scope.
Any ideas how we can fix this?
Thanks in advance.
Kind regards,
Max

Hi,
Please read the kb 2181579 again, we can find the following information:
The functionality is available only when the Exchange account is set to
Use Cached Exchange Mode. The DelegateSentItemsStyle registry value does not affect an Exchange account that is configured in Online mode.
When you said "add the box as a second Exchange account", did you mean "additional Mailbox"?
Go to File -> Account Settings -> Account Settings -> Double click on your account name -> More Settings -> Advanced -> Make sure "Use Cached Exchange Mode" and "Download shared folders" have both been ticked -> OK.
Kindly check the result.
Thanks,

Send As from a shared mailbox stopped working

I have created a Shared Mailbox a few months ago and gave one use full access rights and send as permissions. This worked perfectly since it was created. On Friday, the user started getting:
Delivery has failed to these recipients or groups:
You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission.
If the problem continues, please contact your helpdesk.
There have been no changes made to any of the rights or permissions anywhere. The shared mailbox properties still show this user in the full access and send as list. The shared accounts address is available in the GAL so that is not an issue.
Any ideas would be appreciated. I could probably recreate this mailbox, but would rather fix the issue or at least know what happened in case it does it again.
Nick Laurino

Hi,
Have you tried removing and then re-adding the permission for the user? Worth a try when such issue occurs.
As the administrator, you may want to verify that the user actually does have "Send-As" permission on the shared mailbox. To do that,
Open the Exchange Management Console on the Server
Navigate to Recipient Configuration > Mailbox and right click the Shared Malibox
Select "Manage Send As Permission"
Check that the user is listed in the permissions
To solve the issue on the client side, delete the offline address book and allow Outlook to recreate it.
Close Outlook
Delete the Offline Address Book folder
It can be found under "C:\users\{username}\AppData\Local\Microsoft\Outlook\Offline Address Books"
Open Outlook and it will download a fresh copy of the Offline Address Book
I hope this can be helpful.

Shared mailbox conversation view; on behalf sent items

Update rollup 4 for SP2 introduced the possibility to have a sent item stored in the shared mailbox on behalf of who you sent it.
Now this works ok, sent items in fact are saved in the sent items folder of the shared mailbox.
But if you put that shared mailbox inbox in conversation view, the sent items are not shown in the conversations. This makes it hard to follow a conversation (as it was before).
Is this a known issue ? By design ? Existing workaround ?

Hi,
Based on my test, after setting by the following KB, I can see all messages which is send by others in Sent Items of Shared mailbox. It also works in Conversation View.
The sent message is not saved in the Sent Items folder of the shared mailbox
http://support.microsoft.com/kb/972148/en-us
As for your issue, please check the DelegateSentItemsStyle value in regedit and make sure your Microsoft Exchange account is set to
Use Cached Exchange Mode to see whether the issue persists.
Thanks,
Winnie

Send as not working on shared mailbox in Exchange 2010

Hello,
Please follow the Riaz J.Butt's suggestions.
Besides, I recommend you restart IIS services to check the result.
Please check if this user has send as permission in ADUC.
Please open ADUC, click View, choose Advanced Features, choose the shared account under Users, right-click the shared account and then choose Properties, choose Attribute Editor, check msExchDelegateList value.

Outlook 2010 Shared Mailbox Outbox Send Immediately Issue

Hello,
So we have a weird problem tat we have being trying to diagnose for a while and I think that I have finally got to the bottom of the problem, just now need to find a solution.
We have a shared email email account. This is set up as shared mailbox in exchange (2010) with Full Control and Send On behalf of privileges given to three users. Each of these users has added this shared mailbox
as a second account to their outlook (2010) profile.
The Problem we have appears to be two fold. For some reason emails are not sent immediately for this account even though this is value of the setting in outlook. This puts an email in the shared mailbox outbox. We then have a race condition where by the
first user of the shared mailbox whose outlook client does a send an receive first becomes the user who sent the email on behalf of the shared inbox rather than the user that hit sent. This has caused mild confusion for the recipients as signatures of the
email does not match what outlook is displaying.
So, firstly is this expected behaviour for shared accounts, that the outbox is shared so this race condition will always exists?Secondly, any idea why on this second mailbox attached to outlook emails are not always sent immediately? In fact this appears
to be a bigger problem, email not getting sent until people hit send and receive has just happened to someone else. What can I do to diagnose this issue?
Cheers
Rich

Hi,
Based on the description above, the issue is that when you send an email message from a shared mailbox, the sent email message remains in your Outbox until you manually perform a Send/Receive operation.
As far as I know, this problem occurs when both the following conditions are true:
Your Outlook profile is configured in online mode (not cached Exchange mode).
You have the DelegateSentItemsStyle registry value set to
1.
If you are using Online Mode, please switch to Cached Exchange Mode to check the result, if the issue doesn't occur then, please note there is no resolution to this problem other than to either switch your profile to cached Exchange mode or set the DelegateSentItemsStyle
registry value to zero (0). Additionally, if your mailbox is located on Microsoft Exchange Server 2010 (or later), the Exchange administrator can configure similar behavior on the server.
Important
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it,
back up the registry for restoration in
case problems occur.
To change the value of DelegateSentItemsStyle to 0 in the registry, follow these steps:
Exit Outlook.
Start Registry Editor.
In Windows 8 and Windows 8.1
Swipe in from the right to open the charms, tap or click Search, and then type
regedit.exe in the search box. Or, type regedit.exe at the Start screen, and then tap or click
regedit in the search results.
In Windows Vista and Windows 7
Click Start, type regedit in the Start Search box, and then press Enter. If you are prompted for an administrator password or for confirmation, type the password, or click
Allow.
In Windows XP
Click Start, click Run, type regedit, and then click
OK.
Locate and then select the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\<var>x</var>.0\Outlook\Preferences
Note In this key path, the placeholder <var>x</var>.0represents
15.0 for Outlook 2013, 14.0 for Outlook 2010,
12.0 for Outlook 2007, and 11.0 for Outlook 2003.
Select the DelegateSentItemsStyle value.
On the Edit menu, click Modify.
Type 0, and then click OK.
Exit Registry Editor.
Start Outlook.

Email remains in the Outbox when you use the DelegateSentItemsStyle registry value

Is there a way to create a rule that sends and Auto Response for a shared mailbox?

I have a shared mailbox set up that receives emails that are sent to 3 different addresses:
[email protected]
[email protected]
[email protected]
I would like to create a rule that would send an auto response when someone emails one of these addresses. However, I don't want an auto response sent to [email protected] so I can't just set up an "out of office" reply for the mailbox.
Is there a way that I can create a rule to send an automated response to 2 of the 3 addresses?
Nate

Hi
we can enable the shared mailbox in ADUC and create Outlook rules for it in Outlook to achieve it. please follow these steps:
1. In Active Directory Users and Computers, right-click the shared mailbox and click Enable Account.
2. Configure the Outlook account for the shared mailbox in Outlook.
3. Click Rules > Manage Rules & Alerts.
4. Create a rule like the following format:
Apply this rule after the message arrives
Have server reply using a specific message
Except if the subject contains specific words
Select exception(s) (if necessary) of the Outlook Rule - (“except if from people or public group“)
5. Apply the auto reply rules for this shared mailbox.
Then users can receive auto reply of the shared mailbox except the exceptions we have set when they send messages to this shared mailbox.

Outlook send as from shared mailbox

HI all,
I have a problem with sending email from a shared mailbox on user accounts. The sent items go to the sent items folder on of the sender, but I want them to go the Shared mailbox sent items (so that other user can see a reply has been sent).
Now I have been searching on Google and found these steps:
To do this, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Preferences
On the Edit menu, point to New, and then click DWORD Value.
Type DelegateSentItemsStyle, and then press ENTER.
Right-click
DelegateSentItemsStyle, and then click Modify.
In the Value data box, type 1, and then click OK.

Full Access and Send As are two different things. Granting Full Access does not confer Send As. In fact, Full Access is granted on the mailbox in the mailbox store, while Send As is granted on the mailbox's user object.

Okay, that is what I thought. (The internet lied to me) I added myself to the Syssupport mailbox with full access AND send as permissions and I received the test email so now that is working. Thank you for clearing that up.

How to add a 'Send on Behalf Of' address to multiple mailboxes?

My apologies if this is a repeat question. I've searched for a while now but haven't come across an answer.
This is my dilemma:
My company is using a piece of software that has a 'sender address'. This address needs to be added to the users' mailbox in the 'Send on Behalf Of' field. Is there anyway to automate this process? Can I make this happen through a GPO or a security group
or something? It would be very tedious to have to do this for every account and every newly created account.
Thank you for your help!

Not all ideas are possible. :(
I think it's very simple script for PS Exchange, c planned launch times a day.
$DistinguishedName = Get-DistributionGroup MyGroup | Get-DistributionGroupMember
$DistinguishedName | ForEach-Object {Set-Mailbox -Identity user_mailbox -GrantSendOnBehalfTo @{Add = "$_"}}

Email stuck in outbox if sending mail from a shared mailbox

Hi,
Some user mailboxes have recently been migrated from Exchange 2003 to Exchange 2010. Shared mailboxes are located on Exchange 2003 still for the time being.
Some users have send as permissions to a shared mailbox. In Outlook the users are logged in as themselves and using the from field send an email from the shared mailbox.
The email is sent and delivered to its recipient.
The email is however stuck in the outbox of the users mailbox.
I have tried recreating the Outlook profile, windows profile and using a different PC, but the mails still get stuck in the outbox.
If outlook is changed to use cached mode then the emails are delivered. We don't want customers using cached mode though.
If I migrate the shared mailbox to Exchange 2003 I still have the problem.
If I migrate the users mailbox to Exchange 2003 then the problem goes away.
On the Laptop I am testing this on it is Windows 7, Office 2003. I have also tested on another computer with Windows 7 and Outlook 2007. Outlook safe mode doesn;t help or turning off windows firewall.
Has anyone experienced a similar issue?

Outlook 2013 / Exchange 2013 : Shared mailboxes - Mail stuck in outbox (non-cached), Mail sends but doesn't get received (cached).

Hello,
We are currently experiencing some weird behaviour in Outlook 2013 since we added Shared Mailboxes.
When we run Outlook 2013 with cached mode
enabled:
- I create a new e-mail and send it.
- The e-mail goes to the outbox, and get's 'send'.
- None of the recipients receives the e-mail.
When we run Outlook 2013 with cached mode
disabled:
- I create a new e-mail and send it.
- The e-mail goes to the outbox, but remains there.
Now to make things even more bizarre:
When I switch from 'cached'-mode to 'non cached'-mode, I see all the e-mail that were 'send' in cached-mode stuck in the outbox.
Note: The DNS server configuration in Exchange is correct.

Hi,
How about sending on OWA? Does the issue exist?
To troubleshoot the issue, let's run Outlook in Safe Mode to determine if 3rd-party add-ins are related:
Press Win + R and type “outlook.exe /safe” in the blank box, then press Enter.
If there’s no problem sending emails in Safe Mode, disable the suspicious add-ins to verify which add-ins caused this issue.
Please also disable the firewall and anti-virus program to send the emails again, in many scenarios the protection may cause the issue.
Please also keep Exchange and Outlook patched to the latest.

Can't send on behalf of a mailbox, unless it is added as an account to Outlook

As the title states i can't send on behalf of one of our new IT Support mails. I've added myself to the delegate access in Exchange. We are running Exchange 2010. Here comes the weird part.　I can't send on behalf for some reason, but if i add the IT Support
account to my Outlook, I suddenly CAN send on behalf of it. This makes absolutely no sense to me whatsoever. And to make matters worse, i tried testing if this was the same for all mailboxes. I made a new test mailbox, and added myself as delegate (i.e. same
settings as the IT Support mailbox) and nothing else. This time it worked WITHOUT adding the account to my Outlook. I realize this is a workaround, but i want to be able to send on behalf of our IT Support mail without having to add it to Outlook for every
user that needs to use it. Anyone have any suggestions as to what is wrong? And how to fix it?

Hi,
If you want to send on behalf of the IT Support mailbox, please make sure the following settings have been configured in Exchange:
1. Open Exchange Management Console, expand Recipient Configuration > Mailbox.
2. Right-click IT Support user > Properties.
3. In Mail Flow Settings tab, click Delivery Options > Properties.
4. Make sure your account is listed in Send on behalf permission list. If not, please add it. If it does, please remove your account, Apply it. Then add it back to have a try.
Then check whether the issue persists.

When I add users as managers or to send as in shared mailboxes I get the test username applied

I have two users [email protected] [email protected], Both users were added to the test group with onmicrosftonline.com as [email protected] and [email protected] The .temp was removed when we went to our own domain now
when I add jane.doe to a shared mailbox I see the jane.doe.temp for the send as but full access displays her name correctly. When I add John.Smith as a manger he is displayed as John.Smith.Temp.
Thank you.

Sending From Shared Mailboxes bounce back or underliverable

Exchange 2013 CU6
Issue with Outlook 2007 and Exchange 2013
When a user sends as a shared mailbox (e.g Mailroom) they either gets the do not have permissions or they get a bounce back message.
1. User would get you do not have permissions then 5 mins later it will work again and same for the bounce back. Any issues with CU6 with sending from shared mailboxes?

Hi,
From your description, I would like to clarify the following thing:
The issue will occur if the address in the From box is automatically populated by using outdated, locally cached information when User A typed User B's address.
You can follow the steps below for troubleshooting:
1. In the new email message in Outlook, click From, and then click Other Email Address.
2. In the Send From Other E-mail Address window, click From, change the address book to the GAL, and then select the user to whose mailbox you were granted Send As permissions.
Hope this can be helpful to you.
