Relevant Products: Signature Manager Exchange Edition | Exclaimer Cloud - Signatures for Office 365
You have Send-As permissions that allow you to send messages to another user from a shared mailbox. Although, a signature is added to the outgoing email, but when you view the sent message in the Sent Items folder you notice the signature is not present on the email.
Exclaimer uses a Sent Items Update feature to store sent messages (in your Sent Items folder) exactly as they were received, that is, showing the message and the appropriate signature that was applied (after the signature/mail disclaimer policies were applied).
The Sent Items Update feature can be configured to:
- Only store sent items with signatures applied
- Store the original messages AND a copy of those messages with signatures applied
To resolve this issue, you can change the mailbox that items sent from a shared mailbox are saved to.
To change the settings and place sent items in the associated Sent-As mailbox, you can use any one of these methods below:
- Set a registry value on the Outlook client to allow users to make the change themselves. This needs to be completed per user (that is, for anyone using the Send-As option). It ensures that the sent items are placed in the associated Sent-As mailbox, instead of the sending user's Sent Items.
This method requires Outlook to run in cached mode.
- Configure the mailbox, to save a copy of the message to the Sent Items folder of the shared mailbox, for an on-premises Exchange Server. This method allows an administrator to apply the setting to the mailbox; this means that anyone using the Send-As option for that mailbox will have a copy of the sent item placed in their own Sent Items folder AND a copy will be placed in the associated Sent-As mailbox.
This method does not require Outlook to run in cached mode.
Setting a registry value on the Outlook Client
To change which Sent Items folder is used, set the DelegateSentItemsStyle registry value on the Outlook client.
To update the Windows registry:
- Launch the RegEdit (Registry Editor).
- Browse to the following registry subkey:
Where, x.0 represents your Office version (example: 16.0 is Office 2016, 15.0 is Office 2013, 14.0 is Office 2010).
- From the Edit menu, select New then select DWORD (32-bit) Value.
- Enter the DWORD name as DelegateSentItemsStyle and press [Enter].
- To edit the value, you can either right-click the DelegateSentItemsStyle and select Modify or double-click DelegateSentItemsStyle.
The Edit DWORD (32-bit) Value window is displayed.
- In the Value data box, type 1.
- Click OK to save the changes and close the window.
- Restart Outlook for the change to take effect.
