DLP Outlook Add-in analysing messages in Outbox

Hi recently upgraded our DLP to 11.6.0.762. I am running Office 2016 on a windows 10 1909. Everything was working fine until the DLP upgrade. some users were saying their emails were hanging trying to send messages.  And due to the nature of the correspondence and the importance of the users involved we simply removed the client and everything worked fine. It has started happening on my machine now. and one common thing I have noticed is on closing outlook all those affected were getting the following Pop Up message:

"You have messages in your outbox waiting to be analysed by McAfee DLP. If you exit now they won't be analysed until the next time you start outlook" it gives the following options then to "Exit and Analyse Later" or "Do not Exit".

Have clicked on "do not Exit " and left it at least 15 minutes. Outbox is empty last email sent has sent and been received successfully and still the message pops up when I go to close outlook. When I proceed to exit and analyse later the issue we can run into Outlook hanging when we send emails - but not always. Anyone else seen similar or have an opinion on this?

Re: DLP Outlook Add-in analysing messages in Outbox

Hello and thank you for posting here!

We have had a few reports of similar issues which is currently being investigated by our DLP engineering team. As a follow up question, do you have the Outlook Background Processing feature enabled? This can be found in the Windows Client Configuration policy under Email Protection. This feature is new to 11.6. When enabled, it creates a hidden folder in Outlook which is meant for temporary storage when DLP scans outbound emails. This replaces the old behavior where emails were scanned prior to being sent to the outbox which sometimes caused performance issues when large attachments were present.

We are also experiencing the same issue after upgrading the DLP agent to 5.6.6 version. We notice the DlpOutbox folder is showing when we try to move emails to other folders. When we checked, there is no such folder exist in our outlook.

We tested moving a sample email to this DlpOutbox folder but later we couldn't find the email anywhere in the outlook. 

I have raised SR <4-21617210421> with support team to troubleshoot the issue

Good Morning @Satish_Talatam

Thank you for posting here. 

As my colleague had mentioned this is a new feature relating to DLP 11.6. The email will appear in the "DLPOutbox" folder whilst the email and attachments are scanned by DLP for sensitive content.

You can view the hidden DLPOutbox folder by enabling the following registry key on the endpoint machine then restarting Outlook:

[HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\DLP\Agent\Debug]
"DlpOutboxVisible"=dword:00000001

If the installed Office/Outlook is 64bit, the above key should also be added to the WOW6432Node:
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\McAfee\DLP\Agent\Debug]
"DlpOutboxVisible"=dword:00000001

I hope this helps.

Re: DLP Outlook Add-in analysing messages in Outbox

Hi,

I have a similar issue. I need to release an emails from the DLP Outbox automaticaly after the emails were scanned. My customers have an emails in the DLP Outbox few days and they are still notified via pop-up about persist scanning.

 

Best Regards,

 

Pavel

Hi @Former Member 

Is there a way to disable the feature? We would like to get the emails analyzed in Inbox folder instead of analyzing in Dlpoutbox folder.

Re: DLP Outlook Add-in analysing messages in Outbox

Hello,

We have same issue upgraded our DLP to 11.6.0.762. More and more clients gets message:
"You have messages in your outbox waiting to be analysed by McAfee DLP. If you exit now they won't be analysed until the next time you start outlook"

We tired to enable and disable "Outlook Background Processing feature" but result is same.

Also i could not find mentioned workaround. There is no setting named "disable background scanning" in:
Policy catalog > Windows Client Configuration > Edit the policy applied to your endpoints > Email Protection

Can you please specify workaround?

Regards.
Juris

Looked at the DATA Loss Prevention 11.6 > Windows Client Configuration > Default Client Configuration 

The Enable Background Processing option was, and is, unticked . 

 

So that is neither the problem nor a solution

Hi Kirk ,

Do you know if the next version of HDLP will solve the problem in question? When can it appear in the production version?
