AD objects not being synced from HQ to Branch and viceversa (Message Tag) (4273358)

QCS email messages are tagged with a stamp ([EXTERNAL]) in the subject by a Security Mail Gateway third party tool. When QCS encrypted emails are tagged from the subject, attachment or body, QCS detects that the message has been manipulated and synchronizations are not performed.

The Mapimsal logs shows the next behavior when emails are received and processed:

Attachments Names(8200) = Multi-value[1]:
        0

Attachments Streams(8205) = Multi-value[1]:
VT_ERROR or unable to convert to string

From(8) = QCS_ServiceAccount@company.com

CONFIDENTIALITY NOTICE(Disclaimer Text): This email message including all attachments to it, is intended for the sole use of the person(s) to whom it is addressed. It may contain information that is privileged, confidential, or legally protected. Any unauthorized review, use, disclosure, or distribution of this information is strictly prohibited. If you have received this information in error, please contact the sender by reply email and delete the original message.

    Size(3) = 25162
    Subject(8) = [External] {AEA4959D-48B5-41CC-98FC-177321584A36}
    Type(8) = ExchangeMessage

RESOLUTION:

1. Create an exception rule for Inbound and Outbound emails generated by QCS service accounts for HQ and Branch to avoid stamping the message with tag in the Subject, Attachment or Body fields.

2. Use a whitelist to isolate QCS Service Accounts email accounts.

3. Remove Disclaimer Texts for QCS Service Accounts.
