The IHS SDTS is a online web=based tool to exchange data securely between recipients inside or outside the IHS. The SDTS is accessible from any Internet connected device.

IHS employeess can originate data transfers to other persons inside and/or outside of the IHS. Persons receiving the delivery outside the IHS from an IHS user are afforded the ability to reply to the delivery sent to them. Users without an IHS email address cannot originate a new delivery.

No special software is required to use this service beyond a web browser, and it is compatible with supported version of Microsoft Edge and Google Chrome web browsers.

The use of groups or lists is not supported because of a number of potential problems this can cause. There are some scenarios in which sending to email distribution groups will work correctly if the group is in the IHS email Global Address List (GAL), but only listing each intended users individually is supported.

Because this service is integrated with the IHS Active Directory, IHS user account administration is handled outside of this tool. The "Change Password" functionality is only intended for non-IHS users who have created an account to access this service. If you need assistance with changing your IHS account password, please contact your local IT support.

The default quota is 500 Megabytes (MB) of space. That means that either a user can send 1 large file or many small files until the total amount of data stored is 500MB. If a user runs out of space, they can manage the other data stored by logging in and going to the "Manage Packages"; section

Quotas can be expanded for a period of time should there be a business requirement to do so. Requests will be handled on a case by case basis and should be sent through

By default, data sent through the IHS SDTS is accessible for 30 days, after which it will be automatically deleted from the service. You will receive a notification email 7 days prior to automatic deletion of any data you have sent. If you would like the data to be removed prior to 30 days, you can either delete the data by logging in and going to the "Manage Packages"; section of the website or by going to the "Show Options" section and setting the "Date expires" option when sending the secure data.

By default, recipients of data sent through the IHS SDTS can only reply to you the sender. If you would like to allow recipients to reply to all recipients, once logged in go to the "Show Options" section when creating a new Express Delivery and check the box to "Allow collaboration." When "Allow collaboration" is enabled, a recipient of the data has an additional button is available that allows the user to "Reply securely to all", which creates a threaded discussion viewable by everyone in the original submission. Files uploaded can be viewed and downloaded by everyone, and the user replying has the option to toad additional files to the discussion.

NOTE: With this enabled it is important to note that files saved to the discussion can potentially overwrite existing files in the discussion if the filenames match.

No, all data sent through the service requires the recipient to logon to retrieve the information sent.

If you receive this error message, simply select the "Back to Your Deliveries" link and you will be taken to a screen showing all your currently valid secure deliveries.
