PostalOne!® Mandatory Software Update This Weekend

The United States Postal Service® (USPS®) is issuing a mandatory software update for the PostalOne! production system this weekend. This update will be implemented on Sunday, January 25, 2015. The PostalOne! Production (PROD) system will not be available on Sunday morning January 25, 2015, between 12 midnight and 10 a.m. CT. PostalOne! will also be updating the Test Environment for Mailers (TEM); that update will occur on Monday, January 26, 2015. The PostalOne! TEM environment will not be available between 6 a.m. and 4 p.m. CT on January 26.

Why the update?
The USPS periodically makes updates to the PostalOne! system to incorporate enhancements and bug fixes. Major updates are performed when there are significant changes to postal rates and/or regulations, such as when the USPS increases their prices, which is typically done in January (although this year is an exception). There are usually at least four PostalOne! software updates during the year: January, April, July, and October. There may also be interim updates to PostalOne! for immediate fixes or other system issues.

Details of the changes for this update may be found on the USPS RIBBS® web site for the January 2015 changes.

Handling Change
When these types of changes are announced, it is important for mailers to pay attention to the outage periods so that you can make adjustments in your mailing operations to accommodate the downtime. It is also extremely important for mailers to download and install the USPS Mail.dat Client software (also sometimes referred to as MD Client or MDR Client) as soon as it is available. This software can be downloaded from the Business Customer Gateway web site. Mailers also need to make any associated updates or configuration changes to software that interfaces with PostalOne! once their Mail.dat Client software is updated. For example, if you use DAT-MAIL’s eDocs Manager Plus or EDM10X, you will need to edit the configuration for this in the Window Book Automation Scheduler.

The USPS sends out notifications of all PostalOne! outages and software updates using the DMM Advisory. You can subscribe to the DMM Advisory by sending an email to In addition, detailed information regarding the changes in the PostalOne! software are available on the USPS RIBBS web site. Also available on the RIBBS site are the planned release schedules for these updates.

Window Book offers our Professional Services to users who may need assistance to download and install the Mail.dat Client software from the USPS, or to make any necessary updates or configuration edits to your Window Book software when these PostalOne! updates occur. Clients who use our EDM10X software don’t need to worry about updating the USPS MDR Client software, EDM10X will do that for you automatically!
