CIO: Public Distribution Lists transitioning to in August

Page header - CIO update

The OneUSDA Email Transition team will begin transitioning Public Distribution List email addresses beginning August 1 in the next step of the OneUSDA email transition to

PDLs currently have a primary email address associated with the PDL, but after the transition, the PDL will have an address as the primary address.

Important details about this transition include:

  • No action is required by PDL owners, managers, or members. This transition will occur automatically.
  • PDL display names are not changing, and PDL users will not experience a visible change with this transition. For example, the display name of “FS-pdl asc all” will remain in Outlook’s Global Address Book and will still be displayed as such to email receivers.
  • Only the domain of the PDL’s associated email address is changing. The domain is the part of the email address that comes after the @. The domain will change from to The part of the address before the @ will not change.
  • The email address that is currently primary to all PDLs is not going away but will continue to operate after the transition as a secondary address associated with the PDL.
  • This change will not affect PDL member lists. Individual email addresses of employees who are members of PDLs have already transitioned to No action is required by PDL owners/managers regarding updating individual emails of PDL members.
  • The transition is expected to complete by August 15. If you have saved or published hyperlinks of PDL names in documents or web content, consider updating those links after August 15 to ensure the PDL hyperlink is up to date with the new address associated with the PDL.

What you need to do

Be aware of this upcoming transition, but no further action is required by PDL owners, managers, or members for this transition. All PDL users should consider updating saved or published hyperlinks to regularly-used PDLs after the transition completes.
