PeopleSoft (the system of record for Stanford faculty and staff addresses) does not accept address deletions from StanfordYou. If you delete an address in StanfordYou, the next time your info is synchronized with PeopleSoft, the deleted address will come back.
Contact your Human Resources Administrator to have the old address permanently deleted from PeopleSoft. Alternatively, you can copy your current home address over an old mailing or temporary address.
Students must maintain their addresses in Axess.
