Updated April 9, 2025: We have updated the content. Thank you for your patience.
We would like to inform you that the rollout of Request for Comments (RFC) compliance enforcement changes, originally announced in January 2025 (MC987329) have been postponed until May 2025.
With the compliance update in May 2025, the "From" field of voicemail email messages will be modified to meet the latest RFC standard. Specifically, RFC 6854: Update to Internet Message Format to Allow Group Syntax in the "From:" and "Sender:" Header Fields. According to this standard, the Internet message format must always include an address in the "From" header. For example:
Previously: +44 28 7584 5695 <442875845695>
After the change: +44 28 7584 5695 <noreply@skype.voicemail.microsoft.com>
[When this will happen:]
General Availability (Worldwide, GCC): We will begin rolling out early May 2025 and expect to complete by mid-June 2025.
General Availability (GCCH, DoD): We will begin rolling out mid-May 2025 and expect to complete by mid-June 2025.
