M365 Changelog: SharePoint & OneDrive External Sharing One-Time Passcode mails will now come from [email protected]

MC394980 — Updated June 27, 2022: Microsoft has updated the content below to show as intended.

In order to improve delivery reliability of the one-time passcode e-mails that are sent as part of the external sharing flow in OneDrive and SharePoint, Microsoft will be updating the sending address for these mails from [email protected] to [email protected]. No other e-mails sent from OneDrive or SharePoint are being changed at this time.

When this will happen:

This change will begin rolling out late July and Microsoft expects rollout to be finished by late September.

How this will affect your organization:

This change should result in improved delivery reliability for all customers, and their partners, who use external sharing in OneDrive and SharePoint today.

What you need to do to prepare:

You may need to update your documentation or review your mailbox policies. Please ensure that the domain notify.microsoft.com is in the allow list for your mailbox policies

Please note, if your organization is using Azure B2B Integration with SPO, this change will not impact your organization.
