Updated October 06, 2022: As a reminder Tenants will have until January 2023 to review and take action on any entries in the Safe Links Block List that were unable to be migrated. Any entries that are unable to be migrated will be marked as such and organizations will have the ability to resolve that entry and run the migration again. In January 2023 the Safe Links Global Block List will be retired.
We have stopped the automated migration efforts to migrate all entries from your Safe Links Block List to the Tenant Allow Block List. Organizations will have the ability to review and take action on the entries that were unable to be migrated. Any entries that are unable to be migrated will be marked as such and organizations will have the ability to resolve that entry and run the migration again. Tenants will have until January 2023 to complete this activity, at which point the Safe Links Global Block List will be retired.

Note: Any entry migrated from the Safe Links Block List to the Tenant Allow/Block List will adopt the behavior of TABL. This means that any message with the URL present will be moved to Quarantine. If deleting an already migrated entry from TABL, it needs to be removed from BlockURLS to avoid migration.
As a reminder beginning in June tenants will no longer have the ability to add to the Safe Links Block List in the Global Setting menu. Then we will attempt to migrate the Safe Links Block List to the Tenant Allow Block List (TABL) on behalf of the organization. Any entries that are unable to be successfully migrated, they will be marked as such in the Block List and organizations will have the ability to take action as needed beginning in July.

Another update will be sent closer to July as a reminder for tenants to review the migration status of the Block List. Beginning in June organizations will no longer have the ability to add to the Safe Links Block List in the Global Setting menu. Following this, we will attempt to migrate the Safe Links Block List to the Tenant Allow Block List (TABL) on behalf of the organization. For any entries that we are unable to migrate, they will be marked as such in the Block List and organizations will have the ability to take action as needed.
[When this will happen:]
Early June: Organizations will no longer have the ability to add to the URL/Domain entries to the Safe Links Block List in the Global Settings flyout and we will attempt to migrate all the entries in an organization's Safe Links Block List to TABL on their behalf

Mid-June through December: Organizations will have the ability review entries that were not able to be migrated and resolve the issue(s)
January: The Safe Links Block List will be retired
