I understand your frustration around this situation and I apologize for it. As you might imagine we also wanted to have this resolved as soon as possible (it it’s not good for you it’s also not good for us), however, we needed to do so in a way that really addressed the underlying issue. As per the latest update on the status page incident the migration of free accounts is also now completed.
In summary (and I will be mostly repeating what’s available through the status page in a condensed form) the situation is that production accounts associated with paying tenants identified at the start of the incident had been migrated (before any others as you will sure understand) except for a few that exhibited a metadata usage pattern that warranted individual review and were addressed/contacted individually.
The situation for free tenants is similar from the perspective that tenants have been migrated. However, there were some restrictions on the type of user searches that can be made in order to safeguard against similar issues. In the status page incident there’s more information about what to do if you are affected by those restrictions and you can also directly reference me (at least for the remainder of this week; I’ll be offline on the next ones) in any question posted in this forum related to particular issues that you still experience with user search.
