Hey Mailop, It sounds like a lot of senders saw issues with Microsoft on September 4th, and open rates dropped but then recovered the next day.
We also saw issues starting on September 4th, but our IPs' reputation in SNDS hasn't recovered yet, and neither has our open rate to Microsoft domains. Has anyone else continued to see deliverability issues to Microsoft domains after September 4th? We're trying to gauge whether this is related to those more widespread problems or not. Thank you!
