Anyone else seeing mailboxes with Exchange Online 2 showing they now have 150gb?
Noticed this this morning. I understand that Basic was going to go to 100gb as they roll that out, but did they also increase Exchange 2 to 150gb to make it still worth paying for it vs an archive license? Or is this a glitch that is going to give us a problem later when people blow through the limit and MS corrects it?
This example mailbox is licensed with Business Basic, then Exchange Online added on. It now shows 150gb. I'm seeing this for every user in every tenant I have looked at so far.

The 150 GB figure across your tenants does not match Microsoft’s documented primary-mailbox limits. Business Basic is listed at 50 GB and Exchange Online Plan 2 at 100 GB; the published limits do not describe those licenses as combining into a 150 GB primary mailbox. The archive is separate. Because the portal screenshot may reflect a display or provisioning change, verify the enforced values in Exchange Online PowerShell with Get-EXOMailbox for one affected user and inspect IssueWarningQuota, ProhibitSendQuota, and ProhibitSendReceiveQuota. Confirm the assigned service plans and whether an archive is enabled, then check Microsoft 365 Service health and Message center for a rollout notice. Until Microsoft updates the service description or confirms the change, plan against the documented 100 GB Plan 2 limit and avoid growth beyond it. If PowerShell also reports 150 GB, open a support case with affected tenant examples.
