Why is Mac Outlook Legacy not working today?

We are on version 16.83 and are still having this issue with Legacy Outlook.

How can I ensure that my team is able to update to build 7409.16?

None of our users are any higher than Version 15.20 (Build 7386.34). The Powershell command you mentioned before is showing that version for everyone, but our users are all on the latest version possible of Outlook.

I'm guessing that this Legacy version is hardcoded into the "New Outlook" version that is installed somehow? If not, how can I ensure that my users are on the latest update?

Dear Outlook Support Team,

I am writing to formally express significant concern regarding the absence of certain functionalities in the new version of Outlook that were integral to the legacy version. This deficiency has rendered me unable to efficiently conduct critical operations involved in multiple real estate transactions. The potential collapse of these transactions could result in substantial financial losses for all parties involved.

Given the severity of the situation and the imminent risk of considerable financial detriment, I urge your immediate action to restore these essential functionalities. Please be advised that failure to address this issue promptly may compel us to explore legal avenues to recover any resultant damages.

I trust in your understanding and swift resolution of this matter.

Thank you for your attention to this urgent issue.

Regards,

Jack

I'm on Legacy vs 16.83.1 and having the same issue with sync.

We are dealing with the same issue(s) described above. Looking for a quick resolution. The "new" Outlook doesn't include custom "groups" for your contacts like legacy does.
