Outlook EAS broken with version 2401

Outlook EAS broken with version 2401

I have several clients (at separate locations) that have recently had their outlook updated.

Since the update, they can no longer receive emails through EAS. I can send emails just fine through outlook but no incoming mail comes in.

Microsoft® Outlook® for Microsoft 365 MSO (Version 2401 Build 16.0.17231.20194) 64-bit 

I have confirmed that rolling back to the previous version of outlook does fix the issue. So far every user that has had their outlook updated encounters this issue.

Any advice would be super helpful. Thank you!

I've pasted the EAS log below:

*boot, Outlook/16.0 (16.0.17231.20036; x64) 2024-02-05T15:36:16.178Z, msync.zoho.com, myemail@mydomain.com

Is there any way Zoho can count the number of CONTACTS for a particular ACCOUNT and have a field in the ACCOUNT module update itself automatically? Currently we use Zoho to administer our language school and the Contacts represent students and Accounts represent Grupos (Classes). It would be very useful for us to have a feature like this enabled, and I can see other similar applications requiring something like this. The solution would be even better if the Contacts met a specified criteria,
