Exchange Sync For On-Premises Deprecation

In early January 2023, Microsoft altered Cloud-hosted Exchange Sync for Exchange Online/Outlook 365 to not allow Basic authentication. This disables the Exchange Sync for On-Premises Workplace Customers due to Authentication requirements.

However, this does not currently affect On-Premises Exchange Servers that do allow Basic Authentication. We recommend using our Outlook Add-In as this add-in will achieve syncing your Outlook Calendar events and Workplace Calendar Events the same as the Exchange Sync.
