Is SmartPOP2Exchange compatible with Microsoft's OAuth2 for Office365?
Unfortunately, the use of Office365 accounts in SmartPOP2Exchange is currently no longer possible.
Our implementation of two-factor authentication using OAuth2 has not been working recently.
Since there have been no changes to SmartPOP2Exchange during this time, everything points to a change in the Microsoft interface. Unfortunately, no changes have been documented by Microsoft in this regard and we have been referred to the use of a software library which we unfortunately cannot use in SmartPOP2Exchange for technological reasons.
We are considering removing the OAuth2 authentication feature completely from SmartPOP2Exchange in an upcoming release, but are waiting to see if there are any further changes to the interface from Microsoft.
