Deprecating Basic Authentication for Outlook Integration in Business Central

As announced in the Microsoft Tech Community, Basic Authentication for Exchange Web Services (EWS) will be decommissioned in October 2020. Dynamics 365 Business Central integrates with Outlook and Exchange, and these features allow the option of Basic Authentication with EWS. In response to the change in EWS, beginning October 1, 2020, the option to use Basic Authentication with these features will no longer be available. We will decommission the option as part of the 2020 wave 1 release of Business Central.

Who is affected?

The Exchange team will stop supporting and fully decommission Basic Authentication for EWS to access Exchange Online. The change does not affect any Business Central customers using Azure Active Directory (Azure AD) authentication for Business Central, including Business Central Online. So the customers that the change does affect are those who:

  1. Use NavUserPassword, Windows, or UserName as the Business Central authentication method, and
  2. Use Exchange Online.

What features are affected?

Business Central features that use Exchange Web Services and support Basic Authentication include:

  • Deployment of the Business Inbox in Outlook.
    The option is currently available to deploy the Outlook add-in from Assisted Setup and from Office Add-in Management. If the change affects you, you will need to deploy the Business Inbox in Outlook manually. You can do this either for a single Exchange account for individual users, or using centralized deployment for administrators. Note that this affects only the deployment of the add-in. Using the add-in will continue to work following existing authentication and functionality.
  • Synchronization of contacts in Business Central with Contacts in Outlook.
    This feature requires authentication through EWS, and will no longer be available with Basic Authentication.
  • Invoicing for Microsoft Bookings in Business Central.
    Similar to synchronizing contacts, you can synchronize customers and items with Bookings. The bulk invoicing feature in Business Central for bookings requires synchronization of contacts and items through EWS. So the feature will no longer be available with Basic Authentication.

Next Steps

We understand that decommissioning features can have an impact on your business. If you have comments or suggestions on improving our support of these features, please provide your ideas at https://aka.ms/bcideas.

Power Fx: Error handling graduates to preview

We are thrilled to announce that the long-time experimental feature Formula-level error handling has moved forward to preview. As a result, you and your end users will enjoy higher reliability and more transparency about what is happening in your apps. It’s a huge step. Adding error handling to an existing language turned out to be a very tall order, touching almost everything, from data types, to functions, to the runtime. Thank you for all of your support, feedback, and patience as we got this done. What does it mean for you? Your apps will more reliably detect and report errors.You can write blank/null values to a database.You can detect and replace errors with the IsError, IsErrorOrBlank, and IfError functions.You can control error reporting and logging at a central location with App.OnError.You can create and throw your own custom errors with the Error function. Error handling is a big change in behavior. By entering preview, we are signaling that we believe we are done, that we anticipate no further significant changes from here. Many of you already use error handling in production and this move to preview should only embolden more of you to do so. If significant changes are needed from here, we will treat them as a separate feature. We are rolling this out slowly as it is such a big change. All of you will soon see that the Formula-level error handling switch has moved from experimental to preview in the settings (as of version 3.22082). It will still be default to off for most tenants. Over the coming weeks we will slowly change the default for new apps only to on across the tenants. Makers can still disable this feature and will be able to do so for a long time. I say again: we are changing the default for new apps only. Existing apps will continue running as they always have. We have no plans at this time to turn this on for existing apps, and as this is such a big change, we may never do this and make this a permanently available switch. Your feedback will guide us. The documentation for Error, IfError, IsError, IsErrorOrBlank functions and the App.OnError property covers these changes. IfError and IsError are very similar to their Excel counterparts. We are also working on overview docs that will be released shortly. But before that, let’s take a brief tour. Let’s start with what Excel does, the inspiration for Power Fx. For an error like division by zero, Excel is very clear that something has gone wrong with a # error message that shows right in the cell. This error will propagate to other cell formulas if A1 is used in a formula: Today, without error handling, Power Apps won’t report anything in this scenario, instead treating the division by zero error as a blank value. That’s not good, as the maker and the end user of the app have no idea something may have gone wrong: Errors happen. Unexpected data flows in, networks go down, storage fills up, to name just a few situations that an app may encounter in the real world. Makers don’t often think through all the ways that things can go sideways which makes default error handling even more important. Returning a blank for an error is also a problem because blank is a legitimate value in our type system and in many databases. Without error handling, Power Apps won’t allow you to write a blank to a database instead thinking it is an error. So, instead of returning an easy to ignore or misinterpret blank value, with error handling turned on we now report an error to the end user (the error banner) and show the formula as having an error to the maker (the red filled in circle on the control): Further, if you look at the value of the formula, it is not a blank but an error value. Just as any formula can result in a blank, now any formula can also result in an error: Now, we still aren’t showing an error in the label control itself as Excel does. We couldn’t do this generically because, unlike Excel, the error could be on a property of a control for which there is no way to display the error. For example, where should an error on a slider control? Where should an error be shown for an imperative operation in the middle of a button’s OnSelect formula? We settled on showing the end user banner and flagging the control in the design experience. That’s not to say you can’t detect and display an error in that label control. Error handling provides a wealth of mechanisms to control how errors are handled and reported. For example in this case, we can wrap the division by zero with an IfError function to return a custom message in the label: The Text function call is required for type compatibility. Or we can use IfError to throw a different, more specific error with the Error function: Or we can have a catchall for all errors in the app with App.OnError. For example, we can log the error and present a different message to the end user: If we look at the log, we see the details of the captured error from FirstError (and there is also an AllErrors), including where it happened and when it was detected: The possibilities are endless! You now have all the tools you need to detect, replace, report, and log errors, including a good default behavior if you never take advantage of these tools. And, bonus, you can also now write blank (or null) values to databases. Please let us know what you think in the Power Apps community forum. There is a dedicated and active space for error handling discussions at Error Handling – Power Platform Community (microsoft.com).
