A recent update to the office.js api seems to have introduced an issue with Office.context.document.addHandlerAsync.

Running previously working code (Online Only, desktop excel seems ok) now gives a strange error, 'Function addHandlerAsync has invalid parameters'.

This can be replicated using the example on the api doc page here, hitting Try Me and just running the default code will show the message.

It also appears to have affected Office.context.document.removeHandlerAsync.

Similar to the Desktop and Online (Office 365) versions, the office applications hosted on Office Web Apps or Office Online Server should support Office Add-in (javascript)

For example, currently you can run the add-ins in Word Online (hosted on Office 365) but running Word Online hosted on Office Online Server the add-in functionality is not available.

When inserting a file from a base64 string into the body with the method "InsertFileFromBase64()" it does not include continious section breaks. It uses page breaks instead. It would be nice to have those working also.

The enhanced Excel-specific APIs available for developing Office Add-ins that run with Excel 2016 are a nice start. There are some key missing APIs. One area in need of extending is eventing. For workbooks that contain multiple worksheets, it is critical for the Add-in to be able to determine when a worksheet is activated/deactivated so that the Add-in's UI can adapt accordingly. Similarly, the Office Add-in should be able to hook an event so that when the workbook gets closed/shut down (and maybe Saved), the Add-in can persist in-memory state into the workbook.

Allow add-ins to specify a hook which when correctly detected within an incoming email can trigger an alert making the user aware of the availability of the add-in.

Outlook for Windows supports a (legacy) MAPI property called WebViewUrl which loads a web-page when viewing that folder.

Support OfficeJS in this scenario to create a folder-based full-view app in Outlook.

I keep having issues with my email account send emails to my recent contacts, without my permission, often including a link to my OneDrive Photographs.

In the Excel 2016 JavaScript API any Undo action by the user in the sheet causes BindingDataChanged event to fire even if the undo doesn't impact the bindings data.

If there a lot of bindings in a single sheet this could impact the performance to the user since the event will be called unnecessarily.

please add some simple examples of using an odbc data source.

Would like to be able to use macros when file is uploaded to Excel Web.

When you batch a number of commands prior to calling RequestContext.sync(), it can take what appears to be a long time with no feedback on progress. This is particularly evident when inserting images which need to be converted. Having the option to specify a progress function callback would give developers an opportunity to keep their users in the loop and avoid cancellations of actions.

Allow add-ins to specify a hook which when correctly detected within an incoming email can trigger an alert making the user aware of the availability of the add-in.

Office 365 shared mailboxes are very useful. Unfortunately, they do not load outlook web add-ins right now: see http://stackoverflow.com/questions/35059067/make-outlook-add-ins-working-with-office-365-shared-mailboxes/35065215?noredirect=1#comment57867973_35065215
This would be terrific to have add-ins for such mailboxes especially for all CRMs related apps.

The enhanced Excel-specific APIs available for developing Office Add-ins that run with Excel 2016 are a nice start. There are some key missing APIs. One area in need of extending is the ability to use Named Styles defined in the workbook - to be able to apply them to ranges via the Javascript API.

Example from this page does not work currently:
https://msdn.microsoft.com/en-us/library/office/fp161062.aspx?f=255&MSPPError=-2147217396#bk_support

document.addHandlerAsync for DocumentSelectionChanged event returns with error 5001

Also the problem is mention in this MSDN question:

The situation is we want to automaticlly add and choose specific theme for certain type of the document that has certain rules in font and size. So, can you help?

The maximum of 450 for the RequestedHeight element in the schema manifest is not quite large enough. There may be scenarios where the UI needs to cover the entire Reading Pane. Form Regions in the Outlook client already support a complete replacement option for some Outlook items. Add-in Express also has this feature for their Advanced View and Form Regions. Maintaining consistency would be best for all design scenarios and migration from other platforms.

I tried in Chrome, Edge and IE. There is an angular.js error in the JavaScript console.
