Microsoft have decided to make the E5 Developer Subscription available to only new developer subscriptions. Can this be made available to existing developers?

https://developer.microsoft.com/en-us/sharepoint/blogs/new-microsoft-365-e5-subscription-with-ems-now-available-for-developers/

The new subscription model is now for 90 days with auto renewal as long as there are "active developer activities" but it's written nowhere what exactly is an "active developer activity".

Please then explains in detail.

For example, create a sharepoint site? Add a webpart to a page? Deploy a spfx solution in the app catalaog?

On my Office 365 Dev Subscription, I am trying to do a PoC for Azure AD joining Windows 10 machines. But that requires an intune subscription. I think you will get more development work out of EM+S products, if you include it with the dev subscription.

In Excel API, I can't choose cells based if they have formulas or values.

In VBA, I can do that by using Range.SpecialCells method. Also, I can specify if I want to get only text values, numbers, errors and/or booleans.

Please, support this for Excel JavaScript API, because currently, I'm looping all the worksheet's used range rectangle to get the values, and my loops spend a lot of time skipping blank cells.

We would like to have array formula support available in the office.js API. We use these heavily in our VSTO Excel Add-in in combination with user defined functions to display function output in multiple cells. Having this feature available would allow us to build the Excel Office Add-in we would like to build.

For other forum browsers, here is an example of an array formula.

Please note that while Binding.setDataAsync() in the office.js API supports adding formulas to a range of cells, you cannot see or edit the formula after adding.

There is no way to access office 365 developer program benefits. The link sent in the activation email points to the page that does not exist. There is no page with links to particular benefits as well.

I'm re-opening this idea (https://officespdev.uservoice.com/forums/224641-feature-requests-and-feedback/suggestions/12947451-support-mac-compose-in-add-ins) that was posted in March and replied to in October of this year. Compose add-ins are NOT supported on the 2016 Outlook Mac client as far as I can tell (I'm running v15.29 (161115) with Office Insider Fast); Compose add-ins ARE available in Word, Excel, etc. but not Outlook. Please let us know when and if that will be remedied. Thanks!

I've posted about this here:
http://answers.microsoft.com/en-us/office/forum/officeonline-word_online/content-control-support-in-word-online/0f33ba70-9fe0-4990-9f09-db5ce7f3a8c7?tm=1460747722010

The JavaScript API provides a lot of functionalities around Content Controls, so I don't really understand why these are not supported in Word Online.

Will we have this support eventually? Do we have any estimated date for that?

Please add the ability to create, delete, and modify Excel Comments on specific cells using Office.js

We would like to create an add-in for Outlook that executes automatically for all new messages without requiring the user to manually activate it.

The ability to update, delete and insert into the Named Item Collection items for excel named ranges.

I would be nice to have a way to get online editor url for a document in order to be able to share to others this url through the word add in

Allow user to install plug-in with the option to auto-run the app (or plug-in as the option to turn on auto-run) so the user doesn't have to active the plug-in each time.

The new support for adding ribbon commands for Excel task pane add-ins is a good start. However, it will be even better if we can have programmatic access to these buttons. At the very least, the add-in should be able to update visibility and label. Ideally, the add-in could create buttons on the fly and control most properties. Thanks.

Currently getFileAsync function works in Powerpoint desktop and Powerpoint iPad, so it is natural to extend it to Powerpoint online. Actually, in reference page https://msdn.microsoft.com/en-us/library/office/jj715284.aspx (section "support details"), it is mistakenly stated that it works in Powerpoint Online.

Please provide the ability to customize the Excel ribbon from Office.js (in a task pane add-in).

Add a new tab that appears when workbook is active
Add new ribbon buttons to custom tab
Hook button click event to execute app logic
Set label, tooltip, icon, etc.

Enhance the Office add-in javascript APIs (for Excel) to allow the add-in to programmatically make cells in the worksheet read-only.

Our use case requires that our add-in be able to populate a table in the worksheet with values, but some of the values should be read-only for the end-user. (In our COM/VSTO add-in we toggled worksheet protection off/on to accomplish this).

See this forum post for the origin of this suggestion:

I suggest you offer Office 365 as part of MSDN subscriptions.

I was extremely disappointed to see that when I login to my MSDN subscription and search for "Office", I don't see Office 365 listed as an available download.

I pay for my MSDN subscription out of my own pocket, so the absence of Office 365 from MSDN subscriber downloads is a large impediment.

You can't test user permissions and other things with a single admin user. Running as admin isn't really best practice when developing. Agreed?

Some key links on this page are broken, which makes it hard for developers to get help.
(1) dxipfb@microsoft.com bounce email back, because it only accept emails from within Microsoft.
(2) "Give feedback about this page" link at the bottom of the page links to no where. So it can't be used to provide you feedback at all.
