Today my Office 365 account is behaving strangely. Yesterday I was able to activate my wsp solution using activate button from the ribbon in solutions gallery.

Today I can not activate my wsp solution. It gives blank in popup dialog box. (As shown in below image)

When I click activate button, nothing happens.

Note: My user has full rights and it is site collection administrator.

  • Sandboxed solutions containing code has been depricated in SharePoint Online for some time now, is this such a solution? If so, MS might have started enforcing the no-code-policy fully Jul 29 '16 at 5:45
  • Yes, it's containing my event receivers in my solutions. Then how would I attach my event receivers to my list? Jul 29 '16 at 5:46

    That's probably the problem then! In SharePoint Online you need to use the add-in model, more precisely a provider hosted add-in with remote event receivers in this scenario Jul 29 '16 at 5:47
  • Have you tried by activate it using SharePoint Online Management Shell ?or through code/console application enter link description here Jul 29 '16 at 5:53
  • Thanks for your quick reply. As I've searched on google but can not get official announcement by Microsoft for enforcing the no-code-policy. Can you do one favor to provide me that link? Jul 29 '16 at 5:55

Upon further updates, it appears this is intentional and they are finally making good on their statement from 2014. http://ow.ly/zeMz302MKN1.

Code in sandboxed solution has been depricated by Microsoft in SharePoint Online for some time now, see Deprication of custom code in sandboxed solutions.

So that is the most possible reason for what you are experiencing.

They are now starting to enforce the no-code-policy, here is new information backing up this statement: Removing code based sandbox solutions in SharePoint Online

What you should do is to convert your sandboxed solution to an add-in, most likely a provider-hosted add-in.


As per the Microsoft, as shown in the Admin > Service Health currently SharePoint Online service is degraded. Next Update from Microsoft will be on Monday, August 1, 2016, at 8:00 PM UTC.

Check the service health.
