SharePoint Online Today and SandboxedSolution.wsp

Occasional Contributor

In that past, we have shared site templates with other organizations as wsps and this has worked fine with SharePoint Online until recently.

It seems that new O365 Tenents have a communications site provisioned at the root instead of the Team site. This appears to mean that the Web Designer Galleries list on such a site collection only has two items instead of the usual eight.




However, we can still navigate to the solution gallery here by going to


When we try to upload a solution here we get the below message.



Does anyone have any suggestions as to how we can use sandboxed solution in SharePoint Online? 

It doesn't even seem to be possible to save a site as a template when a communications site is the root site, even though SharePoint Server Publishing is not active on the Site Features page.

Do just have to give up the ghost here?

Sandboxed solutions are deprecated and you should avoid them. To "emulate" the save as template feature, take a look at PnP Templates and also Site Scripts + Site Designs

@Juan Carlos González Martín does this still apply to no code sandbox solutions? 

No code sandbox solutions should work, but again if you are thinking on the save as template feature you have to go for the options I have explained
