In Office 365 site, to save customized site as template we can’t have save site as template option as we don’t even activate publishing feature. For example, I have created a site in office 365 environment and added some third party customized features like twitter and tried to save the site as template by navigating to Site settings. Bu I am unable to find “Save site as template” option in site settings page.
While troubleshooting the issue I have checked few posts in msdn and tech net forum. By checking all the posts I have found that SharePoint doesn't allow to save the third party apps. By removing the third party apps, i am able to save the site as template. But I need the third party app should be include in my sub site.
By checking few more posts I got a trick for this. To enable save site as a template in site settings page, we have to set “SaveSiteAsATemplateEnabled” parameter in office 365 site. To do that, open the site in SharePoint designer in homepage, click on “Site Options” link.
We can get a pop up box with four tabs. In Parameters tab, find for “SaveSiteAsATemplateEnabled” and update the value from false to true.
