Versioning/Set the major version limit for all the lists and libraries (data loss involved)/Set-VersionLimit.ps1

+A short script that sets the major version limit for all the libraries and lists in the whole site collection or in the whole tenant.
+
+It requires SharePoint Online Management Shell and SharePoint SDK installed:
+
+http://technet.microsoft.com/en-us/library/fp161372(v=office.15).aspx
+
+http://www.microsoft.com/en-us/download/details.aspx?id=30722
+
+ 
+
+It uses recurrence to find all sites in all site collections and then goes through all the lists.
+
+If the list doesn't have versioning enabled, modifying the major version limit is not possible and you will receive the following error message:
+
+Exception calling "ExecuteQuery" with "0" argument(s): "Specified method is not supported."For some lists, enabling version may not be possible and you will receive a notification of that.
+
+At the end, a csv file is generated with the lists' urls and the status whether the setting was successful or not.
+
+ 
+
+As the script runs you will see green lists' titles for which the setting succeeded and red for those which failed:
