I created a shared mailbox in Office 365 Small Business called "Maintenance." We are funneling inbound tasks for maintenance to complete to the tasks list in this mailbox. Everyone is using Outlook 2010/13. I don't want 2 of the 6 people to be able to delete the tasks. It would be nice if everyone can only delete tasks they created.
I have SharePoint Online and Exchange Online in my O365 Small Biz package. I demoed E3 and it had WAAAAY more granularity in the settings. I can't even use PowerShell with O365 Small Biz.
What is the best way to share common task lists while restricting who can delete the tasks?
