How to enable "Chat History Save" function by edit registry？

Question

Same as the title, I could not save chat history in Skype for Business, and find no relevant setting of options to enable this function. So maybe editing registry may help with this issue.

If the checkbox Save IM conversations in my email Conversation History folder is greyed out, perform the following steps:

• Open regedit: to do so, click the Start button and then in the Start Menu, either in the Run box or in the Search box, type regedit and press Enter.
• Create the registry backup. Note: you can skip this step, however, we highly recommend to back up the registry before you proceed to modifying its entries.
• Navigate to HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Office\x.0\Lync (x.0 corresponds to the Office version: 16.0 = Office 2016, 15.0 = Office 2013, 14.0 = Office 2010)
• Remove a DWORD entry named IMAutoArchivingPolicy. Note: If IMAutoArchivingPolicy has value of 0 the box will be unchecked and greyed out. If IMAutoArchivingPolicy has value of 1, the box will be checked and greyed out.
• Reboot your machine. After a reboot you should be able to check the box Save IM conversations in my email Conversation History folder.
