The customer has a number of Word templates and a PowerPoint template that they would like to import into Office 365.  A network share was created and the templates were copied to it.  A group policy was created under  User Configuration > Policies > Administrative Templates > Microsoft Office 2013 > Shared Paths where the Enterprise template path setting was set to the UNC path to the network share.  When Word 365 is opened, the templates do not appear. I also copied the templates to the %APPDATA%\Microsoft\Templates directory under the user profile for a test account.  I opened Word 365 and navigated to File > Options.  On the Word Options dialog box, I selected Save and set the default personal templates location setting to the %APPDATA%\Microsoft\Templates directory.  Unfortunately, when I open Word 365, the templates do not appear.

Hi,

As far as I know, we can add a network location to "Default personal template location" option, and then the custom template will appear in Personal tab. See image below:

Hope it's helpful.

This is what worked for me:

Enable the Personal templates path for Word setting under Microsoft Word 2013 > Miscellaneous and set the UNC path to the share where the templates exist

Enable the Personal templates path for PowerPoint setting under Microsoft PowerPoint 2013 > Miscellaneous and set the UNC path to the share where the templates exist
