Disable PST creation all office versions

[Eddie Sardinha]

Hello All, 

We're in the middle of migrating to office 365 and would like to disable PST's.  What is the best way to disable creation of new pst's across all versions of office?

I know there are registry keys we can add to GPO but is there a simpler way, just looking for options. 

Thanks,
