Security issues with sharing documents with OneDrive thru Outlook

Hi!

We have changed the default settings of sharing document thru OneDrive on Tenant Level to: Selected People and Read as default for sharing in OneDrive. In most clients the settings are honored but in the following it is not:

Office Pro Plus - Selected People with edit access

Outlook 2016 - Company wide with edit access

OWA - Selected people with edit access

This is so confusing but worst of all is that if you share thru OWA it Always sends out a link that works for the whole Company. Ie even if we do not change the Tenant settings to selected people/read the users who manually needs to restrict access to only selected people Think that they have done that but in reality they have send out a Company wide acces link

This must be a Security issue??

Please advise!

Thanks! //Magnus
