We announced at Ignite that we are actively working on bringing dynamic plus aliases to Office 365.
To get around existing usage, the plan is for an opt-in setting. Our ETA is to have this available for all customers by the third quarter of 2020.
I will keep you updated in Uservoice on our progress.Josh Davidson supported this idea ·Josh Davidson commented
As a developer we made heavy use of this feature in GSuite before moving over to O365. It allowed us to create disposable accounts for testing purposes. We're kind of stuck now with creating a bunch of manual of aliases.
