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.Anonymous commented
Might I suggest:
- Make it a feature that can be toggled on/off
- Default it to on for new tenants
- Give an error when trying to enable on existing tenants that contain objects that have email addresses that contain the + character
- Error login in Azure AD Connect when syncing objects from AD on-premises that contain the + character
