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.Ruben SAADA supported this idea ·Ruben SAADA commented
I found a manual solution while waiting for Microsoft to develop the functionality.
You can create a mail flow rule in Exchange with the following options:
If the message ...
the recipient address matches these templates: "^mailnickname\+"
Perform the following operations ...
Redirect the message to "email@example.com"
Received from "Inside the Organization"
The last option is very important because if you do not put it you risk losing emails.
So you will enjoy the same functionality as Gmail except internally.
(The allias + feature will only work if the sender is not part of the company's Microsoft tenant - normally this is not a problem for most of us)
Make me your returns if it suits you!
