Support for Dynamic '+' Email Aliases in Office 365
Hello,
I am familiar with using a plus sign following my email alias to create dynamic unique addresses for a Gmail account. e.g. test.email+signedup@gmail.com will arrive at my Gmail mailbox, where I can then apply rules based on the 'To:' address. See this page for details: https://support.google.com/mail/answer/22370
I tested this on my Office 365 address and it works, but only for email addresses in my parent domain. Using the aliases on subdomain addresses results in a 'recipient not found' NDR.
Does anyone out there have more information on this feature or if it even is one for 365 / Exchange?
Thanks!
Ryan

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.

This request is climbing the ladder. To help the MS folks understand this, here are some references for the functionality:
- Wikipedia SMTP Subaddressing: https://en.wikipedia.org/wiki/Email_address#Subaddressing
- RFC 5233: https://tools.ietf.org/html/rfc5233 -

Come on guys. I’m trying to sell this to 1000’s of google users and it all falls down here.

For people who don't understand this, it allows you to use versions of your email for specific things...
myuser+newsletters@mydomain.com
myuser+vendors@mydomain.com
myuser+bills@mydomain.comWhatever. If you're signing up for a conference, you could use..
myuser+conf20190111@mydomain.com
Then anytime you received an email at that address, you'd know exactly where it came from.
myuser+sketchvendor@mydomain.com
Now you know. It's great for testing, and all kinds of little things. This would be a great addition.

This would be great. I'm starting to use it more and more since I found out my GMail had it. I didn't even know that my Outlook.com email would work with it also.

A Ghacks article proves that this feature has been available on Outlook.com since 2013. Since Outlook.com has been using a version of Office 365 for a couple years now, how is it possible that full-blown Office 365 doesn't have this? It's a superset of Outlook.com! So it must have been a deliberate choice.

this is so frustrating. i'm guessing the o365 team doesn't understand how hard it is to pitch migration from gsuite when so many tools are relying on dynamic addresses for functionality.

This is a must have for us to support software development, testing, employee alpha and beta testing, and general good security practices. I would love to understand why it has not yet been prioritized and what may be blocking it.

Seems like '+' sub-addressing already works in our tenant for internal and external mail.
e.g. user+blah@domain.com is accepted to the user@domain.com mailbox (Outlook still shows user+blah@domain.com as the recipient address).

Not even "Thinking about it"? Bad form! Add this to the roadmap asap

+3 votes for this capability.
The workaround is to add the plus extension addresses *manually* in the exchange admin center and not in the general users panel for migration purposes but that's not really a great solution long-term.
Other MTAs have this feature, for example postfix... which calls it the recipient_delimiter. Would love to see that config in the exchange admin which would take care of this feature request nicely.

Can we please add this basic universal email functionality to microsoft?
some of our corporate system administration requires staff members to log into our admin tools with a different email for every tour/ group - and it will be a nightmare to have to create email addresses and alieses when with Google Suite we just +-ed aliases onto one email account -

A variation like this would be helpful user.ANYTEXT@domain.com. Reflexion has had this feature for years: https://community.sophos.com/products/reflexion/b/reflexion_news/posts/did-you-know-address-on-the-fly-aotf

I see that you can use a comment in parenthesis in the name part as it's already pointed earlier in the comments. I'll try later whether it's possible to get that comment back when receiving the email (I've tried it on my mobile device but Outlook app don't give me any tools for checking the original received email headers.

This works on my personal @outlook account, but not company office 365 account. What a mess.

Yes please! I am so used to this coming from Gmail that it's hard to not be dissapointed while looking for the same feature in Office 365.

Let's get this going! It is absurd this feature isn't in this suite yet.

anonymous said "WORKAROUND TODAY:"
I tried adding the rule as described. There's no "When recipient matches", but there is "If the message includes these words in the recipient's address." I added a rule based on that, but it doesn't work for me. Messages received for "addr+extra@domain.com" don't arrive. So much for a workaround.
