Hi all,

This weekend I've migrated my email from GSuite to Office 365 (or Microsoft 365 shortly), so far so good.

I setup a catch-all across the domains I have, so any emails sent to xxxx@domain.com will get dumped in my primary inbox.
I use this so I can set a custom email address for nearly every service, such as geekzone@domain.com, facebook@domain.com etc, that way if one service leaks the email (as has happened a few times now) I can simply block emails sent to that account and move on.
This worked great in GSuite and appears to work the same in O365 as well.

In GSuite I had setup some of my commonly used ones as an alias, such as web@domain.com, which allows me to then send from that email address.
I can setup the same in O365, but I've noticed I also have an option to enter an email address in the From field as well as select one from a list.
I've tried entering a non-alias address into this field but it fails saying I don't have permission to send from that account.

Basically what I'm trying to achieve is a way to send from any email address on my domain, even ones not setup as a mailbox/distribution list/alias.
Does anyone know if this is possible/how to achieve this?
I'm only using the Business Essentials plan as I don't require the desktop apps, so ideally I'd want to be able to achieve this using webmail only.

Cheers!

Yeah, I found this option very deceiving initially. Now, it seems to me to be a drop down list that you can search for any email addresses that you are allowed to send from. Not a field that you can make up an email address on the fly. I hope somebody can answer your question because they will answer it for me as well.

BTW How did you migrate across?

Who / how did you update your DNS entries?
Who / how did you migrate your email? I found cloudm.co for my migration & it was actually quite easy, but I can't say 100% if all my group data was migrated.
What was the motivating factor to move? NZ$ 91.20 for O365 certain is cheaper than NZ$ 230+ for GSuite

Just be aware that if there is a mismatch between the actual and stated sender addresses, your emails will often get rejected as spam

+1 would also like a solution to this.

I'm a geek, a gamer, a dad, a Quic user, and an IT Professional. I have a full rack home lab, size 15 feet, an epic beard and Asperger's. I'm a bit of a Cypherpunk, who believes information wants to be free and the Net interprets censorship as damage and routes around it. If you use my Quic signup you can also use the code R570394EKGIZ8 for free setup. Opinions are my own and not the views of my employer.

1. My DNS is run through CloudFlare, it took minutes to update during the initial account setup for my primary domain, and a few minutes later on to add the others.

2. I followed this guide to migrate the emails over using just an IMAP migration. There is another method for Gsuite which involves setting up a service account, and I think this can enable migration of contacts and calendar entries, but I want to do a big cleanup so will do those manually. And as it's only the one account being migrated, it doesn't save me much time since I don't have hundreds of accounts to setup as well.

I'm not 100% sure if all date has come across so that's a bit of a concern, so what I'm planning to do after is do a full account export from GSuite prior to deletion, so if anything is missing I have a backup I can grab it out of later on.

3. Motivating factor was mostly cost. GSuite was running around $12NZ/Month including GST, O365 is around $8.80NZ/Month including GST. At the moment they have an offer where the first 6 months are free so that sold it for me. While it's only a small saving in the grand scheme of things, I personally don't see any benefit in paying that extra few dollars a month to Google. If it had some killer feature I'd probably stay but it's not worth it at the moment. GSuite also only provides 30GB of storage (including mail), where as O365 is 1TB.

Hadn't actually considered this. Though in the past with GSuite when sending as an alias I hadn't noticed any issues. Not sure if O365 would behave any differently, or perhaps I got lucky and none of my emails got marked as spam when doing this. There's probably no easy way around this other than setting up shared mailboxes/new users for each email address I send from, so that the email is the same for actual and stated address (Which I'd very much like to avoid as that'd be way too annoying).

As far as I'm aware, it's down to the receiving system so sometimes they'll get through, other times not.

Bumping incase someone may see this.

Still looking online but nothing I've found so far, may not be as easy as once thought and probably as suggested it's just a list of emails you can send from with a search field for that list at the top.

To send from another mailbox or distribution list, you need to ensure you have "Send As" permissions.

For a group:

Go to the Exchange Admin Center » recipients » "groups" tab.
Double click the group
Go to "group delegation" and add your account into the "Send As"
Click Save.

I haven't found a way to deal with aliases. (Work around is to change the alias into a distribution list)

Within the webmail (assuming the "full experience" not the light version):

Start a new message
Click the ellipse (next to discard)
Click "Show From"
Click the "From" button, if the email address isn't in the drop down, select "Other email address..." and type in the email address

Hope that helps

Thanks Wazzageek - Sounds like my hopes were too high! Was hoping to avoid having to individually create each email (As a group/alias/shared mailbox) that I'd send from.

I don't do it an awful lot so I'll bite the bullet and just setup a shared mailbox as/when I need to send from a specific account, and just set rules to auto-forward replies back to my mail account.

Side note: I get to re-create my account because I'd added an extra character in the "company name" field during setup.
That's now propagated everywhere as my Tenant Name, including to Sharepoint and OneDrive, and it's impossible to rename currently (https://office365.uservoice.com/forums/273493-office-365-admin/suggestions/10285887-make-is-possible-to-change-tenant-name-in-office36)
Don't make the same mistake!

Cheers all!

Word of warning - if you remove the Exchange license from your user account, you will loose the aliases created. (I recently changed my licensing so that I could get a 1TB OneDrive ... and chose the wrong thing ...)

At least in O365 it is a lot easier to update the global / company wide address book. In G Suite, you can only do it via an API. 🤬
