Group emails have stopped sending

That´s exactly what happens to me since some time ago. I have several groups and randomly 1 or 2 stop working for days, then work again but fail another. I cannot see contacts inside the group. It is really annoying.

Alternativs to Outlook Groups

I'm nearing the point of giving up on Outlook Groups. I am the admin for a really small group of the Committee managing our apatment building (8 people, including me) plus a coupld of trusted senders. We essentially use it as a simple multi-sender email distribution list, and has worked well up until a few weeks ago. Now we have one problem after another, with bounces messages, obscure error messages etc. I've just about had enough.

What are the best alterantives (free or low cost)?

I'd like it to fucntion as follows:

• Members (set up by me): Receive all emails sent through the list. Can send to all members by sending an email to a single address ( e.g. ******@ourmailsystem.com)

Non-members: can send to all members via the single address ******@ourmailsystem.com. Do not receive messages sent through the list.

In other words, there are no 'trusted senders' - everyone is a trusted sender

I realise that there may be spam concerns with this, but the address would not be publicised anywhere so I don't think it woule be a problem.

If this 'open' sender option is not available in commercially run groups (as it isn't in Outlook Groups) then ther 'trusted senders' option would be a fallback.

Note: even though I have used the example domain "ourmailsystem.com" I don't mean to suggest that we would necessarily use a custom domain - the preference is for a pre-existing system and domain, as per some of the examples below.

Initial ideas:

Groups.io - setup/admin looks quite lcomples, and I don't t think the Admin can add members directly in the free version

Groups.google.com

Gmail.com with 8 simultenaeous forwarding 'rules' directing to the 8 members

Custom domain: we do actually have a custom domain (the building name) but we don't have a website yet or the time to commission the creation of one (not a priority hen there are other major maintenance projects going on). But I am interested to know there is a relatively simple and easy way to set up a mail distribution list without it costing too much in hosting etc and taking too much time. As mentioned above, intuitively I feel that a pre-existing mail system would be better. Come back, Yahoo Groups!

All thougts and suggestions welcome.

Thanks

I’m starting to think the best way forward is gmail. This has become ridiculous.

Hello

After not working for a number weeks, our little group mailing list sotarted working again... and then, about a week ago (I think) it stopped again.

The address I am sending to is in the format: <GroupName>@groups.outlook.com

My email address is registered as being a member of the group, but when I send a test message I get a "postmaster" bounceback with the text shown below.

What on earth is this about?

Our group has only 8 members, plus two trusted senders. All members are using standard email addresses, domains (GMail, Hotmail, Yahoo etc.) The two trusted senders are using a company domain, but they are not recipients of messages via this group, so I don't think that can be the cause.

Any ideas or suggestions gratefully received.

Delivery has failed to these recipients or groups:

mts<*****>@mts.outlook.comYour message couldn't be delivered. The Domain Name System (DNS) reported that the recipient's domain does not exist.

Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their domain isn't properly registered at their domain registrar. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.

There is also some diagnostic info further on in the postmaster bounceback message:
