Are you using the latest 12.1.2 release?  If not I would update and see.  Also when you added the configuration was there a prompt for an SSL certificate and did you accept it?  Trying to find more details on this one.

Wow thanks for the quick response. This is a fresh install of the latest release so I am at the latest version. Because it is Microsoft 365 modern authentication there is no SSL cert setting to be found.

Ok.  I will do some searching as I have never seen this one before but don’t use M365 auth for email alerts as we have our own mail servers we use.

I use M365 auth and haven’t seen that error. I did a brief search and couldn’t find anything. May be best to open a Support case and see if they have a resolution for you.

Have you tried re-authorizing?  I’ve seen this when it’s not authorized, but usually the message shows that it’s not as well.  Will note that this is pre 12.1.2.

I tried reauhorizing twice and still no luck. I would just use SMTP but Microsoft shut down app specific passswords which eliminates the ability to config for that.

Would suggest contacting Support to see if there is a bug with this and they can check your logs.

Just brainstorming but any sort of SSL Interception or packet inspection happening on your firewalls?  Also, is the from address a valid email address in your M365 tenant that you’re relaying through?

@Chris.Childerhose I am on the community edition, how would I get support. I understand that I have to be a paying customer to do so.

You can still submit a support ticket but it will be a best effort support versus being on paid support.

Can you try something - if you have a Gmail account set up Google for the mail relay and see if that works?  I am just wondering if the issue is a license problem possibly.

I think you can no longer use Gmail (free) for relaying email and have to be a Workspace customer.  That said, there are some services out there that work for relaying that would have a free tier.  SendGrid is the first one that comes to mind.  Also, if you use a different service for messaging hygiene than the EOP built-into M365, you may be able to relay through that service instead with some light configuration.  For instance, I have clients using Barracuda Email Gateway Defense and we can relay on-prem through that service rather than direct to M365, though we almost always relay through 365.

Hi @mattymil -

Per the Veeam Edition Comparison Guide:
https://www.veeam.com/veeam_data_platform_feature_comparison_ds.pdf pg. 19,

“Email notification/customization capability is not an available feature in the Community Edition” sadly.
 

Only way to enable this feature is with a license.

Best.

Thanaks for this. I am not using Veeam One, I am using Backup and Replication 12 Community edition. I configured my 365 environment to accept SMTP AUTH and configured the email notifications using SMTP. THe notifications are now working.

Glad to hear you got it working @mattymil and thanks for sharing the solution.

Hi @mattymil -

Ah yes...that is in the VeeamONE section. Apologies for that. Good catch! 

That’s great to hear you’re now working with SMTP Auth through your M365 infrastructure. Thanks for sharing what you did to get that part working.
