I’m having a hard time getting SMTP to work with my Office 365 account I keep getting a error that says
“SMTP Is marked as readonly” So far no help from support.
Ideas? I’ve already posted this topic on the facebook group

I am having the same issue.
We are having the same issue here.
I was able to get it working by using smtp2go.

SMTP2GO is really good
+1 on SMTP2GO - free to start with, and well worth the cost if you go over the free limit.
Works fine for us. We had no choice but use SMTP.
In newer 0365 tenants smtp auth is turned off by default. go to user, mail tab, then manage email and turn on smtp auth
I did that and still has a problem

Same issue. There was another thread at https://community.syncromsp.com/t/settingstore-smtp-is-marked-as-readonly/1148 but looks like Syncro deleted it? Are they censoring threads here now??
I was able to get this working. While not the ideal
The issue was due to Microsoft Conditional access rules “Security Defaults”
If you were to check in Azure AD under Users > Specific User > Signin Logs
you will prob find this error “Access has been blocked by Conditional Access policies. The access policy does not allow token issuance”
So I have disabled Security Defaults - Azure Active Directory security defaults | Microsoft Docs
Then created my own Conditional Access rules.
This is not the ideal, however it is a workable solution
@luckman212, I restored the topic.
Logs show I deleted it, but there’s nothing in the thread breaking the guidelines.
I apologize. The deletion wasn’t intentional.
Ah, yes great catch and makes 100% sense since the new default is to block smtp Auth ( legacy) with this said I wonder if Syncro is going to add modern authentication for byosmtp? . I know at some point Microsoft is going to disable it permanently.
I just went through this setup. Here are my notes for anyone else attempting to get a dedicated M365 mailbox setup with Syncro.
To use a Microsoft 365 email account ex. “helpdesk@mspname.com” for Syncro Tickets (inbound and outbound).
Login to your DNS provider for mspname.com
Microsoft 365 admin center - https://admin.microsoft.com/Adminportal/Home#/users
Microsoft 365 admin center - https://portal.office.com/Adminportal/Home/#/Contact
Exchange admin center - Sign in to your account
Microsoft 365 Defender - Sign in to your account
Just letting you know that I fixed this on my Office 365 account.
I had “Block legacy Authentication” set in my azure portal. Once removed, the SMTP worked correctly.
