Mailflow Configuration Fails repeatedly

CCal

Hi, 

We're trying out the Email Protection from Sophos to see if it is any good for us, especially the VIP users and Clawback features.

We managed to configure this for the first time, and it was working for a week or so.
During initial config, we specifically configured it to a M365 Group, so we can test it on a few users.

However this week, we noticed that other users are also being added to the Mailbox list , meaning extra licenses were automatically allocated.
These users are not in the designated group.

I tried changing the domain settings in Sophois, but it keeps failing. So I decided to remove everything according to this article.:Reverse Microsoft 365 changes - Sophos Central Admin
Basically, deleting the Azure App, transport rules and connectors related to Sophos.

I waited a day before trying to re-configure, but this time the connection fails repeatedly.
Giving me this "Mailflow Rules not configured, Please try again"

I am global admin and I can see that a new App registration is made on Azure, but no new rules nor connectors.

The setup usually fails at ~50%

    Hello  ,

    Thanks for reaching out Sophos Community.

    Kindly check troubleshooting steps for Mailflow on this doc guide: https://doc.sophos.com/central/customer/help/en-us/ManageYourProducts/EmailSecurity/SophosMailflow/M365TestTroubleshoot/index.html

    Further, may we confirm if this is a trial? If this is, I may also suggest reaching out to your local Sales Engineer / Sophos Partner to have you assisted further on your concerns on this trial period. 

    Many thanks for your time and patience and thank you for choosing Sophos.

    Cheers,

    Hi  , 

    Thanks for your reply.

    This is not a trial, as my Sophos partner told us it's not possible. So we decided to just get a few licenses and try.
    We are trying to understand all these services ourselves, so we prefer to solve this using our own means.

    I read through the page you linked, but i am still unable to reconnect. I also read that Mailfow Tamper page.

    " If the test still fails, or you can't reconnect, you can manually disconnect then reconnect the domain. "

    According to the above line mentioned in the page, I should be able to manually disconnect the domain, but I do not see that option at all.
    (hovering my mouse over all the fields, does not give me extra options.)

    Hello,

    Thanks for the additional details. There should be a connect/disconnect option on Mailflow connection tab when you hover into the right side of the connection status then login to M365 should pop up on another tab. 

    Could you try to disable if there's any pop-up blocker on your browser and if it's possible to try it on a new tab / private or incognito mode?

    If none of the steps above works, I may recommend you to open a support ticket for this to be further investigated then kindly share with us the caseID once you have it. 

    Many thanks for your time and patience and thank you for choosing Sophos.

    Regards,

    Hi, 

    There is only a "reconnect" button, but that leads me to the same error again. Both with the edit mode on and off. See below.

    Sadly, nothing worked, I tried with Incognito mode and disabled all extensions. Also tried with uBlock Origin disabled.

    Alas, I cannot open a support ticket...

    It seems I have to contact our external Sophos partner after all.
