Mailflow Configuration Fails repeatedly

Hello CCal ,

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 Raphael Alganes , 

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.

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.

You should be able to open a support ticket here: https://support.sophos.com/support/s/?language=en_US#t=AllTab&sort=relevancy 

Kindly share with us the caseID once you have it. 

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

Hi Raphael Alganes ,

Thanks for the link! I opened a support ticket and the caseID is 07081543

Hello CCal ,

Thanks for taking the time to share the caseID, I have referred this Community thread and left case notes. Also, case has been already assigned to an engineer to be further investigated. 

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

Update:

This is now solved.

The solution was to contact the Email Team and give them explicit consent to do something with my domain, that ultimately allows me to see a "delete" icon so that I can delete my domain and start from scratch.

CCal probably too late now, but avoid Mailflow mode at all costs. So many issues (mainly because of MS). Gateway mode a much better option.
