Clear cache for autodiscover endpoint acompli.net for domains

Question

Hello,

I am part of a hosting company, we are trying to troubleshoot an issue regarding auto configuration of Outlook when certain domains are used. We've seen similar forum posts like the situation we have, and have narrowed it down to Outlook using its own server to pull settings for the email account being configured (prod-global-autodetect.accompli.net).

We currently have two domains that has this issue, but it could potentially be more than just these two, as this issue was reported by the clients trying to use their mail service with their hosting.

Domains are turbologic.ro and yoursoftalternative.com

Recreating the issue is very simple, open an Outlook and try to configure an email for any of these two. When using turbologic.ro, if you use any@turbologic.ro in Outlook, it asks you to login to Gmail to sync/configure, but their email service is not with Gmail (autoconfiguration settings being pulled are not from the hosting server, but from prod-global-autodetect.accompli.net).

If you use any@yoursoftalternative.com, then the configuration pulls some imap.1und1.de which again is not the actual server settings (settings being pulled from prod-global-autodetect.accompli.net).

We confirmed this by using Fiddler and watching the requests being made to prod-global-autodetect.accompli.net, screenshot attached.

This can also be verified using curl from command line, like this:

curl "https://prod-global-autodetect.acompli.net/autodetect/detect?services=office365,outlook,yahoo,google,icloud&protocols=eas,imap,smtp,rest-cloud" -H "X-Email: any@turbologic.ro"

Reply was:

{"email":"any@turbologic.ro","services":[{"service":"google"}],"protocols":[{"protocol":"imap","hostname":"imap.gmail.com","port":993,"encryption":"ssl","username":"any@turbologic.ro","validated":false},{"protocol":"smtp","hostname":"smtp.gmail.com","port":465,"encryption":"ssl","username":"any@turbologic.ro","validated":false}]}

How can we clear or refresh the settings acompli.net offers? We do not have control over client devices to be able to fix it from their side.

Answer 1

It seems like the autodiscover service is caching incorrect information for your domains, which is causing Outlook to pull settings from an unintended source. Sometimes, clearing the DNS cache can resolve discrepancies related to domain resolution. This can be done on individual client machines or at the DNS server level, depending on your setup. Since the issue involves a service hosted by Microsoft (acompli.net), reaching out to Microsoft’s Answer Desk or support team could provide you with the necessary steps to clear or refresh the cached settings. As a temporary workaround, you can manually configure the email accounts in Outlook using the correct server settings provided by your hosting service.

Answer 2

That is what i am trying to do here, reach Microsoft to this.

Answer 3

The way i see this, there is no way of contacting Microsoft or whoever is in charge of that endpoint where Outlook client is doing the lookup...
