Question

I cannot create an IMAP account after I have changed mail provider

Tom Persson 0

I have used NewOutlook for some time (due to copilot) for both my office account (M365) and my private email hoste by a local danish webmail provider

A couple of moth ago i change email provider from one.com dandomain.dk.

And now i cannot create the IMAP account for my private email in NewOutlook. It works perfectly in the classic outlook with the server settings from my new email provider.

When I try to manually setup the IMAP account, it suggests the server settings from my old email provider.
When i overwrite the old server settings with the new settings and creatye the IMAP account it fails every time with:

"Something went wrong. You may need an app password"

Any Suggestions ? I have tried the dele the account, repair, remove chached credentiaslt .... but it keeps failing

But the problem with this account in New Outlook for Windows just started now?

There may still be something in the New Outlook for Windows cache. Just removing and re-adding the account doesn't clear everything.

There is also a known bug with an email address that is moved to a new hosting company, but retains the old domain, but that doesn't sound like your problem. Please advise if it is.

Hi Hornblower

The problem started in the moment where my new email provider were active, and i have not been able to create My IMAP account since then. Now I have to switch back to the Classic view for reading my private email (or read it in my iPhone).

I have tried to delete the account in the Classic view and recreate it, I have made a repair, i have deleted all windows credentials related to Microsoft in the credential manager - But problem remains. I have tried to raise 3 support requests, and spend over two hours on the phone with support agents from Microsoft, who gives up, and claims it is server side problems with my new email provider - but why do it then work with the classic outlook.

It more likes exactly as the last option, as new outlook keeps suggesting the old domain settings when i try to create the Imap account and ignore the the new settings i enter.

I have also noted that New outlook apprantely has created a "work or School" account when it uses the microsoft cloud to syncronise the IMAP emails. I don not have a subsriction for my private email, nor have i created it my self

All of that sounds like Classic Outlook fixes. I thought Classic Outlook was OK. That the problem is New Outlook for Windows?

Including giving it a bogus user/domain to start with so that you have complete control over the server settings?
