Outlook keeps replacing new server settings with old ones

[robertdh]

Hi,

Why is it always such a hassle if an outlook account setting needs to be changed?

I want to change the outgoing- and incoming mail server addresses from, let's say, mail.domain01.com to mail.domain02.com.

So I click "repair", select manual repair, click "repair" again, change the mail server addresses from mail.domain01.com to mail.domain02.com, click "Next" and I get "Account successfully repaired" I click "Done"

But, since it's outlook and that action didn't take half a day and it didn't involve any googling I get  suspicious...

So I check the settings I just changed, only to find that this seemingly easy change will probably take half a day after all.

Both server addresses had changed back to mail.domain01.com.

Anyone know which reg key to change this time?

Cheers,

Robert.

That's probably just autodiscover kicking in, have you updated the corresponding settings on the server side?

Hi Vasil,
thanks for helping!
I cant change anything on the server side, mail.domain01.com relays to mail.domain02.com but when I use mail.domain01.com I seem to get certificate errors so I want to use mail.domain02.com directly.
But since my email adrress is robert@domain01.com thinks go wrong.
Any way to turn of this auto discover?

Cheers,
Robert.

I think I figured it out.

I created the following key:

HKEY_CURRENT_USER\​SOFTWARE\​Microsoft\​Office\​16.0\​Outlook\​setup
DWORD: DisableOffice365SimplifiedAccountCreation
Value: 1 

 This brings back the normal email account settings form and changes made in this form seem to stick!

Thanks for pointing me in the right direction Vasil!

I'm having this issue too - since Friday, all 7 of my email accounts keep changing  from what I input to incorrect server information but, despite 4 hours of pro support with dell, it's not fixed yet.  @robertdh can you assist me in applying this key/I have no idea what to do with it.
