Thanks for your understanding.
We have a proxy and it causes a lot of issues we can't create a profile if we connect to the LAN and also outlook connect and disconnect
1.Did you mean if connecting directly without the proxy, Outlook can connect successfully?
2.Do you have an Exchange On-premises server in the LAN(proxy) network?
3.Does this proxy also proxy DNS requests?
If yes, can autodiscover.<your O365 domain>.com be resolved correctly to O365 servers on the DNS server in LAN?

2- Yes
3- I did not understandWe can't create a profile and also it shows basic authentication dialog box i have read a lot of article to change the registry but not working and once you write the username and password it will ask you again for user name and password the mailbox hosted in the cloud
Also sometimes once I add an exception in the proxy outlook.office365.com outlook work and sometimes for different devices not working and showing disconnect or trying to connect

Please also trying adding autodiscover.<your domain>.com to exception.
In this case, if your O365 domain is mail.domain.onmicrosoft.com, you may need to exclude autodiscover.mail.domain.onmicrosoft.com from the proxy and see if it can help with this issue. -
