Hi @Mikhail Firsov ,

According to my test, please run below commands to allow external IMAP4 server settings to be viewed by end users.

Set-ImapSettings -ExternalConnectionSettings {Servername.Contoso.com:993:SSL}  

To apply these changes, you must restart IIS. Run powershell as administrator to run below command.

iisreset

Oh, sorry - I was accessing server2 while configuring IMAP seeting on server 1 (due to the dns round-robin) - it does work, thank you!
