We will recommend first setup a Gmail Email Id first and check if it is working for you or not.

Then try with a custom email server email Id imap_open issue generally comes due to

- Your credentials not correct.

- Not sufficient permission provided for reading emails.

- Some authentication failure due to any certificate check.

For Gmail Do below things first:

Enable less secure app for gmail: https://myaccount.google.com/lesssecureapps

Please enable this also: https://accounts.google.com/b/0/DisplayUnlockCaptcha

Locate path on your project.
vendor/uvdesk/mailbox-component/Console/RefreshMailboxCommand.php

open file and add below line there.

Check in screenshot to add a line of code here: https://prnt.sc/w5bc5u

Add this line for gmail:
$server_host = "{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX";
