I'm trying to add GMAIL account A into GMAIL account B, using Chrome Browser, but I am getting this error





User ID and Password already confirmed correct, POP and IMAP setting all already enabled, and I have even enabled "Allow Less Secure" option in Google Security Settings, but still getting the same above error.

Does anyone encounter this before and perhaps have a solution for it?

error msg macam pop3 not yet allowed wo

Fix the "Server denied POP3 access" error message
If you use 2-Step Verification: Create an app password. <<<<<< also try
If you use a work or school account:
In the "POP Server" section:
Enter “mail.domain.com”.
Select Port 110.
If you use Google MX records with a work or school account:
In the "POP Server" section:
Enter “pop.gmail.com”.
Select Port 995.

Tried all the above already, still getting the same error. Apparently, this only happens on this one particular user account. I have already done like 7 user accounts so far, and none of them I encountered this. All can add account easily, except for this particular user. No 2FA is set, never enable this function before. All these accounts are under one same company domain. Very strange. I use "Port 995" and "pop.gmail.com" for all those that I have done, all can add and work fine, until this one particular user account. I suspect at the backend admin control panel some security setting must have been enabled by accident for just this one particular user, and problem is I don't know where to look. When all other users can work, except for one fellow, this must be the cause.

Out of curiosity, I try setting this problematic account using MS OUTLOOK, and it can be added easily, but through IMAP auto kind of setting though, not POP.
