Sorry this is kinda long, but I wanted to include all relevant information.
UPDATE: See my reply to this post. Google has changed the logon protocol for 3rd-Party email clients to DISALLOW logging on with just user name and password, instead requiring support for OAuth. I’m not sure why two of my gmail accounts work in eMClient, while the third one does not.
I have three email accounts set up in eMClient. All three are gmail accounts. All three are IMAP/SMTP. However, only two of them have an “@gmail.com” domain name. The third one is a private domain name HOSTED BY GOOGLE, set up by my brother, which I’ve been using for years. Suddenly, I cannot log in to this account from eMClient.
Instead, I get an error message saying "Server says “Invalid credentials (Failure)”.
I have entered the correct User name (email address) and Password, but there seems to be nothing I can do to get it to log in.
I have checked using the Gmail Web portal in Chrome, and can still log in with the same user name and password. What’s more, I can still log in to the account with the email client on my Android phone, and it is keeping my Inbox updated.
I tried: Click “Accounts” on the eMClient main menu.
Clicked the name of the account ([email protected])
Clicked the IMAP tab. I tried using the radio button for “Use identity credentials” No joy.
I tried the radio button for “Use these credentials” and manually entered the User Name
and password. No joy.
I did the same on the SMTP tab.
I clicked the “Diagnostics” tab.
It says: IMAP: “?” (Question Mark) Unknown
It says SMTP: " " " "
There’s a button that says: “Fix”. It then tries a number of imap logon addresses, including a couple that actually look like they might be correct, using Port 993, as well as 143. But it never succeeds in logging on.
It comes back with a message: Server (__Link to Server Name) requires authentication. Do you want to send your credentials?
I then select the tic box for “Do the same for the rest of the discovery”, and click “Yes”
I clicked the "Enable diagnostics logs for: and checked the tick boxes for IMAP and SMTP.
Then, I clicked “Diagnose”
Then I entered the User Name & PW for the account.
It then says “Testing” with a progress icon.
Eventually, it comes back and says:
“Autoconfigure failed. An email server was detected, however, your credentials were rejected”
“Do you want to try again using a different password or username”
It doesn’t matter what I do. It won’t log me in.
I can also click the “Diagnose” button, but the results are the same.
This is alll I can do
Please help!!
