I have been using eM Client for many years am currently using version 9.2. About 10 days ago I started getting error messages to the effect that eM-C could not connect to one of my four email addresses ie. Virginmedia. It was fine with the other three.
The current error message reads “5.7.8 Authentication Credentials Invalid (VM300)”. I have checked the relevant password and in fact now changed that both with Virgin and with eM-C and checked the port numbers but the error message keeps on occurring. Needless to say, I can neither send nor receive Virgin emails through eM-C. I can however open the Virgin web site and using the new password send and receive emails from there. This would suggest that there is no problem with Virgin just with the contact between them and eM-C.
This just happened out of the blue. Unfortunately, my virgin email address is the default with eM-C so this is causing quite a nuisance.
Really grateful for any suggestions - many thanks

According to the Virginmedia website that errors “5.7.8 Authentication Credentials Invalid (VM300) means your current “generated app password” is no longer working, and you need to revoke / delete that prev app password in your Virginmedia account online and generate a new app password and then go back to “Menu / Accounts” and change the password & save settings.
If deleting and re-creating a new app password online still is giving you that error and its an IMAP, Exchange, Office 365 type account, then i would suggest to remove and re-add your account via “Menu / Accounts” using the automatic account wizard with the new app password.
If removing and re-adding your Virginmedia account still has the same error, then go back to “Menu / Accounts” and update what your Virginmedia “Server address, Server Port and Security Policy” is for you incoming and outgoing tabs, so we can then see if there is any obvious error.
Many thanks for the reply and advice cyberzork. Thanks for explaining the error code that I have been receiving . I have tried to follow the logic in your details and the link to setting up a new password. Unfortunately my system is not showing the headings listed in the link nor the necessary items to open, correct and display. I do not remember ever setting up a ‘generated new app password’ and cannot find any opportunity to do that now. I seem to be going round in totally unnecessary circles with various Virgin web pages.
Oh for the good old days ( a few years ago) when I could devise an email address, create a password for that address and give both to an email client who would then simply collect my emails for me.
As I said, I can get into my Virgin emails on line and from there I have instructed that a copy be forwarded to another of my email addresses that I can access via eM- Client. In due course, I will instruct all of my Virgin email addressees to use a different (and accessible) email and kick Virgin into a well deserved touch.
Apologies for the rant and again thanks for your efforts to help
A very happy New Year to you
Then you may have previously “never had an app password” and its now required. So suggest if you carn’t find where to do that in your Virgin media account or webmail etc, then contact Virgin Media Technical Support via phone or webmail or community website for assistance.
I did not appreciate the new requirement and that may well be the cause of my problem.
Again thanks for the advice
