As someone previously posted on this thread, different users are experiencing different problems. Four days ago, on Sunday evening, I was unable to connect to my VM webmail via MS Outlook 365. Outlook was reporting that my Email password was wrong (but it was obviously just relaying what VM webmail was reporting back to it).
This issue happens from time to time with VM Email and I always sit it out rather than try to change my Email password while VM Email is obviously down.
Frustrating, but I wasn't worried about my Emails as I use the POP3 interface, so had everything securely on my PC in *.PST files, which I regularly back up as a matter of routine.
Meanwhile, others on this thread were reporting all manner of other issues: some were reporting missing folders and Emails, while others were suddenly receiving the same Email twenty times.
I was able to logon to VM Email yesterday morning (Wednesday) and all my Emails and folders (at the VM webmail end) were intact. A few from early Wednesday morning had failed to drop into my MS Outlook Inbox but they were mostly junk anyway (Email from Facebook saying a lot has happened on Facebook since I last logged on etc.).
As I say, I wasn't particularly worried as I regularly backup my Outlook *.PST files, which contain all my Emails and folders going back to the 1990s. They are backed up to OneDrive, and a couple of locally attached hard disks.
As a POP3 user, I have never tried IMAP so don't understand why IMAP users can’t backup their own Emails and folders in a similar way. Or is that not possible with IMAP?
Using a computer without backups will always end in tears at some point.
