When I was migrating from Windows 7 to Ubuntu, I took my Thunderbird profile and copied it into the Thunderbird profile folder under Ubuntu. When I started Thunderbird, everything worked fine and all emails of my three email accounts could be displayed. But there occured an error with just one email account that did not affect the other two: I could not read my emails that were saved in its
Now, I am able to see the list of all emails in the
Inbox folder but I cannot open them. When I try to open a message, a blank page appears. Strangely enough, however, the content of these emails that cannot be displayed is still shown when I am using Thunderbird’s search functionality. Moving the emails in the
Inbox folder to another folder does not help. If I do that, they are still not displayed when I click on them.
I do not know why this just happened to one out of my three accounts and why all the emails in its
Inbox folder are affected but not the other ones that reside in other folders.
What might be the problem and how can it be fixed?
