Hi there Errolandot.

we have received your mail. we are going to try to help you.

greetings Firefox Volunteer.

Hello Errorlandot.

did you have Thunderbird set to only display unread messages for the account perhaps. That is a very common cause of folks thinking mail is not being displayed.

Maybe that is because you see the message? Do you still see it after you last viewed your Thunderbird program?

Hello There again.

It is also useful to check this next to see if it changes slightly.

on the right of the screen, above the up down scroll bar is a squarish icon click it and select "reset columns to default"

Further solutions could be that there is an antivirus program running on your computer machine that could automatically lock your inbox.

Such problems also arise from this antivirus programs repeatedly.

Let me hear from you. Greetings Firefox Volunteer.
