I was having an error during tranfer of my mail, and had to close my client Eudora Pro.
When I reopened it, one of my mailboxes complained like this :
Naturally, I tried the rebuild button :
But the next time I opend my client, the same warning showed up
as in the first picture.
So, trying to be smart, I choose door number 2, "Use Old"which gave me this warning :
Hmm, beeing on the safe side, I went for the safest option, "Rebuild" and it
gave me a familiar popup message, so far so good.
But, once again, after restarting the client, warning number 1 showed up.
So this time I ignored the message pushed "Use Old" and the second warning showed up,
beeing in a good mood, I said let's go for it, use the old one.
And what did I see ?
Well.. now I felt insulted, and choose cancel, I made a new mailbox, copied all the mails over to it,
then just deleted the one who kept on making fun of me
before I renamed he new one to use the old ones name ( due to automatic filtering of mails )
befre I rebooted my computer, restared the clent and opend the mailbox without any errors
