I installed Thunderbird 0.8, migrating from Mozilla Mail. I have several accounts in MozMail, two of which have the same server name but different user names. In MozMail the two accounts are stored in two folders: mail.domain.com and mail.domain-1.com. Mozilla does this to differentiate of course. When I migrated to Thunderbird, I clicked on the account for UserName1 and saw the emails and folders I was expecting. When I clicked on the account for UserName2 I saw the *same* emails and folders as UserName1's account. When I made changes (labels, deletions, etc) to either account and looked in the other account, these changes were reflected there as well. I looked at the location of the local directory (in the server settings) for both accounts and found that they are both pointing to the same directory (mail.domain.com). I then manually looked in the mail directory and found no sign of the files for UserName2. I can only assume they either were never imported or were overwritten at some point.

I have a silmilar problem. I was using Thunderbird 0.8 , when importing from Mozilla 1.7.3, I had two accounts with the same server name, and eventually those two accounts were "merged" together. They shared the same mailboxes, because of , I guess, the same server names as the directory names.

can you e-mail me your prefs.js? thx...
