Hi there, After downloading and installing the new Thunderbird 102 onto my 64 bit PC, I am using imap, I have found that although all the email accounts appear there and many folders or sub folders missing. As well as the content of some folders that appear but are just empty. For example, on my main email they Inbox appears but is greyed out and shows none of my current emails but with the sub folders they are there and the emails are there. So: Account - me@mydomain.com Inbox - greyed out and no content Drafts - working fine Sent - working fine Spam - working fine Sub folder A - working fine Sub folder B - working fine It’s as if it just hasn’t subscribed to the Inbox. Although that doesn’t make sense if the sub folders are there… I can send emails fine. They appear with my footer that is set up in the account and they appear when I log into webmail and look in its inbox. I tried, using TB, to move an email into the inbox, to try and prompt the activation of the folder but as it is greyed out in the move function as well it cannot be done. I have looked at the account settings and cannot see an issue, it still has the imap address to get the emails. Second example Account - Me@mydomain.net No folders :( On several other accounts I can see the account but with no folders at all below them. When I installed it there was nothing else running, there were no issues displayed and it was, as with every other update of TB since I started using it back at the beginning, quite fast. I made no changes to settings after install as I wanted to look around and see what had changed. I did notice that despite it being an update and is used offline that it took quite sometime to download emails in several folders. I figured it being an update that it the locally stored msf(?) files that were already on my PC. This is really quite frustrating and disappointing as although I can use webmail it does not have as friendly user interface and accessibility as an email client and I do not use Micro$oft products. Is there anyone that can assist with this? Thanks for reading this and I will also thank anyone that can help. TeeKay
