Hello there We have read the question We try to help

you might had a update recent , and there where some symptoms after the download and installing of it ,it sounds logical. The inbox stays empty or getting blank suddenly? The complete situation had different issues at one time  ? The complete system was frozen suddenly? You did use the refresh method for the inbox service but I did not work? Can jou tell?

Other ways for having a empty inbox is to use very heavy anti virus software and the scan service for the inbox is used on the messages. try to turn that scan option off if that is possible.

Hello there

You should have used filters for Thunderbird usage to block messages or other to receive the inbox.You can search for these filters and delete them.

Other options are that the usage of Thunderbird with in combination of other email accounts are limited in receiving emails when using them both cause can be that the limit of one account is reached.

Hello there

If options are there to check if the isp service has some technical troubles with Thunderbird you can it try to search for it and solve it

Try to reach out for the account online and log in and and search for new inbox messages . If the account is accessible in the normal way of approaching then the configuration is changed or mis infilled it need to be corrected or changed.
