My wife and I have been using Thunderbird for many years through various incarnations of Windows. We upgraded recently to Windows 11 and are running v.102 of Thunderbird. When my wife tried to open her inbox this morning there was a continual buffer eventually disclosing an empty panel except for a column of stars all down the left side. Buffer is still running afte some hours. I checked the properties of her inbox. Folder location line is blank. Number of messages unknown. I can identify the folder as it is identical to mine except for one digit but I am unable to paste or type this location into the blank line. So, I can't repair the folder. Her sent folder is fine and all my folders working perfectly. Any idea how I can get Thunderbird to recognise her inbox, please?
