Why is it that after I delete my e-mails the next time I log on they are all back? Sometimes as many as the last fourty or fifty show up again.

This has only occurred since the last update. I delete my e-mails. The next time I log on all the e-mails I had deleted the last time are all back in the inbox. I then have to delete them all a second time before they are gone for good. This is very annoying since it can often be as many as fifty or sixty e-mails at a time. How can I fix this?

Are you talking about the Inbox?

deleted emails can reappear where a folder may have some corruption. This is usually due to keeping too many emails in the Inbox and not compacting on a regular basis.


Make a copy of any emails in that folder which you do not want to lose; perhaps store them in Local Folders. then delete the emails. then compact the folder. - right click on folder and select 'Compact'. If you lost any emails due to compacting, then do not worry because you saved a copy of the ones you wanted to keep in Local folders, so you can move them back.

Select the 'Deleted' folder, right click on folder and choose to 'Empty Deleted'. then right click on Deleted folder and select 'Compact'.

Emails should now be deleted.


Note: the Inbox should be used as an Inbox and not a general storage. Please read helpful information on how to maintain a healthy Thunderbird and also read information on compacting, what it does and why it is important. http://kb.mozillazine.org/Keep_it_working_-_Thunderbird
