I use Mozilla Thunderbird and have several addresses with one email provider

Friday afternoon, one of the emails, *****@tds.net stopped loading emails to the inbox. The other account work fine.

Hello, thank you for using Howly. I’ll be happy to help you out! May I ask your name?

Nice to meet you, *****!
So you are not receiving the emails on one of your email accounts in Thunderbird?


What do you mean by "not loading"?

Customer Replay

The emails are being received by the TDS portal but are not showing up in the account inbox after Friday at 3:10 PM

Got it.
Let's try to repair your inbox folder.
Open Thunderbird and select the folder in which the email is present which you want to view.
Next, right-click on the selected folder and choose the Properties option.
Now, you will see the Repair Folder button in the Folder Properties. Click on the Repair Folder > OK.
After the completion of the repair process, try to open and view the emails again.

Got it.
Let's Rebuild Folders in Mozilla Thunderbird.
Before implementing the steps, make sure that Thunderbird is closed and is not running in the background.
Here are the steps:

  1. Open the location similar to: C:Users<Username>AppDataRoaming
  2. Go to the data folder i.e., ImapMail or Mail folder as per your account configuration.
  3. If the problem is with your Inbox, carefully delete the Inbox.msf file.

I'm trying to find the Inbox.msf file

found it and deleted it

Got it.
Now, restart Thunderbird. It will rebuild the MSF file and show all the messages.

Customer Replay

I'll look again.

Did you close Thunderbird before deleting the file?

Customer Replay

I X'd the window.

Got it.
Did you terminate the background processes?

Customer Replay

not sure. I'll go to Task Manager and stop the pr ocess
OK it is not running in Task Manager. Should I open it again?

Hold on. Did you double-check that the needed file was removed?

Customer Replay


Ok. Please start Thunderbird and try checking your inbox.

Customer Replay

still no emails loading

Got it. Did you try removing the account and then adding it back?

Customer Replay

no Which account?

I'm sorry, I mean your email account on Thunderbird, on which you do not receive emails.
To delete an account, select it in the left pane of Account Settings, then Account Actions at the bottom of the left pane, Remove Account.

Customer Replay

It's gone

Please try adding the account again.

Customer Replay

I had to find the password

Do you need help resetting the password?

Customer Replay

No, I found the one it likes. It seems to be reloading the emails.

Ok. Keep me updated, please :)

Finally I have 39 unread messages. Thank you very much.
