That folder which is now grey and italised has been given a 'no-select' flag. It means that greyed folder can contain other folders which contain emails, but it cannot contain any emails itself.

Is this a gmail account ?

If this is a gmail account:

• please logon to gmail webmail account via a browser
• select 'Settings'
• select 'See all settings'
• Select 'labels'

scroll down to the section which shows all the 'labels' you have created. Lets say you have a top level folder called 'Clients' which is greyed out and it contains a folder called 'Bob' which looks normal. Do you have something like this: [Gmail]/Clients > Bob then: both Clients and Bob will be normal (selectable) folders In imap like this: Clients > Bob

But if you have this: [Gmail]/Clients > [Clients]/Bob

Then in imap you will see this: Clients > [Clients] - this shows as italic font and greyed. > > Bob

Can you post an image which shows what you see in webmail for all those folders you created. Also post an image showing the fodler Pane, so I can see which folder is effected and compare to what you have in gmail webmail.

This is NOT a gmail account. It is a local web mail service with Thunderbird overlayed.

I can create a subfolder and it appears normal to start. If I move emails, either read or not to the folder, then later it will become italisized and greyed out. Sometimes it will still contain the moved emails and sometime they are all missing.

This has only started within the last 6 months. Prior, it never happened.

Any additional help would be appreciated.
