Mailbox​ ​Folders

On​ ​the​ ​left​ ​side,​ ​you​ ​will​ ​see​ ​a​ ​hierarchical​ ​list​ ​of​ ​all​ ​folders​ ​in​ ​your​ ​mailbox.​ ​Folders​ ​can​ ​be​ ​used​ ​to​ ​organize​ ​email​ ​messages​ ​by​ ​topic,​ ​sender,​ ​or​ ​any​ ​other​ ​criteria​ ​you​ ​choose.

Incoming​ ​messages​ ​usually​ ​appear​ ​in​ ​the​ ​Inbox​ ​folder,​ ​which​ ​is​ ​the​ ​first​ ​item​ ​in​ ​the​ ​folder​ ​list.​ ​There​ ​are​ ​special​ ​folders​ ​used​ ​by​ ​the​ ​system​ ​to​ ​store​ ​junk (Junk), sent​ ​(Sent)​ ​or​ ​deleted​ ​(Trash)​ ​messages,​ ​as​ ​well​ ​as​ ​saving​ ​drafts​ ​of​ ​unsent​ ​messages​ ​(Drafts).​ ​These​ ​system​ ​folders​ ​are​ ​indicated​ ​with​ ​special​ ​icons.

The​ ​number​ ​of​ ​unread​ ​messages​ ​in​ ​each​ ​folder​ ​is​ ​displayed​ ​at​ ​the​ ​right​ ​border​ ​of​ ​the​ ​folder​ ​list.

Clicking​ ​on​ ​a​ ​folder​ ​in​ ​the​ ​list​ ​will​ ​show​ ​the​ ​messages​ ​contained​ ​in​ ​that​ ​folder​ ​in​ ​the​ ​message​ ​list​ ​on​ ​the​ ​right.​ ​The​ ​currently​ ​selected​ ​folder​ ​will​ ​be​ ​highlighted​ ​in​ ​the​ ​list.

Folders​ ​with​ ​hidden​ ​subfolders​ ​are​ ​indicated​ ​with​ ​a​ ​small​ ​[>]​ ​icon,​ ​which​ ​can​ ​be​ ​clicked​ ​to​ ​expand​ ​or​ ​collapse​ ​the​ ​folder​ ​tree.

Folder​ ​Operations

In​ ​the​ header or ​footer​ ​of​ ​the​ ​folder​ ​list,​ ​clicking​ ​on​ ​the​ ​Folder​ ​actions​ ​icon​ ​will​ ​display​ ​a​ ​list​ ​of​ ​folder-related​ ​actions.​ ​Most​ ​of​ ​the​ ​actions​ ​in​ ​the​ ​menu​ ​affect​ ​the​ ​currently​ ​selected​ ​folder.

Compact

This​ ​action​ ​will​ ​compress​ ​the​ ​folder​ ​size​ ​by​ ​permanently​ ​deleting​ ​messages​ ​that​ ​have​ ​been​ ​marked​ ​for​ ​deletion.

Empty

This​ ​will​ ​trash ​all​ ​messages​ ​in​ ​the​ ​selected​ ​folder or permanently delete them.​ ​Be​ ​cautious​ ​when​ ​using​ ​this​ ​operation​ ​as​ ​it​ ​may not be undone.

​Manage​ ​Folders

Selecting​ ​this​ ​menu​ ​item​ ​will​ ​take​ ​you​ ​to​ ​the​ ​settings​ ​section​ ​where​ ​you​ ​can​ ​manage​ ​your​ ​mailbox​ ​folders.​ ​Here,​ ​you​ ​can​ ​create,​ ​delete,​ ​rename,​ ​or​ ​reorganize​ ​your​ ​email​ ​folders.

Quota​ ​Display

If​ ​your​ ​mailbox​ ​has​ ​a​ ​maximum​ ​size​ ​limit,​ ​the​ ​quota​ ​display​ ​in​ ​the​ ​footer​ ​of​ ​the​ ​folder​ ​list​ ​indicates​ ​the​ ​current​ ​usage​ ​of​ ​available​ ​disk​ ​space.​ ​Hovering​ ​the​ ​mouse​ ​pointer​ ​over​ ​the​ ​percentage​ ​display​ ​will​ ​show​ ​the​ ​actual​ ​numbers​ ​of​ ​your​ ​quota​ ​usage.
