Rules for creating folder names
In addition to the folders that are standard in the mail file, you can create your own folders that display in the mail navigation pane. When creating a folder, you should be aware of the limitations for folder names. The limitations apply whether you are using the Notes® client or the web client.
- Underscore (_)
- Backslash (\)
- Vertical bar (|)
- Control characters (codes less than Unicode 32 decimal) cannot be used. For example, do not use tab as a character in a folder name.
- Parentheses can be used in some parts of the name. You can use a single parenthesis, such as animal (names, or enclose a portion of the name in parentheses, such as animal (names). However do not enclose the entire name in parentheses, such as (animal names).
The full folder name, including all aliases, can have up to 64 bytes. English characters each use one byte, but in other languages, characters often use more bytes per character. Subfolder names have a 130-byte limitation, which includes the backslash (\) character. The subfolder customers\issues\resolved for example, has 25 characters (25 bytes in English).
The total number of views and folders that can display in the navigation pane of the Mail application varies depending on the fonts used to display their names, as well as other factors in the design of the pane. Also note that some folder names are reserved for Notes application design, such as Inbox, Calendar, or Trash. These names should not be used.
