Some users might face problems when receiving many emails at atime that makes them confused. So, this blog explains all about the Custom Folder Mapping process to solve this type of issue. So,read this guide if it helps you in understanding this topic.

Custom Folder Mapping:

Customer Folder Mapping is the process of moving data from one folder of an email client to a particular folder. Folders can be of any type as given below:

System Defined Folders:

An email client includes multiple system folders like Inbox, Drafts, Sent Items, Trash, Junk Emails, Tasks, Contacts, Calendar, and Journals. These folders are saved by default in an email client of the system. These folders cannot be changed or renamed by any user. But if you want to change any folder’s name then other folders are available.

User-Defined Folders:

A user can make a user folder in their email clients for receiving emails. If any user receives thousands of emails at a time then it would be difficult to manage all of them at a time. So, it becomes very important to make some rules and customize folders with the names from whom the email is sent.

Why do we need to use Custom Mapping Folders?

When we migrate NSF files into PST files then this time, the need for custom mapping folders becomes useful.

  1. If a user moves data from one email client to another one, then the platform may differ in languages. At that time, this custom folder mapping helps in mapping one system folder with other system folders.
  2. When moving data from one email client to another then there could be a need for showing the source of data using different names. This can be possible by archiving the data from the previous file into newly created files with different folders’ names. At that time, this custom folder mapping option helps in mapping the system folders with user-definedfolders.
