@Users,

Most common reason for such change is when folder was deleted and then created with the same name – UIDVALIDITY must be different in such case to allow client to recognize that this a different folder.
If you want details you’ll need to look in RFC3501 e.g. 2.3.1.1.

In most modern servers UIDVALIDITY changes rarely. However client that remembers message UIDs between sessions must deal with such change and act accordingly.

When i create it, was assigned as 10. after multiple session workout and new and existing email changes, still it has 10. May i know what is its actual Purpose
