In specific situations, it is necessary to find messages that contain a specific date reference, for example: 12/2/16.
When searching in Retain, the / will be seen as a space rather than the mmddyy separator.
Enter the specific date criteria in the following format: 12?2?16.
The â?â will match exactly one character.
