Hi Alex,

As far as I know, the DateTimeStamp is an element in Exchange Server, there is “System.DateTime” in C#. Do you want to covert the string to System.DateTime, and sort it in ASC order? If so, I will recommend you add a new column, convert the string to DateTime,
add the value of the DateTime to the new column, and then sort by the new column.
For information about adding new column, you could refer the link below:

For information about converting the string to DateTime, you could refer the link below:
# How to: Convert a String to a DateTime (C# Programming Guide)
https://msdn.microsoft.com/en-us/library/cc165448.aspx?f=255&MSPPError=-2147217396
For information about sorting by the new column, you could refer the link below:
