01/01/1753 date is corrupt in Excel after export from SSRS
Excel specifically provides a message: Dates and times that are negative or too large are displayed as ######.

So, that is a Excel limit.  Further, you can type in strings that look like dates, but Excel may not think of them as dates. For example, if I make a column of date type and enter into the columns -53689, 01/01/1753, and 01/01/1900 (using my settings) I get this:

####################
01/01/1753
            1/1/1900


So, it is easy to see that these are not all being interpreted the same by Excel.
