After running this SQL script in SQL Server 2012:
ALTER TABLE table1
ALTER COLUMN name NVARCHAR(50)
I am unable to create a linked table from Access 2013.
The following error is displayed when I attempt to link to the SQL Server table:
The issue in this case ended up being a spatial index. Access would not add the linked table if the spatial index existed. I simply removed the spatial index temporarily, added the linked table in access and then recreated the spatial index on my sql column.
