A family of Microsoft relational database management systems designed for ease of use.
Me too am having same problem. Version 2205 update is the culprit. Any table with varchar as primary keys are affected with the #Deleted problem. Rolling my Office 365 back to version 2204 has fixed this for now. I'm using ODBC MySQL connector for my linked tables. Microsoft please fix this asap as this is a critical problem. I've many clients affected and not being able to access their database!
