The November Patch Tuesday Office release introduce an issue with Access queries. A change to fix a security vulnerability causes some legitimate queries to be reported as corrupt. The update is 1328.20468; it was released Nov 12, but hasn’t rolled out to everyone all at once.
Because the change was a security fix, it impacts ALL builds of Office, including 2010, 2013, 2016, 2019, and O365.
The bug has been fixed in all channels, but the timing of delivery will depend on what channel you are on.
- For 2010, 2013, and 2016 MSI, and 2019 Volume License builds, and the O365 Semi-annual channel, the fix will be in the December Patch Tuesday build, Dec 10.
- For O365, Monthly Channel, and Insiders, this will be fixed when the October fork is released, currently planned for Nov 24.
If you can, you might want to hold off on updating until Dec 10.
The issue occurs for update queries against a single table with a criteria specified (so other types of queries shouldn’t be impacted, nor any query that updates all rows of a table, nor a query that updates the result set of another query).
