This article provides information about Access bugs reported during Sept 2025 (in order of date reported) including symptoms and action taken.
Relatively few and relatively minor issues this month.
IMPORTANT:
Insider channels (particularly Beta Channel) are used by Microsoft to test new features before these go to production channels. It is to be expected that the insider channels may contain bugs. These channels should only be used for testing purposes and NEVER for production use.

| c) | Calculated Field Errors The Expression Service includes various operators that don’t work in table level calculated fields e.g. Mod & Integer Divide (\) and trigger an error. For example:  For details, see related article c) below. Both operators work correctly in a query calculated field Workaround - do the calulations in a query (recommended). Or, at table level, use other methods of calulating the fields in place of operators causing errors. |
