Frequently Asked Questions

Why is Access showing data-change messages when I haven't changed anything?

This is a known bug in certain builds of Microsoft 365 where the form's close event incorrectly triggers a transaction or data-change prompt, even in single-user databases with no close code.

What does changing the Microsoft 365 update channel do?

It changes how frequently your Office applications receive feature updates and bug fixes. The "Current" channel receives updates as soon as they are ready, allowing you to get immediate bug fixes for issues like this Access glitch.

Will running the OfficeC2RClient.exe command delete my Access database?

No, running this command only updates the Microsoft 365 application files on your computer. It does not affect, modify, or delete your personal databases or records.
