Microsoft's desktop database. The process is MSACCESS.EXE. It is missing from many Home Microsoft 365 SKUs. It is not Excel.

What you need to know

Access is MSACCESS.EXE. A big spreadsheet is still Excel, not a database.

Microsoft Access stores tables, queries, forms, and reports in an .accdb (or older .mdb) file. Many Microsoft 365 Family and Personal installs never place MSACCESS.EXE on disk. Excel is EXCEL.EXE.

What is it?: A desktop database app
In Home 365?: Usually no
Same as Excel?: No. Excel is a spreadsheet

Feex says

If Start search cannot find Access after a Home 365 install, I would check the SKU before I repair Word. Home plans often omit Access. Excel is not a replacement for an .accdb application.

What is Microsoft Access?

Microsoft Access is a desktop relational database bundled with some Office and Microsoft 365 business SKUs. The Windows executable is MSACCESS.EXE. It is not Excel and not SQL Server.

If you have never used it

If someone sent an .accdb file, you need Access or the Access Runtime, not Excel. Excel can hold a table. It does not run Access forms and reports. Many Home Microsoft 365 subscriptions never install MSACCESS.EXE. Check your plan or use a business SKU before you hunt for a missing exe.

What is it used for?

Desktop databases

Tables, relationships, and .accdb files on one PC or a small share.

Forms and reports

Line-of-business UI that Excel sheets do not provide.

Access Runtime apps

Some vendors ship an Access front end plus Runtime. That is still Access, not Excel.

Who is it for?

Offices that still run an .accdb line-of-business app
People whose Home 365 install never included Access
Anyone who should not open an Access app in Excel and expect forms

Current status

Still shipped in Microsoft 365 Apps for business and some Professional boxes. It is not in many consumer 365 plans. This article is desktop Access on Windows.

How old is it?

Access 1.0 shipped in 1992. It is an old desktop database, not a cloud warehouse. Current files are usually .accdb. A 2000-era .mdb may still open with warnings.

Common problems

Access missing after a Home 365 install

The plan likely never included it. Changing Word repair will not add MSACCESS.EXE.

People open .accdb in Excel

Excel may import a table. It will not run the Access application.

Getting unstuck

Check whether your Microsoft 365 SKU includes Access

Family and Personal usually do not. Apps for business and some Office Professional SKUs do.

Use Access Runtime only when the vendor says so

Runtime opens a packaged app. It is not the full designer and it is not Excel.

Compact and repair from Access, not from Word

A bloated .accdb is an Access file problem. WINWORD cannot compact it.

Alternatives

Excel, SQL Server Express, and a web app overlap for data. None of them run an existing Access form without migration.

Related hardware

A local .accdb wants reliable local disk. Putting the only copy on a flaky USB drive is a common way to corrupt it.

Technical details

Whether Access is installed depends on the Office SKU, not on the Word build number.
