Privacy is a sensitive topic nowadays since you don’t know where your personal info may end up.

This is an issue that some users encountered:

I was cleaning up with WinDirStat when I found […] a lot of images and videos from years ago, the funny thing is these images and videos are from an old computer which doesn’t exist for a year, somehow these files were synced up to my account back then and now to my new laptop.

Apparently, users are highly concerned that their personal information may be synced with plenty of computers they no longer use.

However, further research revealed that the images and videos the user was using were, in fact, part of the Outlook cache:

[…]OP is seeing the cache related to the Mail app, and any emails and such that synced in regards with that.

What does this sync do?

In theory, this sync allows users to have access to their private files on pretty much every PC they log in with their account.

Unfortunately, this also means that those using public PCs are in danger of having their personal information made public.

As such, this article was devised to help you completely delete your Outlook cache step-by-step.

How can I delete synced files from other PCs?

1. Close Outlook if it is opened on your PC.

2. Press Windows + R to bring up the Run dialog.

3. In the Run dialog box, enter %localappdata%MicrosoftOutlook and hit Enter.

4. Enter the RoamCache folder to view the cache files.

6. Select all of the files you want to remove, then press Delete, or right-click the highlighted files and select Delete.

7. Outlook will automatically make new cache files when you open Outlook.

8. Keep note that if you want complete privacy, you have to repeat this process on any new PC you want to log in with your Outlook Mail.

2. Completely turn off Indexing on your PC

1. Press Windows + R
2. Type in control.exe
