Practical Checks That Prevent a Repeat

• Record which account, app, and file owns the workflow

• Save confirmation numbers, dates, and screenshots of the final settings when they affect billing, security, or permissions

Frequently Asked Questions

Should I check Outlook on the web when an item is missing?

Yes. The web mailbox helps distinguish a server-side folder or rule issue from a desktop cache, view, add-in, or data-file problem.

Where can I recover deleted Outlook items?

Open Deleted Items and use Recover items deleted from this folder when available. Calendar items may appear in the same recoverable-items store.

Why can an Outlook add-in disappear?

It may be disabled, blocked by policy, incompatible, or not deployed to that account. Check File > Options > Add-ins and the Microsoft 365 admin deployment.

How can I confirm that finding Outlook messages that do not appear in the inbox was successful?

Move one located message back to Inbox and confirm that it appears in both Outlook on the web and the desktop app. Repeat the original action and confirm that the result remains after reopening the app, file, or portal.
