Is it possible to restore emails on the computer?

My laptop's Outlook pulled all the emails…

I restarted my laptop after about a year…

He pulled all the e-mails so that I only have the e-mails of the last 2 weeks in both the Outlook of my PC and in the webmail inbox…

Since I no longer use the laptop…

How do I get all the e-mails from the laptop back into the webmail inbox or back onto the PC?

Although your terms are a bit unclear to me, the following:

Emails are usually stored in the mailbox until they are deleted there.

But you can set in Outlook that e-mails that have been fetched are deleted from the mailbox.
So, go to the email account with the browser and look there!

Yes, by webmail inbox I mean the browser…

The e-mails are gone there as well as on my PC.

Unfortunately, you are only on your laptop…

You can't go back to the mailbox, but you can save the emails on the laptop, see https://praxistipps.chip.de/...atte_13044, and then transfer them to the PC.

Your laptop apparently retrieves the emails with POP3 and you deactivated the setting "Leave copy of email on server". As a result, he has downloaded all emails and deleted them on the server.

The easiest way:

You export the emails from Outlook (File → Export). Then you should switch the retrieval method from POP3 to IMAP either on the laptop or on the PC (maybe even IMAP is already set on the PC, you can see that). Then you simply import the emails back into the mailbox and they are automatically uploaded to the server and are available again everywhere. Just make sure that you either use IMAP on your laptop in the future or that the copy remains on the server with POP3

Great, thank you very much.

It is exactly like that…

Can you maybe tell me how I export or import the e-mails?
Unfortunately I can't find it in Outlook…

For the transfer between laptop and PC, I can save the exported file on a stick or in the Dropbox, right?

The export function is included as standard in Outlook. Simply go to "File" and then to "Open and Export" and select Import / Export. Then just follow the guided dialogue.

Yes, you can then transfer the emails on a stick or via Dropbox.
