But before we begin recovering, let’s see in which cases the restoration is impossible.

Instances When You Can’t Restore Files

There are some cases when the recovery of deleted messages is impossible:

  1. You have cleared the Recoverable Items folder;
  2. More than 30 days have passed since the deletion;
  3. You don’t have access to eDiscovery or you don’t have an Enterprise license.

In these cases, unfortunately, you cannot recover deleted messages in your Outlook. This is why we strongly recommend you use secure third-party backup services.

With that being said, let the recovery begin! 

1. How to recover deleted emails in Outlook if you don’t have a backup

Can deleted emails be retrieved in Outlook? Sure they can in all cases except the ones laid down in the previous section of this article. Let’s take a look at how to do it.

There are some first obvious moves you should take whether or not you have a backup. They include going through your trash bin and Recovery folder.

1.1. How to retrieve deleted emails through the Deleted Items folder 

In some cases, you can recover deleted Office 365 emails in a few seconds. But to make it possible, two conditions must be met: 

1. It should be less than 30 days from the removal date. All the files in the Deleted Items folder are removed automatically after 30 days. 

2. You haven’t deleted anything from the Deleted items folder. 

If you still have time and you haven’t emptied the bin yet, you can proceed. Here’s how to find deleted emails in Outlook.

Undo delete in Outlook in browser:

1. Open your Outlook.

2. Go to Deleted items folder (trash folder).

3. There you will see all the emails you’ve deleted. You can restore one particular item or all of them. To restore one item, navigate on this email, put the radio button near, and click Restore. The email appears in the folder it was deleted from.

To restore all the deleted emails, click Restore without selecting any particular emails. By default, all the emails will appear in the first folder.

On the Desktop:

1. Open your Outlook.

2. Go to the Deleted Items folder.

3. There will be your deleted emails. Right-click on the email you need to recover and choose the option Move > Other Folder. In the next window, select the folder to move your item to and press OK.

Unfortunately, there is no option to restore all emails with one click like in the Web version. You may need to go through all of them separately, which can take some time. 

However, how to recover the emails deleted from the trash in Outlook? Or what to do if it’s been more than 30 days since you deleted the emails? Don’t panic. You still can restore your data using the Recoverable Items folder if you delete email Outlook.

1.2. How to recover permanently deleted emails in Outlook through the Recoverable items

Microsoft doesn’t provide you with backup options (except if you are subscribed to the Enterprise license), but it gives you two options to recover deleted emails instead. The recoverable Items folder is the second step for those who rashly cleared up their Deleted items folder, or who deleted emails more than 30 days ago. In these cases, Microsoft gives you one more way to restore.

1. Go to Deleted Items.

2. There is a Recover item deleted from this folder link above. Click on it.

3. To select everything, put a tick near the Recoverable Items. To recover particular items, you can click on them or the radio button near them.

4. Press Restore. 

Now your files are restored. Depending on the version, you can restore them either to the initial folder or the Deleted Items folder, so check both.

Again, you have 30 days until all the emails are erased from this folder. 

2. Recovering Emails if You Have a Native Backup

By “native backup,” we mean Microsoft tools that were initially designed for other purposes but people often use it as a backup. We covered all of them in our guide How to Backup Office 365 Emails in Just a Few Clicks

There are four of them:

  1. Auto-Forwarding
  2. Export/Import wizard
  3. Auto-Archiving
  4. eDiscovery

We won’t cover the first two here, because they are self-evident. If you use auto-forwarding, you can restore lost emails by going to the spare email you forward messages to. If you saved data with Export/Import wizard, you should go to where you saved the .pst file with your emails. 

Here we will focus on how you can restore your emails using the Auto Archive and eDiscovery search. 

Recover emails in a couple of clicks

Start now!

2.1. How to recover deleted email through the Archive folder

Auto-Archiving gives you the ability to move your old emails to the Archive in case you need them later. It is available only on a desktop Office 365 version. 

Sometimes Auto-Archiving is set by default for all corporate users of Outlook. In case you didn’t know this function was set up, you may have missed the moment when all your old emails were transferred to the Archive folder. And, therefore, consider them deleted. 

If so, you can find all your lost emails in this folder and recover them. 

1. Open your Outlook.

2. Press the Archive.

3. Now you can choose whether to move back all the emails in the folder or choose a particular one. 

4. When you picked the emails out, press Move to > Inbox (or any other folder).

Done! Now you can find the restored emails in the specified folder. 

2.2.How to recover deleted email through the eDiscovery

eDiscovery is a tool that helps search information for legal cases and use it as evidence. But it also could be used as a recovery tool. 


  1. Only IT administrators have the right to use this tool. If you are not an admin, you won’t be able to recover emails. You need to contact them for conducting this procedure.
  2. This feature is available for Office 365 Enterprise subscriptions only. 

If you are an administrator, follow these steps to recover Outlook emails:

15. To find deleted files, you need to specify the email address. First, choose Specify mailboxes to search, then Add a mailbox. Press Next.

16. To narrow your search, choose Filter based on criteria. These criteria can be different: you may remember the keywords in the email, or it could be a time frame you have received or sent a particular email. When typing the keywords, do it separately. 

17. Then, press Select message types to search. This is another filter to help you distinguish the type of the file you are trying to find. If this is an email, specify it.
