Resolving the 'Hotmail Mailbox Full' Issue
If you're a Hotmail user, you know the pain of getting a notification that your mailbox is full (the dreaded "Hotmail Mailbox Full"), hence you can't receive incoming messages or send emails.
This issue stems from old, unattended mailings that consume storage space as they accumulate through the years. Sometimes, merely deleting messages from your inbox does not resolve the issue.
Many users are left wondering: What else should they do?
Here's the thing—it takes more than knowing how to mass delete Hotmail emails.
You can nip the problem in the bud by managing your emails regularly and setting up a system to declutter your Hotmail inbox.
How to Delete Multiple Emails in Hotmail
An important caveat: While you can't log into Hotmail anymore, you can log into your Hotmail address through Outlook. So, the following steps on how to delete emails in Hotmail focus on the Outlook.com web interface.
There are three ways to delete multiple Hotmail messages:
1. Deleting messages in bulk:
- Click the first email.
- Press and hold the Shift ⇧ key.
- Click the last email.
- To unselect an email, press and hold the Ctrl / Cmd ⌘ key, and then click the email.
- Press the Delete key (or right-click and delete).
- If you wish to delete all emails in your inbox, press Ctrl / Cmd ⌘ + A to select all. Then delete.
2. Deleting non-consecutive emails:
- Click the first email.
- Press and hold the Ctrl / Cmd ⌘ key.
- Click the emails you want to delete while holding the Ctrl / Cmd ⌘ key.
- Press the Delete key (or right-click and delete).
- To unselect an email, press and hold the Ctrl / Cmd ⌘ key, and then click the email.
3. Deleting emails one by one:
If you want to be more intentional with the messages you want to get rid of, you can also delete emails individually—albeit taking longer than the first two methods.
- Find the message and click on the Delete button (with the trash can) to delete it.
- You can also open the mail and decide whether the content is something you want to delete. If so, click Delete.

Set Up Outlook Sweep Rules to Delete Hotmail Emails
Did you know that Outlook has Sweep rules that work as smart filters?
You can create Sweep rules and apply the same action to bulk messages.
There are various Sweep rules, and depending on which ones you use, you can leverage them to automatically delete emails in Outlook and Hotmail.
- Log in to Outlook.com.
- Make sure you're in the Inbox folder.
- Open a message from the inbox.
- Find the Sweep button on the top menu bar.
- Tick one of the four pre-configured actions and choose where to move the sender’s messages, i.e., Deleted Items. You can select from pre-configured actions:
- Move all messages from the inbox folder
- Move all messages from the inbox folder and any future messages
- Always keep the latest message and move the rest from the inbox folder
- Always move messages older than 10 days from the inbox folder
💡 Note: If you can't see the button, check whether you have selected a message. It only shows up when you do this.

- Click OK to confirm.

How to Empty Deleted Folder in Hotmail
Many users who encounter issues emptying their inbox point out that merely deleting messages from this folder won't solve the "Hotmail Inbox Full" issue. They recommend emptying the Deleted Items folder immediately to free up storage space.
Here's how to delete all emails on Hotmail for good:
- Press Ctrl / Cmd ⌘ + A to select all messages.
- Press Shift ⇧ + Delete to remove all contents in the Deleted folder.
- Press OK to confirm.
Common Mistakes When Deleting Hotmail Emails
Many users make simple mistakes that prevent them from actually freeing up space or keeping things organized.
- Not emptying the Deleted Items folder – Emails still take up storage until they are permanently removed.
- Ignoring the Junk/Spam folder – These messages can accumulate quickly and consume space.
- Deleting emails without unsubscribing – Newsletters and promotions will keep coming back.
- Forgetting about large attachments – Emails with files take up significantly more storage.
- Not setting up automation – Manually deleting emails without rules leads to the same clutter building up again.
