- Open Outlook. In the folder list, click Search folder, then select New Search folder.
- Scroll down the list and under Organizing Mail, select Large mail. Click Choose under Customize Search Folder.
- Specify a size in the ‘Show mail greater than’ box (for example 6000 KB). Click OK to continue.
- Click OK again and a folder named ‘Larger Than 6000 KB’ is created under Search Folders. This newly created folder will get updated with the mails of size more than 6000 KB automatically.
When you face mailbox size issues, just go to the Search Folders. There, click on the newly created folder, and delete your mails which are not so important. If you need, you can save the attachments to your drive before deleting it (by right-clicking on the attachment and then clicking ‘Save As’ or ‘Save All’ option). Continue doing this, until the mailbox has enough space for new emails.
