Why are emails being shown twice?

As explained above, Outlook might show your emails twice if the sorting filter is not set to ‘Date.’ Unless you set up your mailbox to duplicate emails, that is the most common reason emails show up twice. There are other less common reasons why your emails are showing up twice in your inbox.

For example, many Outlook users commonly use the same Outlook account on multiple devices, including desktop PCs, laptops, tablets, and mobiles. That can lead to numerous copies or duplicates of emails. Unfortunately, there is no quick fix to that issue as you will have to delete the duplicate emails manually.

Another reason your Outlook may display emails twice is that you may have your emails set to archive. That means that each time you receive a new email, a copy of the same email will also be saved in your archive file. When Outlook is set up to archive messages automatically, it often ends up duplicating them as well.
