How Do I Delete Multiple Emails In Outlook And Why Do I Need This
If a user has noticed the duplicates only once, it is feasible to remove them manually. Deleting repeated emails is one of the easiest ways, however, it is important to be sure that you really deal with duplicates not emails with a common subject. Verifying the size, date and time of receipt should be the first step before you delete multiple emails in Outlook.
To remove duplicate emails in Outlook 2007 or any other version, it is necessary to find the first message and right-click it. Hold Shift and scroll down to the last repeated email, press on Delete. This is when it is necessary to delete consecutive emails. If messages are non-consecutive, it is necessary to hold Ctrl and right-click on all the emails to be deleted. When all of them are chosen, press on Delete.
If the situation repeats, it is not a way out to simply delete duplicates. Their accumulation will lead to the increased storage volume required for Outlook, thus, the work of a PC may become slower. What is more, due to the high number of messages, the function of the search will work too slow as well. Thus, finding an Outlook duplicate items remover makes sense.
Problems Created By Duplicate Email Messages
As you probably know, Outlook is one of the most complex and resource-hungry applications of the Microsoft Office suite. It requires quite a lot of resources for smooth performance, and the more email items you have, the more memory, disk space and CPU usage it consumes. Finally, it may reach the point when the existing resources do not suffice and your Outlook will start to slow down in performance. For example, you want to find a particular message using Outlook’s Instant Search, but all that you see is “Searching“. And you have to wait patiently while Outlook iterates through all email messages in a given folder including duplicated ones.
On an average PC, Outlook starts to slow down when the mailbox reaches 2-3 GB, and if you don’t reduce the size of your mailbox and Outlook data file , your Outlook may start hanging, freezing and not responding.
