Have you ever got a bunch of redundant duplicated email items, contact persons and calendar entries in Outlook and wanted to quickly clean up your inbox so you can focus on stuff that needs to be done?
If so, this post will be helpful. As today we’ll show you how to delete email duplicates without purchasing a costly duplicate remover tool for Outlook 2016.
We’ll first summarize the key reasons for email duplication. We’ll then provide simple solutions that you can easily implement to cleanup redundant conversations, contacts and meetings from your email inbox.
From what i have seen in the past, Outlook dups are usually generated due to six main reasons:
- Rules not configured correctly: There might be cases that two or more rules are fired upon receiving email, resulting in multiple instances of the same messages.
- Incorrect account setup: In several cases, i have seen that users mistakenly defined multiple occurrences of the same email account and this results in multiple instances of each incoming email, contacts and calendar entries.
- Send / receive interval are too short. If the frequency of your inbox update is too short; Outlook might load the message into your inbox, BUT might not be able to mark messages occurrences as synchronized/loaded. This results in multiplied occurrences of the same messages.
- Synchronization issues: We have also observed duplicated contacts and messages resulting from sync problems with 3rd party providers.
- User errors while manually copying and pasting meetings and appointments in the Outlook Calendar.
- Incorrect merging of several Outlook personal folders (also referred as PST files) into one folder.
Impact of duplicated Outlook items:
- They harm your productivity.
- They confuse and cause errors. Just imagine replying more than once to the same note
- They might impact your Outlook client loading performance. The more messages stored on your computer or server it will need to load on startup, the slower Outlook will be for you.
- They fill up your inbox. Business users will need to delete email to to comply with the allocated email storage capacity provided by their IT department.
Now that we understand the root causes and impact, let’s focus on solutions.
