Five good reasons to remove duplicate Outlook messages:
How to determine that messages are duplicates?
The answer to this question is not as obvious as it may seem at first glance. To understand which messages are duplicates and which are not, you must compare their significant fields and properties. For example, you can select these fields for comparison: subject, text, sender, recipients, and attachments. If these fields have the same values for multiple messages, it can be concluded that such messages are duplicates. Dates are rarely used to detect duplicates because duplicates are often several identical messages sent at different times.
Detecting duplicates within a date range
If you know exactly where duplicates appeared, for example, over the last few days, set the filter by dates. Removing duplicate messages over the past week will work much faster than removing duplicates from the entire mailbox or data file. When periodically deleting duplicate messages from public folders, it is enough to make a complete duplicate deletion once. In the future, it is better to use a constrained deletion, for example, only for the last month.
Save your time and don't make mistakes!
You can delete duplicate Outlook messages manually, but it is hard and time-consuming work. You will need to compare many messages using several criteria. Perhaps comparing a couple of dozen messages in one Outlook folder will not be a problem. However, if there are tons of duplicates in different folders, this becomes a difficult problem to solve. Most likely, you will miss something or delete more than needed. Using our program will save your time and save you from errors.
What can you do with duplicate messages in Outlook?
Removing duplicates from one or more folders
If duplicate messages are in different folders, set the "Search duplicates across the folders" option. In this case, the utility first searches for duplicates in all selected folders, and only then deletes them. To keep original messages their places, specify the folder priorities. For example, when using Outlook/Exchange rules to sort received messages in different folders, it's convenient to add the "Inbox" to the low priority list. In this case, messages sorted by rules will always be considered originals, and duplicates in the Inbox will be deleted.
When searching for duplicates in multiple folders at once, your messages will remain in some places, and duplicates in other places will be deleted. Configure folder priorities to specify which to leave messages in. You can add any Outlook folder to the high or low priority list. The utility leaves the same messages in those folders with the highest priority. If a duplicate is in the folder with a lower priority, it will be deleted. If you don't use the folder priorities, the utility will delete the messages created recently, leaving those that are older.
Removing duplicates during email migrations
Migrating mailboxes from other mail systems or mail programs is a complex process fraught with errors and failures. Sometimes, user mailboxes or public folders are migrated to a new system along with redundant duplicates. To address such problems, often unique to the particular organization, the ability to remove duplicates using a command line is provided. As a command line parameter, you can specify the list of mailboxes, public folders and PST files requiring mass de-duplication. You can use the command line application in your PowerShell scripts, batch files and other scenarios.
