Hi,I have an Office 365 Account. In August 2012, my system crashed and I had to reinstall all software.
Remove Duplicates from Outlook Express Overview Duplicated messages appear in Outlook Express every time the connection with the mail server fails. They can also appear as a result of different synchronization errors or message import errors.
I had been storing all my Office 365 mail data in a.PST file. To save the trouble of downloading all my mails again, I just backed up all data from the.PST file.I later observed that when I connected to the internet, all my mails started downloading again as a result of which I have a lot of duplicates mails in various Outlook mail sub folders.How can I delete these duplicate mails from Outlook and the server. I am in the same boat with you.I used a 3rd party program called Osasync to sync my desktop and laptop so that Outlook would appear identical on both. It was a nightmare.
I had tons of error messages, Outlook froze up about 6 times a day and I had to alt/ctrl/del to get out, and ittook an entire day to sync.So I uninstalled that awful program from both computers and when I re-synced Outlook, it brought in 12,000 messages to my sent email box (from the cloud storage where the sync emails were stored). There were 6 of every email. The Outlook clean up tooldoes not work. I just get an error message saying that none of the dupes meet the standards set for the cleanup tool, or something like that.So just wondering if you have found a way to get rid of your dupes. I am petrified to try 3rd party solution since I had such a bad experience last time I waded into that water. Thanks!Hi CaroleAnnAustin.
