Quite a significant number of Outlook users have recently reported they can’t use their Outlook account properly due to an error message informing them that their mailbox folders have conflicting names.
Outlook users rushed to the Microsoft Forum searching for a solution, only to get disappointed. Microsoft’s Support engineers suggested using a different web browser, but haven’t been able to offer a permanent solution.
Here’s how the exact error message appears:
One or more folders in your mailbox have name conflicts with others or system reserved names.
Folders with these names can’t be downloaded by your IMAP e-mail program.
Please connect to your mailbox using your Web browser and rename those folders. Once renamed, those folders will be displayed in your IMAP e-mail application correctly.
Some users, and even Microsoft’s Support team even went as far as stating that these messages could actually be phishing attempts, because the green shield was not visible on the emails. Users even marked the emails as phishing, but this strategy didn’t stop them from landing in their mailbox.
However, after scouring various forums, it appears the emails are genuine, and fortunately there is a simple workaround which you can use.
One user noticed that he had two similar Outlook folders, Junk and Unwanted, and renamed the Junk folder. Soon after, the emails about the conflicting name folder ceased to come.
In other words, the solution is to simply rename the Junk folder.
Another user’s comment on Microsoft’s Forum confirms this hypothesis:
I keep getting the below email appear in my inbox, when I delete it, another one appears within a minute.
I have also had a look and do not have 2 with exactly the same name. I have Junk and Junk Email.
Perhaps Outlook considers that the two folders, Junk and Junk Email, have similar names, which creates the conflict leading to those folder name emails being sent.
So far, this is the only solution confirmed to have worked. Do try it, and tell us in the comment section below if it worked for you as well.
