4. Remove or rename the problematic folders

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 IMAPe-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.

Outlook folders in your mailbox have name conflictserror can appear if you have folders that have the same name in your inbox. Many users reported that they have two Junk folders in Outlook, and this is most likely the cause of the problem.

Most users have only one Junk folder on their account, but if you have two Junk folders, you might be able to fix this problem simply by renaming or deleting one Junk folder.

According to users, only one of these folders can be deleted, so delete one Junk folder and check if that solves the problem.

If you don’t want to delete this folder, you can also rename it, and that will solve the problem as well. Several users suggested that you log in to the web version of Outlook and rename or delete the problematic directory from there.

Many users reported that this solution worked for them, so we strongly suggest you try it out. Although the Junk folder is the usual problem, sometimes you might see other duplicated folders.

If so, remove or rename them, and the problem should be resolved.

5. Use POP instead of IMAP account

If you’re having problems withOutlook folders in your mailbox have name conflictserror message, you might be able to fix the problem by using POP protocol when adding your Outlook account.

In case you’re not familiar, the POP protocol is older and has certain disadvantages over the newer IMAP protocol.

The POP protocol will download the email from the server so you can always read emails on your device, even if you’re not online.

However, this means that POP protocol doesn’t support email synchronization, so if you delete an email from one device, it will be still available on your other device since it’s downloaded to yourhard drive.

As you can see, the POP protocol has flaws, but several users reported fixing the problem by using a POP account as a workaround.

If you don’t plan to sync your emails on multiple devices, you might want to try using the POP protocol as a temporary solution.
