Have you got some folders like Drafts, Sent items, Deleted items,... (or the translation of it in your language)?

I've seen users on my server with a folder named Bozze (italian translation of Drafts) and so the users cannot change the languages. 

Of course we see a localized versions of the main folders, which comes from SmarterMails. I also double checked some folders to be sure, that the names are okay.

Sorry for the inconvenience on this! This issue arises due to duplicate folder names matching our existing root folders in the chosen language. To correct this you'll need to switch the user to English, modify the offending folder name, then select the appropriate language in the user's settings. 

Hi Kyle

What is the "root folder" in the WebMail? I have Inbox, Deleted Items, Drafts, Junk Email and Sent items.
Please describe this more detailed.

Why this happened after the update? We have until today around 40 complains about this. A manual fix would be very expensive for me. It's actually a no go.

Thanks!

I'd be happy to clarify on this Martin. Regarding the issue you're seeing with the translated folder names... In the previous version of SmarterMail, there was a bug that allowed email clients to create the default folder names in the translated language (such as Inbox or Drafts.) However, that has been rectified in builds after 7593. Unfortunately, any custom folders that were created in the user's language will need to be manually resolved. I'm afraid we don't have a tool that will fix automate this process. To correct that you just need to set the user's language to English, rename the offending folder names to something that doesn't match Inbox, Drafts, etc in the translated language, then set the user's language back to the desired language once that has been cleaned up. I hope this helps! :)

Hi Kyle

If you try to switch to german language, that could be the folder Entwürfe conflicting, as it sounds a bit like a Draft folder in german.

Try removing/renaming this folder before attempting to switch the language again.

You can't rename them. These folders are provided by SmarterMail and they can not be deleted or renamed.

@Kyle: Please escalate this. This is a bug.

Thanks!
