Hello, we have this issue for some years. When i add in Outlook (German) an IMAP Account, some of the Foldernames are in English. It does not matter if i use an existing mailbox or create a new one. In webmail they are in german. currently i am using version 9378. 

I tried this with Outlook 2021, 2024 and MS365. There were never german names (in former SM versions the names were also always mixed in german and english). 

If i add it in MAPI or EWS, the foldernames are in german. Now i have some customers who want the names in german, so i am writing this question again: Why are the names from IMAP Mailboxes not in the right language?

regards

Rudolf
