Hello, I spend last 2 day connecting clients to mailcow using IMAP. If a client is Outlook (multiple version), some of “default” folders are not translated to language of client. Inbox is OK, but Trash and Junk are not translated. Some of those people do not speak English, so it is quiet problem for them.

So far i find this thread, I’m not sure if it is still current,… mailcow community Icon IMAP - Folders in french language

translation are now located in dovecot.folders.conf I can see correct translation for Trash like mailbox "Odstraněná pošta" {special_use = \Trash}not sure if I need to override this in extra.conf,…

Sadly those folder can be renamed in Outlook :-(

Also there is command outlook.exe /resetfoldernames but this create new folder in native language and keep old english one, this is also confusing having 2 folders, Sogo will for sure use “english version”. Sogo shows correct translation from the beginning. Also Thunderbird have no problem at all :-(

This image show folder after resetfoldernames in outlook

Before mailcow we were using simillar stack postifx/dovecot and so, this was not an issue.

I will be grateful for any advice

Yes, I did mention this post,..

So far i find this thread, I’m not sure if it is still current,… [link] translation are now located in dovecot.folders.conf I can see correct translation for Trash like mailbox "Odstraněná pošta" {special_use = \Trash} not sure if I need to override this in extra.conf,…

Translation is already there, not sure how to define it in different way :-(

3 months later

Did you find a solution for this? I’m having same exact issue with oulook 2021 and italian language, I created extra.conf file with this content

`namespace inbox {
inbox = yes
location =
separator = /

mailbox “Posta inviata” {
special_use = \Sent
}

mailbox “Bozze” {
special_use = \Drafts
}

mailbox “Posta indesiderata” {
special_use = \Junk
}

mailbox “Cestino” {
special_use = \Trash
}

mailbox “Archivio” {
special_use = \Archive
}
}
`
but is not synching the language

Nope,..

I do not believe, this is possible in Outlook using IMAP, Outlook is garbage, if you must buy MS Office, buy lower tier (Word/Excel only) use Thunderbird and save some money :-)

Edit: There is one possibility, that I did not try and I do not believe it is good idea in Mailcow, You should be able to force Dovecot make translated folder instead of English, than Outlook download this translation. BUT there is high possibility you will need to reconfigure much more and future update will break your changes,…

    ETNyx crazy that such a bug is not fixed in 2024

    It’s a feature to forcing people to use their solution, preferably on monthly subscription.
