Thunderbird shared folder - sub folders not shown

[tom2810]

Hi all,

I have an issue with Thunderbird.

I shared a folder (full admin rights) which includes sub folders. In WebApp and Outlook it works perfectly, but in Thunderbird I only see the main folder without sub folders.

The sub folders are also missing in "Subscribe" menu. Only the shared main folder are visible.

Zimbra Version:
8.7.11_GA_1854.NETWORK
Thunderbird 52.40.

Does anyone can help?
Thanks,
Best Tom
