Hi Marc,
Excellent explanation!!!. Yesterday, we had upgraded to Obsidian and....suddendly our customers were unable to see any inbox folders content after that.
We have changed today to Roundcube and customer webmail accounts work very accurate.
Thank you very much for your help!
Have a nice day,
Hugo
