Good Day!

                I have a fairly new user on my network that has, over about 10 months, created in root inbox and nested sub-folders totaling over 900 individual folders.

                In the past few weeks, newly created folders will be visible in Outlook 2013, but when an email is moved into that folder, it is no longer visible. I can ssh into the server, drill down to that sub-folder and see the email in the folder AND it is also available to be seen without issue in Thunderbird.

                I know this is a longshot, but if there is some feature that I haven’t found in Dovecot to force Outlook to synchronize with all the folders/sub-folders, please let me know.

                Beyond that… With this particular users habits, over the next 5 years, there could be nearly 10,000 folders/sub-folders. Does anyone know if this will create any problems with Dovecot or is this JUST a Microsoft software problem?
