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?

I am only marveling at 900 individual mailboxes! That kind of situation tells me that the individual does not need to use e-mail anymore for their work. Maybe a CRM system. I am thinking along the lines of having 900+ labels on gmail....

Anyway, I know Timo has a better answer for you.
