Has anyone please encountered an error, where mobile devices aosi/android sync only a few recent emails and some old emails from years ago? For example I have 25 emails from june 2021 and then 5emails from 2015, 10 from 2012 etc. Webmail and any PC client shows all emails correctly.
I have updated MIB to newest version, also the OS is newest version, but the problem persist.
This happens with emails, that were originally migrated with imapsysnc from exchange 2010 server.
I’d be grateful for any advice.
