Hi, I have an issue with IMAP client (Outlook 2013) and a quite large mailbox (about 30 GB).
Outlook is still synchronizing inbox, but this task never completes (and quite often, Outlook crashes so I need to manually kill process and restart it).
I already disabled Kaspersky plugin, which was one of first suspects for this behavior.
OS is Windows 10.
Can you give me some hints to troubleshooting this issue?
Thank you

if you are downloading all email as part of the IMAP profile config, you will have issues with a mailbox of that size

one option is use the "slider" to store more recent email locally....

I've read several articles about sync issues in MS Outlook 2013 due to KB2837618 or KB2837643. Can you check if you have them?
