Zimbra Forums

It's been nearly a month since my group and I have migrated to Zimbra, and it's working great except for me. My session expires at random intervals, and I'm redirected to the login page even if I'm writing a message or fiddling with my user settings without notice. I've noticed recently that I can reproduce the problem by creating an entry on my calendar though -- just filling in dates (without saving the entry) is sufficient to kick me out.

I've tried different browsers and computers but the problem persists. Any ideas how to solve this? Thanks!
We're using Zimbra 8.8.15.

This happens to me as well and has for some time. I am also on 8.8.15
Often my account is locked after it happens. It is probably happening to
other users they either aren't reporting it or aren't looking at it or using
it when it gets kicked. Unfortunately I haven't been able to find a reason
as nothing is ever logged about it.

happen to my team where user will get locked status after few months usage. is there a proper method to trace account locked from log file? I have tried /opt/zimbra/log/audit.log and others
