Hello,

Did you find any "Unrecognized VM option ‘PrintGCDateStamps’" message in zmmailboxd.out?

Is there any error log in mailbox.log as well?

Which files have you received from the Sectigo?

Re: Dumping 6 years of old e-mails

Hello,

You could try with the Enable Message Disposal in the folder properties:

Zimbra will automatically run the purge of the old messages.

Re: last logon time-stamp showing 3 hours ahead

Hello,

zimbraLastLogonTimestampFrequency is always registered using UTC.

The reason is to have a unique timestamp even if your users are using Zimbra from different timezones.
