Please see the enclosed notes from the Zimbra admin team. Thanks!
Saturday, May 25, we will be upgrading the Zimbra servers:
- OS patching and maintenance will be done
- more memory will be added to each server
- Zimbra will be upgraded from 7.2.2 to 7.2.3
The maintenance window for this procedure will begin at 9am on that Saturday. We anticipate completing the upgrade process by 2pm the same day.
During this period, the Zimbra server will be unreachable. You will not be able to check your mail, calendar, or anything else that is stored on the server. Incoming mail will be held and delivered when the OS patching is complete; no mail will be lost.
Upon completion, we’ll send an “all clear” message with any pertinent details.
If you have any questions or concerns, please contact your Zimbra Domain Admin, or your IT support staff.
