Update: The below work has been partially completed. We’ve changed the migration strategy to use public folder replication instead of an in place reload. This decision will extend the maintenance interval into next weekend but will provide no downtime for mailboxes or public folders
Over the weekend of March 30th– April 1st we will be performing upgrades to the LOUIE DAG (Mailboxes) and Public Folder databases. The changes that will begin during this maintenance cycle will improve the native automatic redundancy for LOUIE mailboxes and bring an overall greater experience for users. Due to the number of users and the size of data on LOUIE, the only way to complete the migration with the overall least amount of service interruption is to dismount the public folder database on Friday evening, and leaving it dismounted until Saturday afternoon.
Taking the public folder database offline will prevent ALL access to public folder data housed on LOUIEMBOX1, including mail enabled public folders between Friday evening until Saturday afternoon.
All public folders are replicated between multiple databases, however, unlike DAG protection, Public Folder databases work off a referral based system for locating copies and is highly unreliable for automated continuity.
Any users/partners who are concerned about the availability of their public folder data can open a support ticket and request that our team ensures their public folder data has an active, local replica.
We do not anticipate any interruption in the service of actual mail delivery or mailbox access on LOUIE.
