Hi,
I'm Carlos Miranda, a portuguese Systems Admin for almost 10 years now, designing and implementing systems and infrastructure, with high availability, resiliency and loadbalancing in mind.
I have vast experience in systems, virtualization, and storage. I have worked as sysadmin in clients of many business areas, bank, government, aeronautics.
I'm also MCP and MCSA certified by Microsoft, with high experience designing and implementing Microsoft based systems, and Linux solutions, on premises and in cloud providers.
Hypervisors from vMware, Hyper-V and Xen/KVM.
Networking/security solutions of Checkpoint, Cisco, SonicWall, Juniper, PfSense.
The easy way to go in this situation, and if you don't want downtime, doing an integrity check on the database where the corrupted mailbox is, is exporting the data to a .pst, deleting the mailbox, and creating a new one, importing the data to it after that.
I'll be available during 9am to 8pm WET, with immediate answer, for any inquire on my proposal.
Kind regards,
Carlos Miranda
