Customer experiences

Customer experiences Data gathered from existing Office 365 MT and Office 365 GCC customers who migrated from on-prem environments Illustrative of what other customers have seen Trends and averages are fairly consistent

#1-Federal Government Agency Civilian Public Sector, cabinet level agency 24K users 18K in DC area with centralized Internet 6K spread across US in 4 offices with own Internet Migrated from Exchange 2003 98% in cloud 2% on-prem MX remains on premises O365 outbound routed back to on-prem Already constrained, ordered 4X circuit increase Main office went from dual OC-3 to dual OC-12 Remote offices ordered comparable upgrades Average 24% increase in their Internet utilization

#2-Commercial customer Shipping Company 15K users Global distribution 9K spread across North and South America with centralized Internet, 6K throughout EMEA Migrated from Lotus Notes and Exchange 2010 90% in cloud 10% on-prem MX remains on premises O365 outbound routed to Internet Customer had ample bandwidth in both central office and regions Average 20% increase in their Internet utilization

#3-Non-profit Qualified as a GCC customer 70K users Broad distribution throughout the US One central operations office (5K) and hundreds of regional offices (65K) Migrated from Exchange 2003 and multiple independent systems Major consolidation effort, including regional offices that used personal email accounts 100% in cloud MX to Office 365 O365 outbound routed to Internet Average 10% increase in their Internet utilization at central office No impact to regional offices

#4-Commercial customer Logistics and manufacturing company 20K users US based, with global operations including South America, South Africa, EMEA and APAC Tenant in NOAM Migrated from Exchange 2003 100% in cloud MX to Office 365 O365 outbound routed to Internet Average 20% increase in their Internet utilization at central office Some remote offices had to upgrade circuits WAN or Internet depending on location HQ in Australia had to double their bandwidth from 10Mbps to 20Mbps

Other customers reviewed On average, customers see a 20% increase in Internet utilization 2.5% on the low end 28% on the high end Remote offices that had local Exchange are the hardest hit User driven PST import and synching large SPO document libraries can have significant impact Customers not performing MRS moves saw significant impacts on the days after migrations with OST downloads

In the real world Customers will always want to know the exact impact Office 365 will have on their network But they will not have a good understanding of their current network Few if any tools to evaluate No baselines for calculators Increasing bandwidth is both extremely expensive and time consuming ISP lead times Hardware upgrades

Best practices

Preferred practices Start with headroom on all circuits Get to pilot as quickly as you can and use it to predict velocity Follow the conservation recommendations Locate DNS and Internet egress as close to clients as you can Reduce redundant hops and extra latency For Exchange customers, always push Hybrid Coex If pressed, use 20% as a starting point

Bandwidth planning recommendations Plan for growth Consider lower CIR with higher burst Spread migrations Cutover MX Outlook 2013 SP1 Pilot Lync audio and video Internet egress and DNS

Bandwidth conservation strategies Remote offices Spread migrations Internet filtering Use split-tunneling for VPN Use modern clients in cached mode or use OWA Move files to SharePoint Online Use the 50GB mailboxes, not the archives Do not rebuild profiles unnecessarily Limit/prevent PST uploads by users Use Lync Online -csconferencingpolicy
