Exchange 2013/2016 on-premise for all students and staff at a large university here.
Our default user quota is 3Gb (2.9Gb warning / 3Gb no send / 4Gb no receive). Users may request additional storage in 2Gb increments up to 11Gb (10.9 / 11 / 12). When they hit the 7Gb mark we setup an 50Gb Exchange online archive for them automatically. We require most users to setup Outlook in cached mode and encourage them to have all mailbox items cached (rather than just 12 months which is the default). The drivers for our numbers are 1) Outlook performance with large OST files; 2) Many departments and individual users run systems that should have been decommissioned long ago; 3) Small SSDs in some devices are better used for things other than cached email; and 4) we got tired of working with people who have jumbo mailboxes and tried to pull everything to their tablet/mobile device. We are planning on moving to O365 at the end of the year. Once there we will probably give everyone a large archive and set the default quota to something small (5Gb is the number I hear the most) and not even offer primary mailbox expansion requests. For backups we use 'Exchange Native Protection Mode' which is essentially 'no backups, lots of copies'. We currently keep 4 copies of each mailbox in two different data centers, and our design would permit us to actually spread across four data centers with only IP address and HLB/GSLB changes. We lag the transaction logs 48 hours on one copy. I currently have 60,000 mailboxes and 600T of disk in the environment. /jim ----- James Rupprecht IT Architect, Enterprise Systems KU Information Technology Skype/Email: jimruppre...@ku.edu<mailto:jimruppre...@ku.edu> From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Carol Fee Sent: Tuesday, April 18, 2017 12:08 PM To: exchange@lists.myitforum.com Subject: [Exchange] Exchange User Mailbox Size Limits I'm curious to know what/if any user mailbox size limits people are setting these days. So .... My questions are Are you using Exchange on premise/Azure/Office 365 ? (We are Exchange on prem) Do you use an archiving solution for your Exchange mailboxes ? (We are using Barracuda Message Archiver) If so, what is archived ? (We automatically archive nightly anything >50kb) What have you set for size limits on your Exchange mailboxes ? Thanks in advance. ________________________________ Carol Fee Network Administrator 617-338-0623 c...@massbar.org<mailto:c...@massbar.org> [mbalogo-gold] Massachusetts Bar Association 20 West Street Boston, MA 02111-1204 (617) 338-0500
