Ooooooo... a can of worms! Our default for most users is PSAR at 160MB Our "special" people get PSARs somewhere between 200MB and 500MB - the higher levels mostly to Marketing and Real Estate folks who can't get their vendors to use sftp for ridiculously large graphic and CAD files. That being said, we have a 20MB limit on incoming mail. We have one exec who is capped at 1.5GB and another at 2GB (20,000 and 28,000 items respectively). The justification for increasing the mailbox limit is usually "if my mailbox fills up I'll miss important email". So you increase it again, it fills up, increase, it fills, rinse, repeat, rinse...
We currently have a group of users using Exchange Personal Archives with Retention Policies and Tags. These currently have no limits on them which is doing a great job of proving that the more space you give a user the more "stuff" they will put in there. Case in point with the mailbox limits. It also proves that users will put the longest retention tag on everything they keep. The other users are still using PSTs for now, which would be migrated into Personal Archives if we continue to move that direction. And we're talking terabytes in that alone. The main issue here isn't the storage. I could easily throw terabytes at the servers to accommodate. The issue is backup and recovery. I know, I know, we've been told that if we're running a DAG that tape backups are necessarily needed but tape backup is part of our DR strategy. The problem is if you're going to back up your mailbox databases it has to go somewhere, whether on tape or disk-to-disk. We could backup to the cloud but there is an expense to that as well. And it's hard to impose quotas on mailboxes without the users pointing to Google mail and saying "They give me 15GB!!! Why can't we have 15GB???" The fact is that Google has the resources to backup and restore that kind of data. Good luck!

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 [email protected]<mailto:[email protected]> [cid:[email protected]] Massachusetts Bar Association 20 West Street Boston, MA 02111-1204 (617) 338-0500
