I manage the exchange system for investment research analysts. I have set a mailbox size limit to 200 meg, and i have users filling that up in a week.

I guess my question is: Does anybody else have this problem? I am trying to get an 'industry standard' to show management that we are either in line or above limits imposed on other firms.

I am especially interested in limits for other investment reseach firms.

Thanks in advance.

I work for a large financial services firm and we use 20MB limits, 50 for VP's, and Senior VP's and above can pretty much do what they want. What you should do depends on your hardware and backup stategies more than anything. But might I suggest teaching the users to use PST's, set up rules, clean their deleted and sent items regularly.

My research analysts routinly get emails with 5+ meg attachmetns, so that would mean 4 or so emails before they hit the limit. How do you deal with that?

I have instituted PST usage, and am rolling out profiles that automatically select 'Empty deleted items when exiting.

Do not think of this as an Industry limit but more like an Organization/Server limit. If your Exchange server is "Standard edition", then the Information Store is limited to 16GB. "Enterprise edition" is limited only by the server's hardware. You need to create a logical equation that best fits your needs, current limits, and future requirements.
EXAMPLE: 20GB Hard Drive / 100 users x 1.5 for future growth + keep minimum 500MB free space = 130MB
However, if my backup can only support 15GB of data in 1 shot without human intervention, then I would use 100MB per person. Also, management likes to have higher numbers than the workers so keep that in mind as well.
Limiting the mailbox is for you to determine.

My firm is in the Benefits industry - currently have 80 users with 20% growth rate/year. Each user has a 10 MB limit with 2 MB attachment limits (in & outbound mail) - I instituted .PSTs and "Empty Deleted Items upon exiting" Outlook as well.

Per the previous post, VPs/Managers have a 20 MB limit with 4 MB attachment limits w/ 'upper' management (my team of course) with no limits.

NOTE: I know of firms out there that limit mailboxes to 10 MB for EVERYONE (financial services firm) and 1 MB limits on attachments.

Rule of thumb: If you are running out of disk space on your mail server or backups are failing because you have email hogs, limit their mailbox and institute .PSTs ASAP.

My two cents. . .

My company has no limits, consequentially, we have an 80GB Private Store, some individuals have mailboxes over 3GB in size. Oh for the support of management to put in some limits!

We use a CleanMail! It cleans out messages and moves or deletes attachments. Each user sets up their own schedule. Extremely cheap remedy per mailbox. http://www.MADSolutions.com

I'm the Exchange admin for an investment bank. We have 50 MB standard limit, with 100 extended limit for executives. Have all clients that do not use it disable journaling, set autoarchives (not just PSTs)to a very strick occurance, continually remove old/obsolete mailboxes, and perform offline info store defrags as often as you can allow (look for 1221 in the application event log for fragmentation size). Of course, your backup strategy/hardware config are very important factors in optimal mailbox size settings.

I've currently got mine set to 300MB per user, with about 75 users.

The last four users, in size order, take 296, 353, 379, and 538MB of space.

I guess the last three users are ignoring the warnings.

The entire message store is about 5.5GB. This is on a 16GB partition.

Justin, you might want to have those users over 2GB trim their mailboxes down... there are posted KB articles about issues with PSTs/OSTs that are over 2GB and database corruptions.
