Mailbox quotas

February 10 2005

A friend of mine just went through a Notes/Domino to Outlook/Exchange migration, as a result of an acquisition.  In the old Notes environment -- no mailbox quotas, and a 1.2 GB mailbox.  In the new Exchange environment -- a 40 megabyte mailbox quota.  This isn't the record, though -- I met with one Exchange shop where they had 10 megabyte mailbox quotas.

During one of my Lotusphere sessions (or was it both?), I asked the audience about how many had Domino mailbox quotas above 200 MB per user...about half the hands went up.  Then, how many have 500 MB mailbox quotas.... still about 20-30% of the hands.  Then, how many have no mailbox quotas -- a new 10-15% of the hands went up.

While there are counterpoints on either side, it is far more common to find draconian mailbox quotas in the Exchange world than the Domino world.  Why?  The single instance store, of course.  It just gets too big too quickly if users are allowed to store too much.  And (he says sarcastically) why would users want to actually store knowledge and information?  

It would be an interesting productivity study to sample 50 Exchange shops and 50 Domino shops around this.  What is the productivity impact of the typical Exchange/Outlook environment, where users are constantly having to download mail to PST files and manage all that corporate knowledge in risky local hard drives?  How does that differ in the typical Domino world, where mailboxes are larger and the tools for enterprise-level archiving (in Domino as well as third-party applications) more sophisticated?  And how many organizations have implemented a tool like we do at IBM, where large attachments can be moved to shared Notes databases automatically, rather than sit taking up space in individual mailboxes?

This is one of those areas where the differences between the two product worlds are stark.  It's not about having a particular feature -- it's about architecture.
