We have a Small Business Server 2003 with only about 30 users and have some users mailboxes that are close to the default mailbox limit of about 2GB (about 12 users) and it’s difficult to get them to delete enough email as they say they need to keep some old email for a while in case they need it.
Im aware that’s its possible to increase the default mailbox size limit but im not sure if this is such a good idea as already some users are reporting it seems to take longer to sync there email with the server (we use cached exchange mode) than usual.
Also I’m concerned mailboxes might more easily become corrupt if I increase the default mailbox size.
I thought about implementing an email archiving solution such as webroots web based service which automatically archives all incoming and outgoing email. However we don’t really want to have to pay a yearly fee to use this service. I’ve tried archiving email using .pst files but these can become corrupt and when a user requests to view some old email its not so easy for them to do. Alternatively I thought we could consider migrating to server 2008 with exchange 2007 as I believe the default mailbox limits are higher in exchange 2007? I believe about 10GB – is this correct? But I’m not sure if it’s actually currently worth us investing in a new server just for this.
Any help/comments on if we should just increase the default mailbox size limit on the SBS 2003 and it should be ok without casing any issues or if we should instead consider getting a new server with exchange 2007 would be appreciated. Or any other alternative solutions you would recommend?
