I’m sure we can all agree that setting global client side mailbox limit’s in Exchange 2007 is a straight forward task to perform. However, I have recently identified on several deployments still running Service Pack 1 that when setting client side limits on a mailbox database, they fail to apply correctly. While this should be a instant change, in some cases the change does not apply at all. To save hours of searching around for a limit you think you might have missed, performing the following will temporarily resolve the issue:
1. Click Start and select Run
2. In the Run dialog box type services.msc
3. In the Services console locate the Microsoft Exchange Information Store service, right click it and select restart. Please note that restarting this service will temporarily dismount your mailbox and public folder databases.
4. Close and reopen Outlook / OWA and the limit warning will no longer be visible.
To completely resolve this issue it is recommended that Exchange Service Pack 2 is applied. I would also recommend applying any outstanding rollup updates, at the time of this entry Rollup Update 4 is the latest release. See below for direct links to these updates.
