How can I check the maximum size of my exchange folder/account vial Outlook 2007?
Note: I don't want current size, which is available on my mailbox properties, but the maximum that number can grow to.
If you mean the maximum size that the server has the mailbox set to in the mailbox size limit section, there is no way to determine that from Outlook.
If limits are not set on the server, then there is no maximum size. Of course you will run out of room on the mailstore partition at some point, and you might have a size limit there (Exchange 2003 standard)...
