Exchange 2010, 2013 and 2016 maximum mailbox size

Question

Which is the maximum size limit for a single mailbox in exchange 2010, 2013 and 2016?

Solution 1

The default limit is 2gb. However the only limit will be the physical limit of the database, which is 2TB.

However a mailbox of that size will be almost impossible to view. The practical limit would be somewhere between 30 and 60gb, depending on the Outlook version being used.

Where did you get this number from? It's completely wrong. You might be thinking of the maximum file size for an ANSI format PST file.
