    Microsoft increased the archive mailbox size to match the user's primary mailbox quota.

    Your E1 license gives you a 50 GB primary mailbox. Adding the Online Archive essentially gives you another 50 GB.

    Since the total is now 110 GB, the user likely had their primary mailbox quota increased to 60 GB (probably via an E3 or E5 license). The archive then automatically expanded to match it.
