It looks like Microsoft has increased the default mailbox size to 25 GB on a couple of our Microsoft Exchange Online accounts. I haven’t seen an announcement from Microsoft on this yet, but looking at the Microsoft Online Administration Console for our accounts, you can see the new storage quota. I’m not sure if it has been like this for a while, but I just noticed it today. I’m also unsure if this has been rolled out to everyone. Below is what is shown in MOAC.
