Hot on the heels of the increased capacity with SkyDrive Pro Online Microsoft has just announced that Exchange Online Mailboxes will double in size. Here’s the announcement:
You’ll see that it is basically across all plans and all mailboxes, including shared mailboxes.
Existing users won’t need to do anything, their mailbox will automatically increase sometime between now and November.
This is yet further evidence to my mind of how fast Microsoft is bringing improvements to Office 365 so expect to see further updates coming thick and fast.
