Increase Office 365 Mailbox Size using PowerShell So, what are options to increase Office 365 mailbox size to 100 GB without upgrading the license? Well, here we have an ultimate solution that allows you to increase Office 365 mailbox size from 50 GB to 100 GB. Also, not every user wants to invest in upgrading the plan due to higher costs. But, deleting data is not always an option for many.

Thus, when the mailbox size of your mailboxes exceeds 50 GB, the organization has only two options left – either upgrade the Office 365 subscription or delete data from the mailbox. Business and Enterprise users get more space, and personal users get a little bit lower. The default size of the single mailbox is also different in the variety of plans.

The Microsoft 365 subscription plans vary in their price and given benefits.
