Finding the size of my mailbox in Outlook for Mac (Office 365)

I am running Office 365 on my iMac and trying to find out the size of my mailbox but don't seem to be able to find a solution in the Outlook Help or the MS communities.

Has anyone come across this and have a solution.

I am running version 16.53.

Thanks

iMac 21.5″ 4K, macOS 10.15

Go to this folder:

/Users/username/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles

The size of that last folder is the total amount of space emails and their attachments are taking up on your drive.

Thanks but what I am looking for is how much space my mailbox is currently using up and which folders are contributing most to the size. It used to be as simple as right clicking on it and looking at properties but for some reason this is not available where the mailbox is local rather than online.

I think it's like most any other office type products, it's as large as available disk space for locally saved data and/or limitations set as part of your Microsoft 365 agreement.

I haven't used Outlook in years, but best I recall, nothing is unlimited and the amount of storage space is determined by what plan you bought into. The same approach OneDrive takes: a very restricted amount of space until you buy more.

Check your license and/or the full agreement you agreed to. It's there somewhere.

I did find this with a quick DuckDuckGo search: Storage limits in Outlook.com (microsoft.com)
