I've outlined in red things that have changed. however, all emails were displaying in order of who they were sent to, rather than who I tried saving that view as a new view, then applying it to the Inbox, which got me close to what I wanted. The view in my Sent folder is what I'd like the Inbox to be. I tried resetting the view, but that changed it to something other than what it used to be.

If you used the All Mail Folder and want to continue to use it without doubling your ost-/pst-file, you can create a “All Mail” Search Folder as an alternative All Mail Folder Search Folder alternative Note 3: Outlook will also automatically compact ost-files and pst-files when it is left open and the computer is idle for a a while. For more info about running Compact Now also see: Shrink pst-file after cleanup with Compact Now. You might want to consider running this process overnight instead. Note 2: Depending on the size of your ost-/pst-file and the speed of your disk, the compacting process could take quite a while, could slow down your computer and block access to Outlook.

This is because the file also includes hidden items such as indexes, rules, views, forms, quick steps and other meta data). Note 1: Even after compacting your ost-/pst-file, it could still be 25% or even up to 40% larger than the reported mailbox size in Outlook.

Now that you have unsubscribed from the All Mail folder, you can force Outlook to directly compact the pst-file or ost-file so that the size of the pst-file will be reduced and free space is returned to your disk. Other than trying to limit the amount of Labels you assign to a single messages or changing your sorting method, there isn’t a true workaround for this. This is because these Labels are converted into Folders when connecting via IMAP. When you assign multiple labels to a single message in Gmail, then this message will also be downloaded and saved multiple times once for each label Unsubscribe from the All Mail folder to remove duplicate content and make the pst-file smaller.

To reduce the size, unsubscribe from the “All Mail” folder and run Compact Now for your account. This will basically duplicate all mails and also double the mailbox size. When you configure your Gmail account via IMAP, you’ll also find an “All Mail” folder in the root folder which lists all your messages again, regardless which folder they are in. Why is there such a huge difference and how can I reduce the amount of space the pst-file takes on my disk? However, my mailbox size reported in Outlook is 15GB and my pst-file is 19GB.

My mailbox size as reported in Gmail is 7.3GB.
