This function is wildly broken. I had to remove my profile and add it again because indexing broke and I couldn't search any of my emails - which is also the only workaround to fix that problem - only to find Outlook now has a wildly stripped down version of IMAP integration with Gmail.
Since Office has moved to a subscription model, I'm finding it harder and harder to justify using this suite of products when the dev team seems to be actively working against its user base. I oversee multiple projects at a time and need to be able to organize all materials and communications. The fact I can't make a simple folder makes Outlook pointless.
