I am setting a new Windows 10 Pro computer with Outlook 2016, and I am trying to connect/setup their Gmail mailbox. On the original old computer with Outlook 2010 or 2013 they setup it up connecting to the gmail mailbox via POP. It also appears they have many mailbox subfolders within Outlook on this computer. However, when I setup the new computer I cannot seem to see most all the mailbox subfolders that are visible on the old computer. When I logon to the gmail mailbox direct (browser) I cannot see the missing folders that exist in the old computer's Outlook either.
I also changed the gmail mailbox settings disabling POP and enabling IMAP. So I can connect to the mailbox via Outlook but many subfolders are missing as mentioned above. Also, If I create a new mailbox subfolder within Outlook I cannot see it in gmail direct (browser). If I create a new mailbox folder (label) within Gmail, it does sync/display within Outlook.
I am thinking all the Outlook mailbox subfolders created on the old computer were only created within Outlook since it was setup as POP and IMAP, so that is why they are not working/syncing. Just taking a guess here. However, now that I changed the gmail settings to IMAP I can't seem to sync newly created folder either. Pretty weird scenario. I would think if I create a mailbox subfolder titled "test" within Outlook it should be created within gmail itself or vise versa.
So we have multiple problems getting gmail working on a new computer with Outlook 2016. One, the existing Outlook mailbox subfolders do not appear within the Gmail mailbox. Two, now that the gmail account is setup to use IMAP, new subfolders created within Outlook do appear in gmail or vise versa.
