Xfinity Email Folders out of sync with Outlook

I have been using Outlook to manage my emails for years. I am currently using Outlook as part of MS Office 2013 ... obviously out-of-date, but that is another story! The good news is that I am able to receive NEW email in Outlook. In fact, my Inbox on Xfinity is in agreement with my Inbox on Outlook. The problem is that not all folders in Xfinity Email are in sync with Outlook. I would like to get my email in-sync so I can migrate to Thunderbird. 

Over time, I have used Outlook to add and delete email, and have also updated folders (added, deleted, renamed, moved, etc.). The odd thing is that some changes made in Outlook are reflected in Xfinity Email but others are not. One of my primary frustrations is that folders that have been deleted in Outlook are not deleted in Xfinity. In addition, some folders that have been deleted in Outlook are grayed out in Xfinity. Another core issue is that some folders added (or moved) in Outlook are nowhere to be found in Xfinity Mail.

Xfinity Email settings have all boxes checked, including access through third-party programs such as Outlook. 

Outlook Account Settings show Account Type: IMAP; Incoming mail server: imap.comcast.net; Outgoing mail server: smtp.comcast.net. 

Thanks in advance for your help in getting my Outlook in-sync with Xfinity Mail in preparation for migration to Thunderbird.

Thanks for reaching out to us I do apologize for any inconvenience your experience with your third party e-mail, you may want to go back into your e-mail settings https://www.xfinity.com/support/articles/third-party-email-access and turn on the third party e-mail program, you may have to turn it off and back on to get it to resync up correctly

Please let me know if the solution worked. My fear is that it will use your personal folder set-up in Xfinity webmail to sync (change) your folder set up in Outlook to match what is on the Xfinity webmail. If your personal folders in outlook are set up under your comcast email, I believe that changes made in outlook are not backward compatible to Xfinity webmail. Meaning you have to manage (change, re-organize, delete, add) folders in the xfinity webmail (ie on the xfinity server) which in turn will pass through the same folder structure to outlook?

I am using Outlook (that came with Microsoft Office) on my PC.  Like the original poster, I have lots of folders set up.  And over time I have renamed, added and deleted folders.  The issue is when I delete a folder on my PC, it mirrors this change across my Xfinity webmail, iPad and iPhone.  However, those deleted folders keep appearing back in the Trash folder on my PC, but do not appear in the Trash folders in my Xfinity webmail, iPad or iPhone.  I try to empty Trash, and they reappear instantly.  And, it sends me a "Sync Issue" email each time.  So my email was filling up fast.  I adjusted the sync interval so I got less emails, but I was still getting them. I switched to a new PC, and started with a fresh install, and this same issue happens, and again, tons of "Sync Issue" emails.  Xfinity could not help, first line Microsoft Tech could not help. They set up a second tier Microsoft Tech to call, but they never did.  Blogs on the Internet all said to do the same things, and it still didn't work.  I finally searched on the error message and it said an easy fix was to recreate the folders it was looking for (the deleted folders in my Trash on the PC). So after tinkering for a while, I figured out the solution.  You first have to recreate those missing folders with subfolders on the Xfinity webmail (I used the same folder trees I saw in my Trash on the PC). Then make sure those folders show up/sync on the PC Outlook.  Make sure that all the Sync Issue emails stop.  When they stop, that means that the Xfinity side is happy.  Then you can now delete those folders on the Xfinity Webmail.  Resync on your PC (the Send/Receive option on Outlook on the PC), and check to see that the deleted folders you deleted on the Xfinity webmail now show up in your Trash on your PC's Outlook.  Now you can delete those folders, and they should stay "deleted" now.  It was a long way around, but it seems you have to do folder housekeeping (deleting) on the Xfinity webmail side first, or you will get sync issues again.  Anyway, hope this helps someone else.  This was many frustrating hours worth of troubleshooting to finally have a solution.
