Windows 10: Thunderbird stopped getting my emails

All of a sudden, Thunderbird version 73.0b1 (32-bit) has stopped getting one of my email accounts emails.
I have 2 email accounts through Comcast. One works through Thunderbird, the other just stopped working.
I just noticed this and I'm not sure if it started when I did an update for Thunderbird. I think it started about 6 days ago but I just noticed it.

I can log onto my Comcast account and see the emails there that don't show up in Thunderbird, I can delete them while I'm in my Comcast email settings and they do show up in the Thunderbird Trash folder. I can move emails from the Comcast web site email inbox to another folder under my main email account and when I go to Thunderbird, the emails are in that folder. I can send emails from my main email account, either through Comcast or Thunderbird, and the emails are in the Sent folder in Thunderbird.

I can send emails from this main account while in Thunderbird to my secondary Comcast email account, reply back to the main account but Thunderbird doesn't retrieve them (if that's the right word to use here). They don't show up in my Inbox for my main email account.

I don't get it. Why can I do everything with 2 email accounts in Thunderbird except the main email account won't get the emails in the Inbox?!? But when i do just about everything from my Comcast email web site, everything shows up in the required folders: Trash, Sent, Other folders??

None of the settings have changed. Both accounts have the same settings/servers/imap number, etc....

Can anyone shed some thoughts as to what might have happened or how I can fix this?!?

**UPDATE**
Even though Comcast wouldn't own up to it it seems they were having problems on their end. After I called them up and didn't get anywhere with tech support and they told me to uninstall Thunderbird, as soon as I ended the chat, I lost all Internet, everything. I tried unplugging my Modem and router to do a reset but that didn't work.
I ended up calling Comcast and through their automated service, I told them I was having internet issues. They did a modem reset from their end and now it's working again: my internet is working and so is Thunderbird retrieving my email!
Tends me to believe the problem WAS on their end after all....no?

Thunderbird Mail Disappearing

Ok so this may or may not be the right area for this, but I wasn't really about to find a place for it and it is kind of network related.

So I have a client of mine that worked for a real estate company, and was about to leave the company, and wanted to keep his emails. So I downloaded Thunderbird, and saved all the emails for offline mode, and while I was there verified that without an active internet connection that the emails were still within thunderbird and completely accessible.

He called today, saying that his emails aren't showing up in thunderbird. I remotely connected to his computer to investigate and somehow, the emails were no longer in offline storage, they were gone completely. We were both aware that within 24 hours of him leaving the place of business that his email account was going to be deleted and once deleted he could no longer receive new emails from that email and would only be able to access the ones that we saved offline. I have no clue where the emails went, some of them are listed in the %appdata% roaming folder for thunderbird, but none of them are appearing in thunderbird and I can't open the file for the emails or the .msf folder files in thunderbird to get access to them. When I try to it just attaches it to an email and tries to send it.

I'm at a loss, hopefully you guys have some answer to this problem, whether it be hack the email server to get them back, or some sly way to open .msf folders(all the emails are in %appdata% roaming for thunderbird), but I can't think of anything. Please help and many thanks
