email client

I have Windows 10 pro and have been using Windows Mail; unfortunately it is erratic syncing and I just lost a valuable folder. It seems ok at times and I like its simplicity because I am at an average tech level.
I have had other issues with it so have discontinued use.
Awkward as it may sound, I use gmail because of my phone but it too has difficult folders.
I have a MS account because I run Windows and it too has fickle folders.
So I use the folders in my ISP Comcast account as it is dependable as far as folders go.
All of my contacts and places like forums and doctors tetc have my MS account as the default.
I have read about email clients and tried a few like Thunderbird, Claws, and another that escapes me.
I need an email client that is fairly easy to use and can accomodate three accounts.
Are you aware of any? I don't have a VM so don't want to try then remove too many.

OK, this is just my $0.02 worth. If you liked the old M/S Outlook Express you may want to look at OE Classic from here: http://https://www.oeclassic.com/ A member here suggested it to me and I switched. Works great with my gmail without having to go to gmail.

I really appreciate your kind reply but when I clicked the link it said this site cannot be reached.
So I used Edge instead of Chrome and the same thing occurred. I checked my firewall and have no barriers up I can think of.
I allowed my Adguard Adblocker to let it go through too.

The link is bungled, just copy the part of it:

This worked for me just now:
OE Classic - Easy to use Outlook Express replacement

This am Berton's link worked for me with Chrome. It seems to be what I need but I noticed 'free/paid' on the bottom. Will I get the features needed with free and not be on trial or bothered to pay? I also wonder how I will know when it is no longer supported.
Thank you for this referral and I look forward to your reply.

Do you have an opinion about Mailbird? It seems to read well and it will be one or the other.

Haven't yet tried Mailbird but will be later today.

Thanks;I look forward to it.
