Since Outlook is being a bitch...
 

What e mail clients do you use that are free to handle multiple pop accounts?

Thunderbird

What issues are you having with Outlook?

This!!
Unless you're on a mac in which case "mail" is a very good option too.

Maybe I'm behind the times, but I have multiple e mail addy's bc. of diff. websites I run. I use software to help me organize all the mail coming in.

outlook 2013 ...you can buy outlook standalone from Microsoft...

yes, and I use my own email server also...I need all my emails in a searchable location so I can search when I need to, I also keep all my emails and my responses.

From the thread title I'd say OP wants something ELSE.
He also said "free". :2 cents:

all you ballers and looking for free...don't even try it...spend some of that big money

Dumped Outlook got Thunderbird been pretty happy

Thunderbird for work. Gmail for personal.

I will second that! Thunderbird has worked like a champ for me for years.

Or a crack for office in Windows 10 would also work. :P

tbird...

Outlook 2007,2013 or whatever. Backup,search,rules,filters,auto sorting,calendars,reminders,contacts,categories,ev ernote intgration....

ThunderBird and FoxMail are free but spend $15 and get PostBox. You won't regret it.
