Outlook 2010 duplicate download emails 1 inbox 1 PST no updates

Been using Outlook 2010 for ages, admit that my inboxes on both the server and in outlook profile contain many emails. I need to keep emails still on the server.
Starting yesterday , with no update from outlook software since June 2017, my inbox started downloading all the emails on the server's inbox. Before that, it only downloaded emails that hadn't yet been downloaded.
I only have one email address, one inbox, one outlook profile. I don't understand what changed.
Can you explain? Why did it suddenly change?
I understand some workarounds- on the server, move emails out of the inbox after I see them there (ie create a Read mail box?) I have never sync'd to my phone (where I use the emails on the server) because I KEEP ALOT OF EMAILS on my computer and have space issues.
My pst file is quite big, as is my archive.
Can someone explain why it changed, and what are my options?
Also, what is the the method for adding modify date to outlook 2010 so if I want to delete the 600 emails that have come in twice in the last two days, I can do it more easily? (that's the number in my 100 day keep on my server setting).
Thanks for any help.

It can be one of two things:
1. something caused the message manager file that tracks the last downloaded item # to be corrupt or deleted. Scanpst, exporting to a new pst, using it in a second profile are all potential causes. oh, and an antivirus that scans the pst can corrupt it too.

2. the server renumbered the messages in the mailbox, confusing outlook so it started over. This should only happen if there was a problem with the server and the host "did something" to fix it - its not a normal occurence.

You can remove the duplicates manually since they all should have the same last modified time - instructions are here:
Duplicate Remover Tools - if outlook is set to delete mail from the server when you delete it in outlook, move the mail to a new pst then close the pst and delete the pst.

if it happens frequently, you can use a rule to move mail that was received before 'today' to a new folder but it only works if the rule is set up before the mail is downloaded. The rule can stay in outlook - if it happens again, you'll have fewer dupes to deal with as ones received before the date in the rule will be handled by the rule. (RE outlook's delete settings: Move the folder to a new pst after the mail is downloaded then delete the pst.)

Thank you for the quick and knowledgable response! I easily removed the duplicates by using the modified date field. I decided to set up a new rule (never did that before) and in choosing the date, when the calendar opened, I selected the word "TODAY" at the bottom of the calendar. I assume that date will change daily, is that correct? I've created a new folder called mail received before today. I imagine that if I don't have access to outlook for a bit, emails received over the past few days will accumulate there, is that correct? But I can easily move them elsewhere.
Thank you again for your help. Appreciate these final clarifications.

i think it is hard coded to the date you created it - so "today, September 15 2017". But you can verify tomorrow. :) Even if it doesn't update, if the problem happens again, much of the older mail will be filtered out.
