For Gmail there is a setting in the security settings That allows other less secure apps or programs to access email accounts. Take a look at this and see if it helps you.

How to enable access for non-Google appliations to access Gmail accounts.

No where in any of my Gmail accounts is there a "Security Settings" or anywhere where I can make adjustments for "Less secure app access". I do remember this from Outlook 2003.

 

Hello,

I just realize there was a little bit of confusion in the instructions. The particular setting I was referring to is not located in the Gmail settings as they originally described on the article I posted. You have to go into your Google profile that is the administrator level Account for Google. What I mean is if there was an originating google account and then you subsequently created other Gmail accounts you need to go into that originating Google profile and then there will be security settings in that profile that covers a variety of Google apps that are associated with the main Google account not just the Gmail account. Here is a picture of what mine looks like. You will see on the left side that there is an item for security. The picture I am showing you is what is available in that security setting.

The .ost file is an Offline Outlook Data file, it is created when you import an Email account to Outlook, as opposed to the .pst file which has all the settings for your online Email accounts. Introduction to Outlook Data Files (.pst and .ost) - Microsoft Support

Can you open your browser and login to each Gmail account separately not using Outlook? Signing out from each one before going to the next one? You want to test this first to make sure all Gmail accounts are working correctly before importing them to Outlook.

Thank you.

Over the last 10 or so days, I have logged-in to each of the 3 accounts in probably every order variation there is.

Note: I just turned 2-step verifiction off in one of the accounts and Outlook still did not connect.

Also, every time I start Outlook now, at least 3 .ost files are created. More if I try to set a new connection.

 

That is correct. Offline storage .ost file is created for each account you create in Outlook.
If you can login to each Gmail account online in your browser, then there is no problem with the Gmail account, if not, then there is an issue with the Gmail account and it will never load into Outlook. As a side note, if you can't load the account into Outlook, but can access it online in your browser then that account is still accessible, you may have to access that account in your browser rather then Outlook for now.

 

Based on all of my failed tries, I agree. The is nothing wrong with Gmail. The problem is with Outlook. The only option with Outlook would be to access the accounts with my browser which begs the question: Why do I need Outlook?

Looks like tomorrow I will look at replacing Outlook with Thunderbird.

Thank you for your attention.

 

C:\Users\(me)\AppData\Local\Microsoft\Outlook this is usually the Default location of the.pst file, but it can also be C:\Users\(me)\Outlook. You go to Search and type *.pst or *,ost to find all of these files on the computer.
Here is a way to manage your ,pst files.

I found all the .pst and .ost files. I've tried removing all the files associated with 2 (out of 3) accounts that will not connect. I've tried removing all instances of each (individually and together). This morning, I put the files in the 2 locations mentioned (Note: C:\Users\(me)\AppData\Local\Microsoft\Outlook and C:\Users\(me)\AppData\Local\Outlook and C:\Documents\Outlook Files).

Outlook will NOT connect to either of the 2 accounts, by any of the methods offered by Outlook 365.

Thunderbird connected to all 3 accounts in something less than 5 seconds.

Everything worked until about 2+ weeks ago.

While I would prefer to have a working Outlook I will settle for Thunderbird if I can import my .pst files.

All I ever get is "Something went wrong". See attached.

Note: I am not addicted to a cell phone and prefer to get my email on my desktop,.where I work in my retirement.

Thank you for your suggestions and I am sorry to take up your time.

Thank you again but nothing here helped.

Thunderbird is downloading my mail, so yes it is a partial solution. I would like to transfer my Contacts/Address book, calendar, and other data to Thunderbird. Since I do have backups of my .pst and .ost files, I'm going to look into re-loading Outlook.

Heres a solution that worked for me

1) go to control panel and then mail
2) click show profiles
3) click add and insert the name of your profile
4) click ok and then dont enter your email. Just click cancel and ok to close the prompt msg
5) then down on the "Always use this profile" select your new profile instead of Outlook"
6) click apply and ok
7) now open outlook and add your account

P.S it seems that this will just let you use your new account but wont be able to add any older you used

Best wishes!
Mike

 

Thanks for the try.
Unfortunately this is in Windows 10. The is no Control Panel, I can't find any profiles or anything else in your list.

There is indeed a Control Panel. Go to Search and type Control Panel, and press Enter.

 

Wondered were Control Panel had gone. Found it and fol lowered your instructions.

Wow!

Looks like everything is working after 2 weeks!

You've made my day. I can't thank you enough.

 

You are Most Welcome

 

nonetheless this is just a workaround to add your 1 email that you most need to work with.

Adding a 2nd gmail account still isn't possible from what I have been searching. It must be a problem/bug of the outlook app. Waiting for microsoft to fix it some time soon.

peace
Mike

For what it's worth regarding transferring contacts from an old email program/client to a new email program/client, this is what I do...

Using Excel or a spreadsheet program that handles CSV files. Using the old Contact List, EXPORT the contacts to a .csv file. Rename the file old_contacts.csv. This is your current contact list but to IMPORT it into the new email program/client, the columns and headings of the spreadsheet csv need to be what it is expecting and the original one you exported will not necessarily be exactly what the new program is expecting.

To know what the new program expects and make a new reordered list that can be inported, the first step is to go to the new email program and export those contacts to a different .csv file. If the program doesn't have contacts yet, add yourself as a new contact. Then export the contact list as a csv and rename the file new_contacts.csv. If you open the new spreadsheet, you will see the spreadsheet list the way that your new email programs likes it to look - even though there may be only one line, one contact with your information.

Keep the new one open and open the old one. Now you can copy columns from the old list into the new list using spreadsheet Copy and Past skills and omitting the column names of course. Once you get the columns containing the First, Last, Email, etc copied in to the new spreadsheet, save it.

Now you have a csv file (new_contacts.csv) formatted/ordered that will work with your new email program's contact list. Now you can IMPORT this list you made.
