Microsoft Outlook 2013 has "stopped working" on Windows 10

Outlook 2013 has been running fine since clean install of Windows 10 back in July.

It started to play up a couple of weeks ago with "Not Responding" messages, closing and re opening fixed it at the time. Today it stopped working with the same error but when I re started it produced a new error "Microsoft Outlook has Stopped Working".

When I restarted it this time I got the message "Outlook couldn't start last time. Safe Mode could help you troubleshoot the problem etc..." So I start in safe mode and get a new error message "Something is wrong with one of your data files and Outlook needs to close. Outlook might be able to fix your file. Click OK to run the Inbox repair Tool.

I ran the tool on each of my five data files but Outlook continues to "Stop Working" on startup

I also moved all the data files so Outlook had to re create them but still got the "Stop Working" error

Anyone have any clues as to what i can try next?

Outlook 2013 works fine on Windows 10. I used it - now on Office 2016.

1. Try a Full Repair of Office (Control Panel, Programs and Features.
2. Run SFC /SCANNOW twice from an admin command prompt. Restart after step 2 and test.
3. Make a new, test, Windows User Profile (Account), log into the new Windows account and test Outlook in the new account.

Thanks John, it's been fine for past couple of months, really odd that it should suddenly play up...

I did the full repair/reinstall then ran the scan twice and re started the machine.

I made two new profiles: 1 with an account and one with no account and set the profiles to ask each time I start Outlook.

When I start outlook and select my original profile, I get the same errors and option to repair the data files

When I start Outlook and select the new profile with an account it all works fine

When I start outlook and select the new profile with no account it works fine.

It seems like there may be a problem with one of my original five data files even after they have all gone though the repair tool?

What you can try to do is the following:

Close Outlook.
Make a copy of a data file and name it backup.PST.  Do this for each data file except name backup1, backup2, and so on.

Move the Outlook data files out of their Outlook location. Do not delete them, just move them to a non-Outlook location. Now move the backup files into this location.

Open Outlook, and your account should make a new empty PST file. Once you know that is true and all is working, use File Open to import the mail from backupX.PST and see if it works. Continue down this road until you have restored everything.

I made the copies and renamed them then moved the originals to a new folder that I named originals just under the outlook folder (C:\Users\david\AppData\Local\Microsoft\Outlook\Originals).

I started Outlook and immediately got a message "Something is wrong with one of your data files... Click OK to run the Inbox repair tool".

This message was displayed even before Outlook asked me which profile to use (I still have them from last nights testing).

I clicked the close button rather than run the tool again and Outlook shut down so I re started it and got the Profile selection box, I selected my original profile "Outlook".

As the explorer window was still open I saw Outlook creating the five account data (.ost) files associated with this profile. Each one was named after it's account name and all were 16,424kb in size. Outlook got to the last file then failed with the message "Outlook couldn't start last time. Safe mode could help you troubleshoot the problem... Do you want to start in safe mode?"

I clicked yes and got the error message "Something is wrong with one of your data files... Click to run the inbox tool" I clicked No.

When I checked the explorer window I noticed that the Backup file sizes had changed, they were all 32,712kb except the last one "Backup5" which was 16,424kb, the one that caused the fail I guess?

If it helps, three accounts are IMAP and two are exchange at

If there are no PST files  (that was not clear at the beginning) delete the OST files (or move them to a non-Outlook location), restart and try letting Outlook rebuild the OST files

I deleted all files (.ost .log) from the outlook folder, started Outlook and selected my original (Outlook) profile. Outlook then created the five (.ost) files named after their respective accounts then presented the data file error message. Each file is 16,424kb in size.

Try Outlook in a new Windows user account as suggested above.
DavidBurchettAuthor Commented:
I created a new standard (not family) account in windows 10 (pro) and when I started Outlook it took me through the new email account setup wizard. Everything went smoothly and the account is currently populating with email's.
JohnBusiness Consultant (Owner)Commented:
So then the issue must be a Windows Profile issue.
DavidBurchettAuthor Commented:
OK thanks for your help John, should I close this now and start a new question in the Windows section?
JohnBusiness Consultant (Owner)Commented:
We know it is a profile issue and the fix is to back up the data in the problem user profile, delete the profile and make a new one, Then restore the data.

I have never seen a fix for a damaged profile other than to re-create it, so I don't think you need to ask a new question.

For this question, yes, you probably should close it because we have solved it.

Your dead right about the damaged profile, even after deleting all the old profile ost files and setting my new profile to be the default, Outlook continued to play up until I deleted the original profile completely. Happy to say it's all working again and all my email is back, I just have to go through marking spam and re creating my calendar categories but that won't take to long. Thanks again for your help...

You are very welcome and I was happy to help.
