Cannot open outlook

When I open outlook it prompts me if I want to open in safe mode, If I click NO then it just closes, if I click YES, I get something is wrong with one of your data files… with the option to repair the file. I did the repair, but the same happens when I try to open outlook again.

In the event viewer, I see an outlook error event ID 2000 and right after this error, I see another outlook error event ID 2000

I attached the log file from the file repair.

Windows 10
Outlook 2016

Move your data files to a safe place, open Outlook in Safe mode and make a new Email file (from some email account). When done, close Outlook and see if it opens normally.

Try to open outlook in online mode, so disable cache and see if it open correctly. If it opens correctly in non-cache (online) mode I would suggest you delete the old ost file or if you don't want to delete it you can rename it to something like file.ost.old and then recreate your outlook profile. To turn off cache mode view the following link:

This is very common issue when the ost got corrupt. is there is nothing but cache of your emails on local system. just move or rename the ost file , once you open Outlook it will create new one and get you emails downloaded.

secondly you can try repairing the ost file by scanost.exe  based on version of Outlook location for this exe differs. scanost is Microsoft tool to fix ost file usually available in program location itself.

I hope this helps to understand better rest answer are already given above.

The file is a pst file.
What I was able to do, I removed this email data file (1), and opened it with another email data file (2) (outlook receives emails from to email accounts) but as soon I add the data file (1)  outlook crashes
I repaired the file (1) with outlook recovery tool www.oemailrecovery.com but seems to be a waste of money

Instead of paying for that you can use Microsoft free tool scanpst.exe which is already installed when you installed outlook. See below link for instructions on using that tools to repair the pst file.

May I cross out the option that dd-ins causes the issue since outlook opens fine with file (2) when file (1) is removed?

well if the pst is the issue and scanpst.exe doesnt repair it you may need to just scrap that pst or try to repair with 3rd party app.

Hello Abraham,

According to the log file attached along with the query, I am suggesting you a blog to understand the issue in detail.
Refer: https://www.systoolsgroup.com/updates/resolve-attempting-to-validate-bbt-refcounts-outlook-error/

This blog discuss the same error that appeared in your log file. This indicates that ScanPST.exe has failed in repair your PST files, since it is highly corrupted. The best solution is to go for a trustable third party application because traditional manual solutions cannot fix this issue efficiently. It may result in data loss.

I recommend SysTools Outlook PST Recovery Software. You can try the free demo edition of the software, it can repair and recover severely corrupted PST file data. And you preview all data items in the preview panel. But the demo edition only provides provision to export 25 items per folder.

Purchase the application, if you find reliable. Visit the website for information: https://www.systoolsgroup.com/outlook-recovery.html

Feel free to ask, if you are having further doubts.
Regards,
Clark Kent

Check and see if this key exists - HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\Software\Microsoft\Office\16.0\Outlook\resiliency - and delete it if it does.

* Backup the key before delete it.

did you repair office, as i suggested?

I closed outlook and reopened it I am getting the mag that the file need to be repaired.

Try completely uninstalling Office, restarting, and then install Office again and patch fully.

Try a new, test Window User Profile (Account).  Log into the new Windows Account, set up Outlook as you did above and test.

The problem is not the file since I have a good pst file from a earlier data I now use to make copies from and as said this files the first time open fine only after I close it and reopen I have the issue.
Update
I noticed I windows refresh on the desktop so I tried to open outlook and it opened no issue, What can this be?
In the event viewer I see as said event 1000 and 2000 can this be a add in that causes the issue
0
JohnBusiness Consultant (Owner)Commented:
This appears (from earlier posts) to be Outlook 2016 and there was a fairly recent update to Office 2016 (last week) and you may have just done the update, so that may have affected the ability to open.

Abraham DeutschIT professionalAuthor Commented:
Now I did it manually closed opened error, closed on desktop I did a refresh open no issue

JohnBusiness Consultant (Owner)Commented:
So an update appears to have helped

so that may have affected the ability to open.
How do I solve this?

JohnBusiness Consultant (Owner)Commented:
I got the impression above that Office had updated. If not, what do you mean by refresh
0
Abraham DeutschIT professionalAuthor Commented:
Not a update a windows refresh
Meaning if I close and open outlook I get the error msg but if I do on the desktop refresh it opens no issue

Yes, so as opposed to doing this each time, try the new Windows Account.

Abraham DeutschIT professionalAuthor Commented:
Just to clarify, I am already using a new profile I created today, and last week I created many new profiles every time I changed pst file I created a new profile

JohnBusiness Consultant (Owner)Commented:
I am not sure what is wrong, but at this point, you may have to consider backing up and reinstalling Windows. If you are sure it is not the PST file, the only thing left is Windows itself in this case
