Outlook Error

Hi,


 I have an error when trying to open Outlook. I have several email accounts along with one gmail account. I tried Safe Mode, Quick Repair, Online Repair, Microsoft Support and Recovery Assistant. But none of that was helpful.

The only thing that I have not tried is repairing mailboxes using SCANPST.

How do I know which account is causing this problem?

Do I run SCANPST on all OST files?


What suggestions do you have?


I have created a new Outlook profile for all other email accounts except GMAIL account becuase I don't have password for it. 

That is the reaon why I am interested in seeing Outlook open in the original profile. 


Thanks.

"Do I run SCANPST on all OST files? ": generally, no.  OST files are temporary files.  You should be able to delete them (better yet, rename them) and they'll get recreated by the host where the emails are actually stored.

what is causing this error?
renaming these ost files one file at a time is the way to go?

@CompProbSolv,
It worked.
I just picked a very first OST file in C:\Users\%username%\AppData\Local\Microsoft\Outlook folder, renamed it to xxx_old.ost like you suggested and started Outlook.

Thank you for your insight!

You are welcome.  That's a pretty standard solution for problems with OST files.  How big is your largest OST file?

About 5 GB.

That's not hitting any limits, but is still somewhat large.  Consider archiving and backing up old emails.

I also advise clients to look at large email messages (ones with attachments) and see if they really need to be kept in email.  Most of the time the attachments have been saved elsewhere.  If so, the message likely can be safely deleted.
