This answer introduced another problem with Outlook: my computer lacks .pst files.
-
4 of 5 email accounts are @outlook.com, and are listed as 'Exchange ActiveSync' under 'Type'. But these 4 are all personal accounts; they don't concern any servers or administrators.
1 is my work email, and is listed as 'IMAP/SMTP'. -
I confirm my selection to view all hidden files and folders.
-
I tried searching for .pst files with Windows Explorer, but nothing emerged.
-
I assume that Outlook ought have already created and then automatically updated .PSTs:
[Source:] Although the default install of Outlook creates a .PST file […]
- The following quote discusses 3 methods. 6 simply led me to the same folder cited in 8, which contains only .ost files. No .pst files appear.
7 led me to F:\Documents\Outlook Files
, but this was empty.
[Source:] The fastest way to open the folder where your Outlook Data File (.pst and .ost) is saved is to do the following:
[6.] I. In Outlook, click the File tab.
II. Click Account Settings, and then click Account Settings.
III. On the Data Files tab, click an entry, and then click Open Folder Location.[7.] Outlook Data Files (.pst) created by using Outlook 2013 are saved on your computer in the Documents\Outlook Files folder.
[8.] If you upgraded to Outlook 2013 on a computer that already had data files that were created in Microsoft Office Outlook 2007 or earlier, these files are saved in a different location in a hidden folder at drive:\Users\user\AppData\Local\Microsoft\Outlook.

What are .ost and.pst files?
Source Introduction to Outlook Data Files (.pst and .ost)
My computer seems to lack .pst files.
This confirms that your email is using Microsoft Exchange (in the case of your work IMAP/SMTP account). The
.ost
files are from accounts that you have set up with the Outlook Connector for Outlook.com (formerly Hotmail).The adminstrator of your work Exchange Server (in the case of your work IMAP/SMTP account) should be responsible for backing up the server (and your emails).
You might like to confirm with them that backups are actually taking place.
For the other email accounts @outlook.com then Microsoft is the administrator of 'your email server'
Do I need to backup an .ost file?
Source Create an Outlook Data File (.pst) to save your information
But I really want to backup these 4 .OST accounts
In this case you might like to backup the local
.ost
files using your normal backup program (or trust Microsoft not to mess up your accounts)You can also export your mail as a
.pst
file by following the instructions in Exporting and Importing Mailbox Content in Outlook 2013.The
.pst
file can then also be backed up using your normal backup program.The advantage of using a
.pst
file is you can then import all of your email to another computer running Outlook.Note:
If you access your email account from multiple computers or devices, it’s important to know that when messages are moved to an Outlook Data File (.pst) they are available only on the computer where the file is saved.
Clarifications as per your comments.
Microsoft Exchange can be configured to support IMAP/SMTP. It could also be some other mail server that supports IMAP/SMTP. Only your work IT department can answer this question.
You can copy and paste but it is better to use a scheduled windows backup.
Email messages will be moved if you create a local archive, and drag and drop emails into the local archive.
You can configure Outlook to automatically move your emails to the local
pst
file if you wish. See How to Automatically Move Mails From Outlook to PST.Note:
If you export your mail from
.ost
to.pst
you are creating a copy of your email not moving it.Further reading
