How to identify the name and location of your personal folders file

Microsoft Outlook for Windows

1. Start Outlook.
2. Click the File tab in the Ribbon, and then click the Info tab on the menu.
3. Click the Account Settings tab.
4. Click Account Settings again.
5. Click Data Files.

   Checking the default locations in addition to verifying the existing location is always recommended as there might be some disconnected pst-files which you might have forgotten about but still like to keep anyway. The default locations to check are:

   • C:Users%username%AppDataLocalMicrosoftOutlook
   • C:Users%username%DocumentsOutlook Files

   You may have more than one .pst file you are using. Note the path and file name of each of these files. The name of any .pst file (other than the default - Outlook.pst) will be the same name within your folder structure.

6. Click Close, click OK, and then click Exit and Log Off on the File menu to quit Outlook.

How to backup/copy your personal folders file (.pst)

Caution - the Office 365 support team does not recommend storing data locally for the following reasons:

• Security - if someone gets access to your computer, they can easily extract the data from the local data file.
• Loss of data - if the data is not backed up, it cannot be recovered.
• Deleted data - if deleted, Microsoft's recovery tool cannot be used to restore the data.

If you found a local pst file, use the instructions below to backup/copy. If you do not have one and want to create one, follow these instructions: create an Outlook data file. After you have created a local pst folder, you will need to manually move/copy items into it. If you use the move command, it will remove the item from within your Office 365 account and place it within your local folder. This means it will no longer be visible in Outlook on the web and can only be accessed from the computer where you have this local file configured.

1. On the Start menu, point to Programs, and then click Windows Explorer.
2. Browse through the files to the location of your .pst file (from above).
3. Copy your .pst file to the location that you want.

How to point Outlook to your new personal folders file

Important: If you have reconfigured Outlook with a new proflle, use the steps below to connect your pst file to this profile.

Microsoft Outlook for Windows

1. Click the File tab.
2. Click Open and Export
3. Click Open Outlook Data File.
4. Search and find the .pst file you want to connect, and then click OK.
5. On the File menu, click Exit.
6. Restart Outlook.

As of October 13, 2020, only these versions of Office are supported for connecting to Office 365 (and Microsoft 365) services:

• Microsoft 365 Apps for enterprise (previously named Office 365 ProPlus)
• Microsoft 365 Apps for business (previously named Office 365 Business)
• Office 2019, such as Office Professional Plus 2019
• Office 2016, such as Office Standard 2016

Examples of Office 365 services include Exchange Online, SharePoint Online, and OneDrive for Business.

For Microsoft 365 Apps, you must be using a supported version. For a list of which versions are currently supported, see Update history for Microsoft 365 Apps.

Important

We won’t take any active measures to block other versions of the Office client, such as Office 2013, from connecting to Office 365 services, but these older clients may encounter performance or reliability issues over time.

Impact of using older Office clients to connect to Office 365 services

After October 13, 2020, ongoing investments to our cloud services will not take into account older Office clients. Over time, these Office clients may encounter performance or reliability issues. Organizations that use these older clients will almost certainly face an increased security risk and may find themselves out of compliance depending upon specific regional or industry requirements.

Therefore, administrators should update older Office clients to versions of Office supported for connecting to Office 365 services.

Upgrade resources available to administrators

We recommend that you upgrade older Office clients to a subscription version of the Office client, such as Microsoft 365 Apps for enterprise. The most up-to-date subscription versions of the Office client are always supported connecting to Office 365 services.

We provide various services to help you upgrade to subscription versions of the Office client. The following list provides some examples of resources that are available:

• Microsoft FastTrack, for migration and deployment assistance from Microsoft experts.
• App Assure, for assistance from Microsoft with application compatibility issues.
• Deployment guide for Microsoft 365 Apps, for technical documentation.
• Product lifecycle dashboard and upgrade readiness dashboard, for users of Microsoft Endpoint Configuration Manager (current branch).
• Readiness Toolkit for Office add-ins and VBA, to help identify potential issues with add-ins and VBA macros used in your organization.
