Recovery steps depend on where the contacts were stored and whether there is any backup. The context only covers Outlook/Microsoft accounts, so the following applies if those contacts were ever synced to Outlook or a Microsoft account on the PC.
- Check if contacts exist in Outlook / Microsoft account
- If Outlook was used on the computer or phone, sign in to Outlook (desktop app or Outlook on the web) with the same Microsoft account that was used before.
- In Outlook, go to People (Contacts) and check if the contacts are still there. If they are, no further recovery is needed.
- Check Deleted/Recoverable folders in Outlook (if contacts were in Outlook)
If contacts were deleted from Outlook, they may still be recoverable: New Outlook / Outlook on the web / Outlook.com- Open Outlook and go to People.
- Open the Deleted folder.
- If the contacts are there, right‑click each needed contact and select Restore.
- If not in Deleted:
- In People, open the Deleted folder.
- At the top, select Recover deleted (or Recover items deleted from this folder in New Outlook (Insiders)).
- Select the needed contacts and choose Restore.
- Restored contacts go back to their original folder or the default Contacts folder.
- In Outlook, open the Deleted Items folder and look for the missing contacts. If found, drag them back to Contacts.
- If not there and using an Exchange account:
- Go to Deleted Items.
- On the Home tab, select Recover Deleted Items From Server.
- In the window that opens, sort by Subject or From and look for the contact names (contacts show as envelope icons and often have blank “From”).
- Select the contacts and choose Restore Selected Items, then OK.
- Recovered contacts will appear in Deleted Items; move them back to Contacts.
- Check for Outlook data files (.pst) on the computer
If Outlook was used in the past on Windows, contacts may be in an Outlook Data File:- Open File Explorer.
- Browse to:
-
C:\Users\<YourUserName>\Documents\Outlook Files\ - or
C:\Users\<YourUserName>\AppData\Local\Microsoft\Outlook\
-
- Look for files ending in .pst. These can contain emails, contacts, and calendar.
- Copy any .pst file to an easy location (for example, Documents).
- In Outlook desktop: File > Open & Export > Open Outlook Data File, select the .pst, and open it.
- A new folder tree will appear; check its Contacts for the missing entries.
- If contacts are recovered, back them up
Once contacts are available again in Outlook, create a backup so they are not lost in the future:- In Outlook desktop:
- Select File > Open & Export > Import/Export.
- Choose Export to a file > Next.
- Select Outlook Data File (.pst) > Next.
- Select Contacts > Next.
- Choose a location and file name, then Finish.
- Store this .pst file on an external drive or cloud storage.
- In Outlook desktop:
If the contacts only ever existed in a Gmail account and were never synced to Outlook or backed up elsewhere, the recovery must be done through Google/Gmail’s own account and contacts recovery processes, which are outside the scope of the provided context.
