In classic Outlook 2016, first open Deleted Items. If the message or other item is still there, select it and use Move to return it to Inbox or another folder. If it has been removed from Deleted Items, make sure Outlook is online, select Deleted Items > Home > Recover Deleted Items From Server, choose the item, and select Restore Selected Items. Outlook restores it to Deleted Items first; move it from there to its final folder.
This recovery command works only with accounts that support server-side recovery, generally Exchange-based mailboxes. If the command is missing, the account may not support it. IMAP and POP accounts cannot recover a contact after permanent deletion or after it has been removed from Deleted Items. Retention is controlled by mailbox policy, so an item that has passed the policy period may be permanently unavailable.

Where a deleted Outlook 2016 item can still exist
Deleting an email, calendar appointment, contact, or task does not always remove it immediately. Outlook normally places it in Deleted Items. Emptying that folder or deleting an item from it can move the item into the mailbox’s hidden Recoverable Items area, but only when the account and its retention policy support that process.
| What you see | Where the item is likely to be | What to do |
|---|---|---|
| The item is visible in Deleted Items | Deleted Items folder | Select it, choose Move, and pick Inbox or another destination. |
| The item is gone from Deleted Items and the recovery command is available | Recoverable Items on the server | Use Recover Deleted Items From Server, then Restore Selected Items. |
| The command is absent | Account may not support server recovery, or Outlook may not be connected correctly | Check the account type and connection; contact the mailbox administrator if it is an organization account. |
| The retention period has expired or an administrator purged the item | No recoverable copy may remain | Ask the administrator whether a policy-based or backup recovery is possible. Recovery is not guaranteed after purge. |
Microsoft describes recovery as often possible when an item is in Deleted Items or Junk Email. “Often” matters: account type, mailbox policy, permissions, connectivity, and data-file condition determine whether Outlook can return a particular item.

Before you start: check the account and retention conditions
Use classic Outlook 2016
These labels apply to the desktop, classic Outlook 2016 interface. Open Outlook and wait for it to finish connecting before attempting server recovery. A disconnected or offline session can hide the command or prevent the result list from loading.
Identify the account type
Server recovery is an Exchange mailbox feature. A work or school mailbox may be hosted on Exchange, while a personal account configured as IMAP or POP uses different storage and deletion behavior. In Outlook 2016, open File > Account Settings > Account Settings and review the account’s type on the Email tab. If the account is IMAP or POP, do not expect the server-recovery command to restore a contact after permanent deletion or removal from Deleted Items.
Understand the mailbox policy
Exchange keeps permanently deleted items in Recoverable Items only for the period set by the mailbox administrator. Microsoft gives 30 days as an example of a Deleted Items retention policy and notes that another policy can allow up to 14 additional days in Recoverable Items. Those figures are examples, not universal Outlook 2016 defaults. Your organization can use a shorter, longer, or otherwise different policy, and administrators can purge items before the nominal period ends.
Recover an item that is still in Deleted Items
- In the folder pane, select Deleted Items under the affected mailbox.
- Locate the message, appointment, contact, task, or other item. Sort or search within the folder if necessary, but confirm the sender, subject, date, or item name before moving it.
- Select the item. To select several items, use the normal Windows multi-selection methods.
- On the ribbon, choose Move, then select Inbox or the folder where the item belongs. You can also choose another appropriate folder in the same mailbox.
- Open the destination folder and verify that the item is present. For a calendar item, contact, or task, check the corresponding Outlook module rather than assuming that it appears as an email.
Moving an item is preferable to dragging it blindly because the Move menu makes the destination explicit. If the item was accidentally moved to a different folder rather than deleted, use Outlook search across the mailbox before attempting server recovery.

Recover an item after it was removed from Deleted Items
Open the server-recovery list
- Confirm that Outlook is connected to the mailbox.
- Select Deleted Items.
- On the Home tab, select Recover Deleted Items From Server.
- Wait for the list to load. The list represents items still retained by the server, not every item ever deleted.
Restore the selected item
- Select the required item in the recovery window. Check identifying details carefully, especially when several messages have similar subjects.
- Select Restore Selected Items.
- Return to Deleted Items. Microsoft says restored items are placed there first.
- Select the restored item and use Move to send it to Inbox, Calendar, Contacts, Tasks, or another suitable folder.
- Open the destination and verify the content, attachments, date, and participants. A successful restore places the item back in the mailbox; it does not automatically put every item in its original folder.
If you need to recover several items, restore only the ones you can identify confidently. Restoring unrelated items makes later sorting harder and does not extend the retention period.
What to do when “Recover Deleted Items From Server” is missing
The missing command is usually an account-support or connection issue, not a hidden Outlook setting. Microsoft notes that an account may not support recovery when the command is absent. Work through these checks in order.
1. Confirm the folder and ribbon
The command appears when Deleted Items is selected. Click that folder in the mailbox whose item you are trying to recover, then open the Home tab. Selecting a local folder, an archive, or another mailbox can show a different ribbon and no server-recovery command.

Reconnect the computer to the network, allow Outlook to synchronize, and check whether new mail can be sent or received. An offline session cannot reliably query Recoverable Items. After connectivity returns, select Deleted Items again and look for the command.

3. Check whether the account is Exchange-based
Use File > Account Settings > Account Settings and inspect the account type. Exchange-supported mailboxes can expose server recovery. IMAP and POP accounts have different server behavior; Microsoft specifically states that they cannot recover a contact after permanent deletion or removal from Deleted Items. If the account is unsupported, Outlook 2016 cannot manufacture a Recoverable Items list locally.
4. Ask the mailbox administrator
For a work or school mailbox, an administrator controls retention, permissions, and whether the mailbox is eligible for recovery. Ask the administrator to verify the retention policy, confirm that the item has not been purged, and check whether your account has the necessary permissions. Provide the item type, approximate deletion time, original folder, and mailbox address so the administrator can search accurately.
Can an item be recovered after Deleted Items was emptied?
Sometimes. On a supported Exchange mailbox, emptying Deleted Items can leave the item in Recoverable Items until the administrator’s retention or purge rules remove it. Use the server-recovery procedure immediately; waiting can allow the policy window to expire.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThere is no universal Outlook 2016 recovery deadline. The frequently cited 30-day period is Microsoft’s example of a policy, not a built-in guarantee. Microsoft also describes a possible additional period of up to 14 days under another policy. Your administrator may configure different values, and a deliberate purge can make an item unavailable sooner.

If the item does not appear in the recovery list, ask the administrator whether retention has expired, a purge occurred, or an organizational backup exists. Outlook’s client interface cannot recover an item that the server has permanently discarded.
Troubleshoot the error “Outlook was unable to recover some or all of the items in this folder”
Microsoft’s Outlook 2016 known-issue guidance says this cloud error was fixed on the server side and advises restarting Outlook after the fix. Restarting is therefore the first response, but continue with the checks below if the error returns.
- Close Outlook completely. Wait briefly, then open it again and allow the mailbox to reconnect.
- Select Deleted Items and repeat Home > Recover Deleted Items From Server.
- If only some items restore, retry with a smaller selection. Record which item fails and its approximate deletion date.
- Verify that the account is Exchange-supported and that you have permission to recover items.
- Check connectivity by confirming that ordinary send and receive operations work.
- Ask the administrator to confirm the retention policy and whether the item was purged or is still in Recoverable Items.
A server-side fix cannot restore an item that has already aged out of retention. It also cannot overcome an unsupported IMAP or POP account. Treat the error as a diagnostic signal and supply the administrator with the exact wording, mailbox, item type, and time of the attempted recovery.

When a damaged PST or OST is involved
Outlook data-file corruption can make an item appear missing or prevent a folder from opening correctly. Microsoft’s PST/OST repair guidance warns that some items may remain unrecoverable when they were permanently deleted or damaged beyond repair.

Data-file repair is relevant mainly when the problem is local corruption—for example, Outlook cannot read a folder that should exist. It does not recreate a server item after retention has expired, change an account that does not support server recovery, or bypass mailbox permissions. Before attempting any repair, preserve a copy of the affected data file and follow Microsoft’s instructions for the specific file type. If the mailbox is Exchange-based, the server’s retention state remains authoritative.
Recovering different Outlook item types
Email messages
Move a message found in Deleted Items to Inbox or another mail folder. For a message returned by server recovery, restore it first, then move it from Deleted Items. Check attachments after the move.
Calendar appointments
After restoration, open the Calendar module and verify the appointment’s date, recurrence, attendees, and reminders. A restored calendar item may not be visible in the mail view even though it was recovered successfully.

Contacts
Contacts are subject to the account limitations described above. Microsoft specifically notes that IMAP and POP accounts cannot recover a contact after permanent deletion or removal from Deleted Items. On a supported Exchange mailbox, use the same Deleted Items and server-recovery sequence, then move the restored contact to the appropriate Contacts folder.
Tasks and other Outlook items
For tasks and similar items, verify the item in the Tasks module after moving it. If a deleted folder itself is involved, ask the administrator about mailbox recovery options; folder behavior and permissions can differ from recovery of an individual item.
When to stop trying in Outlook 2016
Stop repeating client-side recovery attempts when the item is absent from Deleted Items and the server list, the retention period has expired, or the administrator confirms a purge. At that point, only an administrator-managed backup or retention system might help, and availability depends on the organization’s configuration. A PST/OST repair cannot override those limits.
Keep a concise record for support: account type, mailbox, item type, original folder, approximate deletion time, whether Deleted Items was emptied, the exact error text, and the steps already attempted. Those details let an administrator distinguish a policy expiration from a permissions or connectivity problem.

How to reduce the chance of permanent loss
- When you notice a deletion, recover it immediately rather than waiting for the retention window to approach.
- Move recovered items into a clearly named folder and verify them before deleting anything else.
- For organizational mailboxes, ask the administrator what retention period applies to Deleted Items and Recoverable Items; do not assume the example 30-day period applies to your account.
- Keep Outlook connected while performing recovery so the client can query the server.
- Use an administrator-managed backup or retention plan for records that must survive mailbox purges.
