To restore lost data in Exchange, select the Exchange tab.

Exchange data restore tab


If there are many mailboxes in the subscription, use the search field to find the mailbox you want to search. Then, click the user whose data needs to be restored.

This will open the mailbox in folder view. To find the data you are looking for, you can either:

  • Search by entering text into the search field, or
  • Browse through the folders to find what you want to restore.


Search to find

Enter keywords from the header of the email or the name of the folder you are looking for. Backup For Microsoft 365 searches the subject line of emails, file and folder names, contact names, and more. However, to ensure privacy, it does not search the body of emails or files.

Note: currently, the Backup For Microsoft 365 UI has a search result limit of 500 items. Workarounds for this include the use of browsing to narrow the search within a specific folder or Smart Search.

To narrow your search, you can use the following Smart Search tags:

  • To:[Recipient Name] E.g. To:Bob
  • From:[Sender Name] E.g. From:Jane
  • Subject:[Subject Keyword] E.g. Subject:Sales

Search to find

Backup For Microsoft 365 also supports a variety of Advanced Search capabilities, including Elasticsearch, Wildcards, and RegEx.

Note: for a RegEx search, enter "RegEx:" before the query.

If multiple items appear in a search, you can sort the items by Attachment, Sent by, Subject, or Date.

Browse to find

Click any folder or sub-folder to browse its contents, and use sorting and filtering to focus your search.

  • Sort: To sort, click the column heading (Attachment, Sent by, Subject, and Date)
  • Filter: To filter by Date, click the filter icon and select an option

As you drill into folders, your path is tracked at the top of the screen. If you want to navigate back, simply click on the path to open a menu, and select the folder you want to return to.

Individual Item Restore

To restore individual folders or items, select them and click Restore

Note: when needing to restore more than 200 individual items, it is best practice to perform a bulk restore (e.g. full mailbox, folder, list, etc.) or perform multiple batches of under 200 individual restores. Currently, extremely large batches of individual restores (e.g. over 200) may not complete.

Individual Item Restore

Bulk Restore

Backup For Microsoft 365 also supports bulk restore of Full Mailboxes and Calendar, as well as all Contacts, Tasks, Notes, or Journals. On the homepage of the Exchange tab, click the ellipsis (...) to the right of any mailbox, and select what you want to restore.

Bulk Restore

Currently, for Shared Mailbox, the only full restore that appears on the homepage of the Exchange tab is Restore Full Mailbox. However, within any mailbox type, you can perform a full restore of Contacts, Calendar, Tasks, Notes, and Journals, by selecting the folder in the folder-view.

Important: when a full restore is done with Backup For Microsoft 365, it is merged with existing content. In other words, the data is de-duplicated before it is inserted into the mailbox. Backup For Microsoft 365 does not overwrite or delete data at any time.

Restore Individual Contacts

You can restore contacts individually or in bulk from the folder view of the mailbox.

  1. Click the Contacts folder
  2. Select the contacts you want to restore
  3. Click Restore

Restore Individual Contacts

Restore Process

While the restore is initiated with a single click and Backup For Microsoft 365 makes every effort to restore the content as quickly as possible, the time required to complete the restoration is based on a variety of external factors, including:

  • The overall size of the data set being restored.
  • Microsoft Office 365 throttling.
  • Microsoft Azure throttling.
  • The overall availability of Office 365.

During this time, you can view the status of the restore by hovering over the progress indicator next to the mailbox being restored.
