How many days in outlook 2010 mail deleted items

In Outlook 2010, the default retention period for the "Deleted Items" folder is 14 days. This means that emails deleted from the "Deleted Items" folder will be permanently deleted after 14 days.

However, you can change this retention period to a custom value. Here's how:

1. Open Outlook 2010 and go to the "File" menu.
2. Click on "Options" and then click on "Mail".
3. Scroll down to the "Deleted Items" section.
4. Click on the "Settings" button next to "Empty Deleted Items folder without prompt".
5. In the "Retention" section, you can select a custom retention period from the dropdown menu. You can choose from 1 day to 30 days, or select "Never" to keep deleted items forever.

Note that if you change the retention period, it will apply to all deleted items in the "Deleted Items" folder, including those that were deleted before you changed the setting.

It's also worth noting that if you have Outlook configured to use a server-side delete (e.g., Exchange Server), the deleted items may be retained on the server for a longer period of time, even if you've set the retention period to a shorter value in Outlook.
