email box almost full

One of the very common communication is via emails, they do fill up our Inboxes and some of us don’t have time to clean up, which you can do it automatically or manually.  Just carefully when setting automatically to delete, because we as human beings forget and take automation as a privilege, and sometimes it deletes some things we want to keep as history. Here is how to clean up your old email manually or automatically.

Option 1: Manually

Option 2: Automatically via a set of rule

Option 1: Manually

First, Sign-in to your Office 365 by going to https://outlook.office.com
Once you have signed in go to Gear Icon at the top left then go all the way to the bottom, select View all Outlook settings

View all Outlook settings

You will see another pop-up window

Go to Settings>General>Storage>Then select the folder you want to clean up old emails

Then on the right side, you will have an option to choose from, All, 3 months and older, or 6months and older, or 12 months and older

As, soon as you select the option, it will start deleting your old emails

Note: Items will be permanently deleted

Automatically via a set of rule

Once you have signed in go to Gear Icon at the top left then go all the way to the bottom, select View all Outlook settings

You will see another pop-up window

Go to Settings>Mail>Rules>Then click Add New Rule

Settings>Mail>Rules

Now add a condition

There are so many options, select whatever you like, I am selecting “Before 4/8/2022

Note: you will need to just update the date in the rule later on.

Then select the Action, you want to do, I am selecting “Delete

You can get your emails back from Deleted Items unless the default email deleted policy will clean up have permanently deleted, which most cases 30, 60, or 90 days from the date it was deleted

Also, added an exception so I can keep Importance with “High” or whatever you like.

Once you are happy with everything click Save

That’s it, don’t forget, if you set to delete or whatever condition you have selected, it will automatically do just that, in case later in time you might be wondering what’s happening to my old emails

To change the Date or Turn off the rule, just go to Mail>Rules and click on the pencil icon to change or the Toggle button to turn off.

Double-check all selections before running, because there are no ways to stop, once it started the action you have selected in the rule. If you are unsurely tested on some test account(s).
