Configure Outlook rules for project emails

Step 1: Connect Outlook to Microsoft 365

Open the desktop version of Outlook from Microsoft 365 Business Basic. The plan costs 6.00 € net per user per month (as of August 2026, microsoft.com). Sign in with your company account. Skip this step and rules cannot be managed centrally later.

Step 2: Create folder structure

Create three new folders in the mailbox: “Project A – Incoming”, “Project B – Incoming” and “Archive – Completed”. Name the folders exactly like this. Without this structure rules have nowhere to move messages.

Step 3: Define first rule for Project A

Go to File > Manage Rules & Alerts. Click “New Rule”. Choose “Apply rule on messages I receive”. Set the condition to “with specific words in the subject” and enter “[Project A]”. As action select “move to folder” and pick the folder “Project A – Incoming”. Save the rule. Without this step all messages stay in the inbox.

Step 4: Add second rule for Project B

Repeat the process from step 3, but replace “[Project A]” with “[Project B]” and choose the matching folder. Test the rule right away with a test mail. Without testing a wrong condition can later misfile hundreds of messages.

Step 5: Add exception for internal emails

Edit both rules and add the exception “sender is in the address list ‘Company internal’”. Internal messages stay in the inbox this way. Missing the exception sends important internal coordination into project folders.

Step 6: Activate rules on the server

Enable the option “run rules on the server” in the rule settings. This works only with Exchange or Microsoft 365 accounts. With POP3 or IMAP accounts rules run only locally on the device. This step is often skipped, forcing separate configuration on every device.

Step 7: Check mobile sync

Open the Outlook app on the phone. Tap the gear icon and confirm “sync folders” is enabled. Server-side rules appear automatically here. If this step is forgotten the new folders are missing on the phone and messages keep landing in the general inbox.

Step 8: Review rules after two weeks

After fourteen days count how many messages landed in the project folders. Open the folder “Project A – Incoming” and sort by date. If messages appear misfiled, adjust the subject condition. This review step often fails because users forget the rule after initial setup and never schedule time for corrections.
