Guide

How to Block Emails in Outlook

Block senders and domains, the 10,000-entry limit, and what blocking cannot solve.

Create folders and subfolders, fill them with rules, and know when a category fits better.

Guide

Shared Mailboxes in Outlook

Setup, licensing, permissions — and the problem a shared mailbox does not fix.

The one nobody knows about

Outlook caps your rules at 256 KB — and says nothing when you hit it

Exchange limits the total size of all rules on a mailbox, not the number of them. A few long rules with many addresses can exhaust the quota, after which new rules silently fail to save and existing ones stop running. There is no warning.
