Hi, Sydney
Welcome to Microsoft Q&A forum.
Sorry for this unwanted experience regarding you receiving email notifications for your own comments. Here are some workarounds you can try to resolve this issue:
Turn off Microsoft 365 comment notifications at the account level
- Web > office.com > Sign in > top right gear > Settings > Notifications > turn off items related to comments, replies, and file activity
- This central switch controls cross‑app email notifications for SharePoint, OneDrive, and Office on the web. If your tenant recently moved toggles out of OneDrive settings, they show here. This approach is consistent with Microsoft guidance that end users manage their own notification preferences, since tenant‑wide overrides are not exposed.
Unfollow the specific Word comment thread
In Word on the web or desktop with the modern comments pane open > for a comment that is generating mail > select the Bell or Following control > Unfollow.
Unfollowing stops thread‑level mails, including those triggered by your own replies.
Check for SharePoint “Alert me” subscriptions on the library or file
Sometimes “alert” rules exist on a library or item and will mail on updates, including comments.
- SharePoint library > … > Alert me > Manage my alerts > remove any alerts for that library or file.
Review OneDrive/SharePoint comment and @mention behaviors
@mentions always generate notifications to the mentioned user. Make sure you are not @mentioning yourself inadvertently and consider avoiding @mentions when you do not need a mail copy. DLP or compliance policies can also send informational emails when content changes, which looks like a “policy tip” or “notification.” If your org uses DLP, your admin can tune those end‑user notifications.
Hope this helps. Feel free to get back if you need further assistance.
