Outlook.com mailbox generating duplicate draft messages – suspected Exchange mailbox loop

Question

Hello Microsoft Support Team,

I am experiencing a serious issue with my Outlook.com mailbox that appears to be a server-side Exchange problem.

Symptoms:

• Emails are being duplicated and reappearing automatically.

Messages appear as drafts or system-generated messages.

Drafts folder is empty, no rules exist, no forwarding enabled.

This happens even when no devices are actively sending emails.

Removing mobile devices and desktop clients does not resolve the issue.

Emails sent from another account to this mailbox now fail with delivery errors.

Previously emails were delivered correctly; the issue started suddenly.

What I have already checked:

No inbox rules

No forwarding

No third-party apps connected

No mobile devices actively syncing

Outlook Web, Desktop, and Mobile all show the same behavior

Based on Microsoft Learn and community discussions, this behavior strongly matches an Exchange mailbox conversation loop / corrupted mailbox state, not a spam or client-side issue.

Request: I kindly request a server-side mailbox reset / Exchange mailbox state repair, including:

Conversation metadata reset

Draft state cleanup

Mailbox cache/index rebuild

This issue cannot be resolved from the client side and requires Exchange backend intervention.

Thank you for your assistance.

Hello serhat sütlü, 

Thank you for reaching out to the Microsoft Q&A. 

I understand how concerning it can be when your mailbox begins displaying unreadable folder names or repeatedly generates draft messages that cannot be deleted. I’ll guide you through the recommended steps to address this. 

Based on your description, this behavior is commonly associated with either: 

• A synchronization issue involving a connected email client (such as a mobile mail app), or 
• Unauthorized access to the account, where automated activity may be altering folders or generating drafts. 

To secure your account and stabilize the mailbox, please follow the steps below carefully: 

Step 1: Secure Your Account 

1. Sign in at: https://account.microsoft.com 
2. Go to Security > Advanced security options 
3. Select Change password and create a strong, unique password 
4. Choose the option to sign out of all sessions, if available 

Additionally, review your recent activity under Review activity to ensure there are no unfamiliar sign-in attempts.  If not already enabled, please turn on Two-step verification for added protection. 

Step 2: Check Mailbox Rules 

1. Sign in to https://outlook.live.com via a web browser 
2. Click the Settings icon 
3. Navigate to Mail > Rules 
4. Remove any rules you do not recognize 

Unexpected rules can cause automatic draft creation or folder movement. 

Step 3: Isolate Possible Sync Issues 

To rule out device synchronization conflicts: 

1. Temporarily disconnect mobile devices (Airplane mode) 
2. Using a web browser on a PC, delete the affected drafts and any corrupted folders 
3. Monitor the mailbox in Outlook on the web 

If the issue does not return while devices are disconnected, remove the account completely from the mobile device, restart it, and then re-add the account as a fresh setup. 

If the Issue Persists 

If the behavior continues after completing all the steps above, this may indicate a server-side mailbox issue that requires secure account verification.

5. Under Category, select Microsoft 365 & Office. 
6. Click Confirm. 
7. Select Chat with a support agent in your web browser. 

They will be able to securely verify your account and perform deeper diagnostics. 

Please let me know the outcome after trying these steps. I'm here to help.
