What Causes Exchange Server to Recreate Meetings?

Before jumping into the fixes, it’s essential to understand why this issue occurs. Common reasons include:

1. Delegate Permissions Issues

If someone else manages your calendar as a delegate, changes made on their side might result in recreated meetings.

2. Mailbox Corruption

A corrupted mailbox can lead to unexpected behaviors like duplicate meetings or recreated entries.

3. AutoDiscover Misconfiguration

AutoDiscover ensures seamless synchronization of your calendar and other data. Misconfigurations here can trigger meeting recreation.

4. Outdated or Buggy Exchange Server Versions

Older versions of the Exchange Server might have bugs that interfere with calendar operations.

5. Third-Party Applications

Third-party calendar syncing tools can conflict with Exchange Server, causing meeting recreations.

How to Stop Exchange Server from Recreating Meetings

Here are practical solutions to help you resolve the issue:

1. Check and Update Delegate Permissions

• Go to File > Account Settings > Delegate Access in Outlook.
• Review and adjust permissions for all listed delegates.
• Ensure that unnecessary delegates are removed to prevent unintentional changes to your calendar.

2. Repair Your Mailbox

Corrupted mailboxes can lead to meeting recreation issues. To fix this:

• Alternatively, run the New-MailboxRepairRequest PowerShell command:powershellCopy codeNew-MailboxRepairRequest -Mailbox "user@domain.com" -CorruptionType CalendarFolder

3. Verify AutoDiscover Settings

A misconfigured AutoDiscover can cause calendar sync problems. To check:

• Use the Test E-mail AutoConfiguration feature in Outlook.
• Ensure your AutoDiscover service points to the correct Exchange Server.

4. Update Exchange Server

If you’re running an older version of Exchange, updating to the latest cumulative update (CU) might fix calendar-related bugs.

• Download updates from Microsoft’s official site.
• Apply updates during off-hours to minimize disruptions.

5. Disable Problematic Third-Party Tools

Third-party tools like calendar syncing apps or add-ins might interfere with your Exchange Server.

• Temporarily disable all third-party tools.
• Re-enable them one by one to identify the culprit.

6. Clear the Calendar Cache

Clearing the calendar cache can resolve issues caused by outdated or conflicting data. Here’s how:

• Open Outlook.
• Navigate to File > Account Settings > Account Settings.
• Select your account and click Change > More Settings > Advanced.
• Disable Cached Exchange Mode temporarily, then re-enable it.

7. Recreate the User Profile

Sometimes, recreating the affected user profile can resolve the issue:

• Open Control Panel > Mail.
• Click on Show Profiles, then select Remove for the problematic profile.
• Add a new profile and configure it with your Exchange account.

8. Inspect Calendar Logs

Exchange Server keeps detailed logs of calendar activities. These logs can help identify the root cause of the issue:

• Use the Search-MailboxAuditLog PowerShell command to retrieve logs.
• Look for unusual activities or recurring events related to recreated meetings.
