CAUSES:

  1. Network instability: Unstable network connectivity or delay issues can cause trouble in communication between the client and exchange server.
  2. Server overload: During peak hours or maintenance activities, there are high server loads, which reduces the server’s capacity to handle incoming requests, leading to connection failures.
  3. Configuration errors: Misconfigurations in the client application or Exchange server settings, for example-invalid credentials, invalid server address, etc., can cause connection failures.
Strategies to reduce data loss from this error:
  1. Network optimization: Ensure a stable and high-speed network connection by addressing network infrastructure issues, optimizing routing configurations, and prioritizing exchange server traffic.
  2. Server monitoring: Install and activate monitoring solutions to track server performance and allocate resource strategies to reduce overload.
  3. Configuration validation: Reviewing regularly and validating client applications and exchange server configuration for ensuring capability and accuracy.

Step 4: To resolve an issue with affected mailboxes, first check the mailbox database’s copy status. If there are issues, indicate the problem and check if the database is mounted.

If not mounted, try mounting it via the Exchange Management Shell (EMS) or Exchange Admin Center (EAC) if another user is working.

command to do it via PowerShell:-

[ Mount-Database MyDatabase ]

Note: it would be ideal if all steps go well, the database mounts, then the users can connect with the specific database. But in case the database fails to mount, there could be the possibility of a corrupt database, logs or PST files.
