Hi @Hugo-Stiglitz

Yes, on servers with heavy traffic, Exchange Server can generate hundreds of transaction logs per day. You must select a location for these logs carefully. The disk you allocate to hold these files must contain enough space to store the transaction logs until Exchange Server removes them. Exchange Server deletes transaction logs whenever it completes a full backup.

Use Windows Server Backup to back up Exchange

For enabling circular logging, when the circular logging is enabled, the transaction log is cleared right after the transactions have been moved to the database. Once the circular logging is enabled, then the additional log files are not created.

It will keep growing till it runs out of space.

Get an Exchange Aware FULL backup ASAP to clear those logs or enable circular logging.

Do this soon - before you run out of space and the server crashes.

Do not remove the logs manually.
