Distribution box number restriction
Microsoft Exchange Online will limit each organization to 3,000 dynamic distribution groups (DDGs) starting November 2025. Find the Exchange Online limits for various service areas, including address book limits, mailbox storage limits, and reporting and message trace limits, to name just a few. Few tenants might be affected, but the question might be asked why Microsoft is limiting DDGs at this point. This change is automatic and cannot be turned off. Adjust limits for individual mailboxes or all new mailboxes via mailbox plans. -
Secondary Electrical Principles of Relay Protection
The article provides an overview of protective relaying principles and their applications for high-voltage power system components. It covers the protection methods for generators, transformers, buses, and transmission lines using various relay types to detect and isolate faults.

Fiber Fiber Disk Tilted 8 Degrees
A fiber disk laser is a with transverse delivery of the light. They are characterized by the pump beam not being parallel to the active core of the (as in a ), but directed to the coil of the fiber at an angle (usually, between 10 and 40 degrees). This allows use of the specific shape of the pump beam emitted by the, providing the efficient use of the pump. -

Does the galvanized sheet metal for cable trays rust
Yes, galvanized steel can rust, but it takes a long time. The zinc coating protects the steel for decades, often lasting 50 years or more in mild environments. In harsher conditions, like coastal or industrial areas, rust might appear sooner, but this protection may still last. For procurement specialists and facility managers, specifying galvanized steel cable tray for indoor electrical installations is a standard practice. This white paper compares the High Resistance (HR) and Hot-Dip Galvanising (HDG) solutions and highlights the new High Resistance range, ZnAl. The galvanization process is the primary anti-corrosion treatment for cable trays. The following provides a comprehensive explanation, covering standards, ranges, testing, and special application. Stainless Steel: Highly resistant to corrosion, ideal for harsh environments. Aluminum: Lightweight and naturally corrosion-resistant. Fiberglass: Non-metallic option, immune to rust. Customized. The only safe option that can be used in an open environment or a place with a high level of moisture is the hot-dip galvanized (HDG) steel. The wrong one is the most common error, which results in rust showing itself much earlier than expected.
