How can I minimize distractions and stay focused during meetings with my team when some members prefer to work remotely and others are in the office?

I totally understand your challenge! I've been in similar situations before, and it can be tough to keep everyone engaged when some team members are remote and others are in the office. One thing that's worked for me in the past is setting clear expectations and goals for each meeting. Make sure everyone knows what's expected of them and what they need to contribute. You can also try sending out a clear agenda beforehand so everyone knows what to expect.

Another thing that's helped me is using video conferencing tools that allow for more interactive participation. For example, Zoom has a feature that allows team members to share their screens and participate in live discussions. You can also use breakout rooms to facilitate smaller group discussions and encourage participation from everyone. Just make sure to communicate clearly about what you're doing and why, so everyone is on the same page.

As for implementing a mandatory in-office requirement, I wouldn't recommend it unless it's absolutely necessary. It can be a logistical nightmare, and it might not even solve the problem. Instead, I'd suggest focusing on building a strong team culture that encourages collaboration and communication, regardless of where team members are located. You can also try rotating team members' schedules so that some people are in the office one week and remote the next. This way, everyone gets a chance to experience both environments and can adapt to the team's needs.

Ultimately, it's all about finding a solution that works for your team. Experiment with different approaches, communicate clearly with your team, and be open to feedback and suggestions. I'm sure you'll find a way to get your meetings back on track!
