Quarantine email alerts to users to allow the email to their inbox (tricky but handy) - tricky if one doesn't have third-party email security, handy if one has got good third party email security).

Teams has been really valuable recently as a feature of Office 365 when I've been working on projects where I've needed to collaborate with quite a large group of people.

The products are quite simple for the end-users to use, the up-time is very good, the product is practically maintenance-free, and the multi-layer security is excellent from the security standpoint.

Office 365 has positively impacted my organization by making the salespeople more accurate because they've been able to use the features in Excel instead of relying on the calculator or adding machine, and some of the AI with writing and things with Word has helped improve things with that, too.

It seems like every other week when we log into the administrative portals, it doesn't matter which one, it could be the active directory portal, it could be the exchange admin center or SharePoint admin center, it seems like Microsoft is consistently updating with new versions of the admin centers, which can be frustrating.

It would be a fantastic opportunity if their solution could be used in combination with VoIP software, allowing you to combine VoIP software and Office 365 on a single platform.

The one big problem with the solution is if you are presenting in Teams and someone puts their hand up, you don't get a notification. If you are running a meeting and just presenting you don't know that people have their hands up and want to ask a question.

I haven't used Copilot too much because I don't have a license for that at the moment.

The online applications have limited functionality compared to the local applications.

Normally, they have a way to work with specific developments, and I think they shouldn't allow the partners to make some changes they have made. When I have a client with a lot of changes, we have a problem with that because there aren't rules to develop inside the ERP, so you can do anything.

If two people update the same file, it causes issues.

One of the big changes is when Microsoft updates anything, they will switch where some of the settings are and where to find them, which becomes a little frustrating because you're used to it in one spot and it's someplace else.
