Lync 2010 client version summary

I’ve long stopped blogging Lync 2010 client versions, but I recently had cause to go for a bit of a search, and there were some I encountered in the wild that I’d not previously documented here.

Here are a few more versions and some links. This isn’t a comprehensive list, but is intended to augment those that will be revealed if you use the Search function on the blog.

Some of the below was sourced from Andrew’s blog, and others from Frank Carius.

As best I can tell, 4.0.7577.4540 from Sept 2017 remains the last update to this long-obsolete client.
