Is HTTP/2 supported with Mac Mail? We are having issues with Mac Mail connecting to Microsoft Exchange environments running on Server 2016. HTTP/2 is used with IIS 10 (on Server 2016) and we are seeing posts that reverting Windows back to HTTP/1.1 will let Mac Mail connect.
Yeah all of that I have already verified. I'm finding other people post about Server 2016 using HTTP/2 with Mac Mail and it not working. I would like to know if there is a workaround on the Mac or at least information showing this is a known issue with Mac Mail.
I tested and disabling HTTP/2 on Server 2016 let Mac Mail connect. So that tells me that Mac Mail DOES NOT support HTTP/2 at this time.
I have disabled http/2 on server 2016, worked for me. Excellent. Thanks for posting the article
