Apache reverse proxy for Amazon WorkMail service?

Question

Apache HTTP Server

Guys, help me
out mail, which is Amazon WorkMail, dir. already took the acc and everything works. The requirement is that it looks for employees externally as on our domain (eg corp.company-name.tld/mailbox), the tambourine brought me to Method not allowed, and judging by the debugging results, it is AWS that tells me this. Removed X_FORWARDED_FOR and all that is needed from the headers (ProxyAddHeaders off directive) that Apache sends towards AWS so that AWS does not think that I am deceiving users by changing the domain.
Those. it’s impossible to notice a catch on the part of AWS (in theory, and if I did everything right, but I still don’t know what else to foresee), but for some reason the mail panel does not work and gives out 405 Method not allowed. Those. support is paid by Amazon and pay for them to say that this is impossible (as well as spend at least a few days, if not a week) on explaining those. details to the Indians - also there is no desire.
Whether there is an opportunity in general to understand where to dig at least?
Thank you so much!
