Why am I unable to forward an E-mail in Windows 10 ?

[Windows Central Question]

Until yesterday, it was all fine. Today, I tried to forward an E-mail sent by my sir to my friend, which had an attachment. I got Lumia 730 and I recently upgraded it to Windows 10. When I tried forwarding, I myself had to write the email address of my friend. Moreover, if I made a single mistake, it wouldnt let me erase. I had to now, delete the mail. And again do the process. Once i was done with writing the email-address. It wouldn't let me send the mail. Like it wont let me touch it. Urgh! Why so many problem?

i was having the same problem which i solved it by adding the same account (in my case gmail) again as a second account, you will get a pop up and will ask you to give permissions. just need to switch to the "new account" and sync.Hope it work , know not a permanent solution . But t you can try

Did you manage to solve the issue?
It is the same with my phone (Lumia 640), I cannot even answer an e-mail because the send button is just greyed out.
It would be great to solve the issue.
Yesterday it worked fine.
