Zimbra Forums

Hello,
Few day ago I upgraded the version from 8.7 to 8.8.15_GA_3869.FOSS and now I have a problem with viewmail - it doesn't work, I can't see emails. I tried undeploy and redeploy. Zimlet viewmail is enabled in version 8.5.0 On the previous version zimbra worked fine, now not. What can I do?

Hey there just follow below steps to solve your problem

$ cd zimlets
$ ls
you will get a list of zimlets over there and then you install manually by below command

$ zmzimletctl deploy com_zimbra_viewmail.zip

Enjoy !!

I have tried this step but its still not working for me
My new version is 8.8.8_GA_2009.FOSS
