Please never downgrade to older versions

[jjzhuang]

Once you have upgraded to a newer version, installing an older version to downgrade may cause irreversible data corruption. We'll explicitly block this in a future release, but for now please avoid doing this.

If a new version you upgraded to has issues, let's try to resolve the issues. Going back in version usually cases more problems. If you must do that, you will probably have to delete all data on your computer and resync the account from remote server.

Hi jjzhuang,

In Zimbra Desktop:

I do not think you should block this in the future.

For instance:
In "1537 release", groups were available to send emails; in "1593 release" they are not.

I most of the time use groups to send emails so I cannot afford to keep "1593 release", in fact it is useless for me if I cannot use groups. So I have to go back to a previous release.

That's why you should not block it.

In fact, it should always be possible to go back....

Good day.
