We have been using Zimbra for a year now. Before that there were GAPPs. At first, everyone spat, saying that it was uncomfortable this way and that.
As a result, everyone likes everything, the mail never went to bed, everything works smoothly.
Subtle nuances:
1. The transition to Zimbra was painful. For there was no way other than how to download pop3 mail from Google and upload it to the user's mailbox. We (admins) got stuck..lis.
2. In the address book, we have a mess - it pulls absolutely everything that is in AD. But at the same time, everything is OK in contacts (contacts were pumped out of GAPPs). However, everyone forgot the concept of "address book" when they switched to Zimbru :) The search directory is configurable.
3. For some reason, the image in html is inserted 2 times. No solution has been found yet.
4. The company has such a thing as spam. Zimbra does a good job, but... There is a lot of spam. There is an spf entry. Zimbra filters about 95% of spam. Some end up in the spam folder. Sometimes they get into the inbox. Therefore, now we have to fine-tune SpamAssasin. Here's a tip: Zimbra's filtration rating is not defaulted to 6.6, you can safely do less, somewhere around 4 - 4.5
Actually, this is probably all that I remember now. Therefore important segments: migration. Consider this question. And spam. Spam must be fought.
