Hi
We have now official lost a 60 user and 700 GB mail hosting customer to Exchange hosting !!
The issues we have experienced are many, but some of them are major for an enterprise customer. This customer in less than a month received and send more than 120,000 emails. Some users have more than 70,000 items in their inbox and receive +200 emails in a single day.
We migrated them from an Exchange 2010 solution which was getting old and expensive.
The initial migration seemed to work fine, but then all the complaints started to come in:
If the mailbox is above 5 GB, forget about EAS, it do not work and only create a lot of issues. And EAS is only supported by Outlook 2013 and higher.
So we thought the solution would be to use IMAP and then email and big mailboxes would be resolved. But this just add another problem instead! Now their calendar need to be moved to a Sharepoint list, so we did. But again we experience that users when they accept a meeting request it do go into their default calendar and not the Smartermail calendar, which breaks the sync to their mobile devices !!!
IMAP is also a lot slower to synchronize email, also a thing the customer picked up right away....
Then we were told to try the sourceforge caldav synchronizer, and this worked for about 10 people and then we are experiencing issues with other users. It syncs some of the items in the calendar but not all of them !!
We are so done with SM for any of the enterprise customers we have....
SM is not ready for any enterprise customer in our humble opinion...
Before we would consider going back to SM a few and for us very important things need to be fixed:
Support mailboxes as high as 50 GB (Exchange will go even higher), so lets not blindfold ourselves and think 5 GB will be enough! Enterprise want their email in their inbox not in archive folders and similar solutions.
Have calendar and contacts work flawlessly with the default calendar or the SmarterMail calendar. For some customers their calendar is their lifeline (this customer it was a deal breaker).
Some calendar entries especially recurring entries are moved back from 1 day to a month after the migration. So our customer experienced people not showing up to meetings, and they barely missed a meeting with clients from Singapore. Took some time to get the customer calmed down on that one...
Make the Global Address List available in Outlook.And the Mailing Lists need to be in there as well !!
I HOPE SM15 will address above issues, or SM will not be an alternative to Exchange. Would be nice to be able to compete with Exchange server.
frustrated regards,
