Support FAQ

If your MailStore Server license includes our Premium Support or if you are using the MailStore Service Provider Edition, our support team is also available by phone.

What does the Update & Support Service include?

A valid Update & Support Service includes the following services:

Technical support from MailStore by OpenText or your responsible partner
Updates to the latest MailStore Server version
The basis for adding additional users to your existing installation

A new MailStore Server installation already includes an Update & Support Service for up to three years.

What conditions apply to extending or cancelling the Update & Support Service?

The contract must be extended before the end of the contract period. Customers will be notified ahead of time and automatically will receive an offer. Cancellation or renewal is not required. Please note, however, that without valid Update & Support Service you cannot receive any of the services listed above.

If your Update & Support Service has already expired and you would like to reactivate it, you need to purchase an upgrade. (See the question ’Can you reactivate an expired Update & Support Service?’)

For an upgrade quote, please contact our customer service at [email protected] or +1 (800) 747 - 2915.

Can you reactivate an expired Update & Support Service?

Yes, it is possible to reactivate an expired Update & Support Service by purchasing an upgrade. An upgrade costs 70 percent of the list price of the existing user licenses, and is thereby significantly more expensive than a renewal. The contract period of the new Update & Support Service begins on the date of purchase.

For an upgrade quote, please contact our customer service at [email protected] or +1 (800) 747 - 2915.

What are the differences between Standard and Premium Update & Support Service?

Services within the contract period	Standard (included in the price)	Premium (optional)
Free bug fixes, patches and interim releases	Yes	Yes
Free upgrade to new main versions	Yes	Yes
Access to unreleased hotfix versions	No	Yes
