Why is MailStore Server a good fit to run alongside Office 365 / Microsoft 365?
Microsoft Office 365 is on the rise, and the number of business users is increasing every day. At MailStore, we have noticed that an ever-increasing number of customers are switching to the cloud-based application of the tech giant from Redmond, USA. This trend is also supported by the information that support for Exchange Server 2010, Windows Server 2008, and Windows Small Business Server 2011 will end in 2020. However, customers who use MailStore along with other on-premises email servers are also wondering whether our MailStore Server solution can be used with Office 365. The simple answer is a resounding "yes, it can!" You can run MailStore Server with Office 365 and continue to take advantage of all the advantages our software provides in terms of email archiving within a professional email management system! And there are other aspects that make continuing to use MailStore Server valuable.

Use Your Most Valuable Resource - Time - Easily!
One of the things a company needs when moving to Microsoft Office 365 is time! – a cloud solution doesn't work "out of the box"; the transition requires time and effort. Then, there is the additional time required to set up an email archiving system under Office 365 – a time that any IT manager would prefer to invest in daily tasks. And finally, we believe that companies should not mortgage their new systems with old data, and therefore we always recommend our customers to archive emails rather than migrate them.
You're Already Using a Legally Compliant Archiving System with Your Retention Policies – So Why Change?

No matter what your email system is, MailStore Server offers you these advantages.
The difficulties faced by an internal IT department of a company are numerous and varied, and include not only the growing threat scenario, but also the situation known as shadow IT. Being aware of the need to overcome all these difficulties, it's worth asking whether it makes sense to spend time changing to a fully functional email archiving solution where retention policies and privileges are already defined and implemented; the old saying "never change a working system" immediately comes to mind. And we should not forget the users who are very happy to continue using proven features such as Quick Search or Advanced Search in MailStore Server, or the Outlook Add-In.
Therefore, our recommendation to close this blog post is: If you are planning to move to Microsoft Office 365, stay with MailStore Server, which helps you continue archiving your emails in a legally compliant manner.
