MailStore Server for Office 365

Email is one of the most sensitive business data for compliance, accessibility and retention. MailStore Server will keep an on-premise copy of all the mailboxes, including old and new emails. Pricing starts at just 295 €.



It is just common sense to keep a full copy of all your data in-house, regardless how Office 365 would work in the future. With your own data safe, you can even change to a different provider immediately.

Security & archival

Office 365 only keeps deleted emails for 30 days, while subscribing to cloud archival (E3) costs more than buying MailStore. Get security against accidential deletion and keep all your emails safe in MailStore, without mailbox size or retention limitations.

Company-wide search

Search across all old and new business emails within MailStore in a single interface. No need to pay for employees who already left the company, their archives are stored free of charge.

Proven and reliable

Over 50,000 companies have chosen MailStore Server already, out of which 98,9% would suggest it to new customers. Find out why!

Vade Secure for Office 365

Email is still the primary way of infection in the enterprise. Your business emails are not safe with Microsoft, as the bare minimum for every decent attacker is to get through Office 365's built-in defenses. While 80% of users are unable to tell the difference between a malicious email and a good one, only good external protection can provide efficient email security.

A proven solution, protecting hundreds of millions of mailboxes world-wide.

Targeted attack protection

With advanced spear phishing protection, Vade Secure provides efficient security against targeted attacks and phishing threats. These tricky emails circumvent antivirus and sandboxing and cause huge damage without binaries.

Newsletter, social and shopping folders

Vade Secure classifies newsletters, social and shopping updates in separate folders, so they do not interfere with priority business emails.

Advanced security with artificial intelligence

With time-of-click protection, malicious links are checked even after an email is received. AI helps to go beyond scanning email headers and contents to understand the context and intent, for much better classification.

Fully Office 365 integrated

With a very simple setup that requires no DNS MX record changes, Vade Secure integrates directly into Office 365 using API.
