It provides us all the required features for composing efficient mail as well as categorizing mails. Overall: Best mailing application I've come across. Compatible with Windows 10 and Outlook 2016, 2013 (32-/64-Bit) and Outlook 2007. SimpleSYN Business version can run as a Windows service. Sometimes Outlook gets hanged when it has to load several mails, if this gets fixed, it will be more faster to use. SimpleSYN is flexible in its setup with the direction and mode of the synchronization (new, changed and deleted items) set individually for each Outlook folder. We can compose mail just like we edit any document, much easier to compose mail than other competitors. We can add several add-ons (both Microsoft's and our internal organizational),ħ. Other important feature is Reminders (Calendar), it gives notification of an event before 15 mins. We can assign different priorities to the mail and and flag mails also,ĥ. Other useful feature is Focused Inbox and Others Inbox, non-actionable mails can be sent to Others folder such as monitoring mails etc.,ģ. One of the most useful features of Outlook is that we can create different folders in inbox main folder, and create rules for them, it helps us in sorting out mails,Ģ.
