Cons
Con Proprietary
Uses proprietary software.
Con Dependant on having an Internet connection
Con Cloud dependent
Does not edit local files, they have to be synced first.
Con Unusable for business in the EU
Cloud applications are mostly incompatible with the EU general data protection regulation.
Con Has only a fraction of Microsoft Office functionality
Office 365 is not a complete replacement for Microsoft Office. The most advanced functionality still can only be found on the desktop.
Con Expensive
$35/user/mo.
Con Can't choose different settings for each mail account
Settings have to applied to all mail accounts.
Con Limited configuration options
Cannot format date as preferred.
Con RAM heavy
Very heavy on RAM usage.
Con Poor integration in any non-GNOME desktop
It is written with GNOME in mind.
Con No configuration messages
Although base functions like bullets, numbered, or pre-formatted text are possible, you can't select or set the font for your messages. Not even serif or sans serif. Which is a bit spartan TBH.
Con Can be wobbly with EWS
Don't be surprised if you have to reboot it a couple of times during a working day, because error messages are piling up (e.g. connection lost, can't sync, can't store appointment, read only). Then again, is this Evolution, or what it connects to? And since such an occasional reboot is dwarfed by the fact that MS365 seems to make full IMAP/ SMTP access (close to) impossible (nice meeting invite, THX, but when is it?), just reboot and get some work done...
Con Only available on Linux
If you have to switch to another platform for whatever reason, you will need to search for a different email client.
