No. There's a limit to the number of devices a user's license for Office obtained with an O365 subscription can be used on, but no theoretical limit to the number of devices that can have a mailbox opened on them (Not to say that there aren't performance issues with lots of devices accessing the same mailbox, but there is no licensing limitation or technical limitation that prevents such use)

That sounds theoretically correct, however I have never heard of anyone with more than a handful of devices connected to a single mailbox.

Is there a limit of number of devices that can use the same O365 mailbox?

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

A tablet computer is a mobile computer with a touchscreen display, circuitry, and battery in a single device. Tablets come equipped with sensors, including cameras, a microphone, and an accelerometer, and the touchscreen display uses the recognition of finger or stylus gestures replacing the usage of the mouse and keyboard. They usually feature on-screen, pop-up virtual keyboards for typing. Tablets may include physical buttons for basic features such as speaker volume and power, and ports for network communications and battery charging. Tablets are typically larger than smartphones or personal digital assistants.
