Sending digitally signed and encrypted email using Outlook is easy. However try doing this using Thunderbird! Office365 support also hesitates to help. Its easy to send digitally signed emails using Thunderbird if one uses Google's GSuite for Enterprise. Would be nice if it could be so with Office365 for Business too. Forget Thunderbird, its not possible using Windows 10 Mail too

Is there anyway that the folders in Sharepoint could be filtered by document name rather than "Last Modified" - Speaking with Office 365 support they said this was functional on Desktop Outlook but not online Office 365 - It would be great if this was possible! It would save time finding the folder that you require! Thanks Chloe

One of the bullet points described here: https://products.office.com/en-us/compare-all-microsoft-office-products?tab=2 states that "web versions of Outlook" are included in Office 365 Business. Unfortunately, upon purchasing, there does not appear to be a web version of Outlook included. A call to support confirms that, contrary to the Microsoft Outlook pricing website, there is no web version of Outlook included in Office 365 Business. Recommendation: revise the 365 Business Pricing Page to reflect that the web version of Outlook is not included. Thank you.

I thought I was getting with a 365Office ProPlus subscription but evidently not. This is what would keep me using Excel but alas it's not available for a Mac

My product, NiftyImages.com offers personalized image and countdown timers that integrate into all current email platforms and we would like to make sure your Connections clients can use our tool as well. Some early access for testing or integration talks would be great!

Freezing flagged emails similar to frozen panes in Excel, will prevent them getting pushed down the list with new emails, requiring searching back down the list to find them and also help the user address them more timely and remove the flag.

This was a very valuable feature that has been deprecated by Microsoft.
