Windows 10: outlook 365 as email default for excel

When sharing an excel file I prefer to share as an email attachment. However, Outlook 365 is not listed as an option. Is there a way to have outlook 365 as a default email app?

Office 365 Outlook email accounts

The reason I am asking these questions are that two individuals are buying two new laptops and would like to share one Microsoft Office 365 Personal.
A has a subscription to Microsoft Office 365 Personal already and wants to share the same account with B.
I have installed Microsoft Office 365 Personal in a second pc B and when launching Outlook all my email accounts from A were loaded. So, I cannot figure out how to install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded.
This raises more questions for me.

1. So this
   • User A installs and activates O365 on User B's laptop
   • User B adds his / her email accounts to Outlook
   would not apply to Microsoft Office 365 Personal as it breaches the licence agreement?
2. Am I correct?
3. If it does apply how can I install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded, and I can only add B email account on the second pc?
4. Would B be able to access A OneDrive?
5. Or would B have a separate 1TB free space in One drive, or only the free 5GB or none at all?
6. And most importantly is this even legal or in breach of contract as Microsoft Office 365 Personal is for one user only?

 

Office 365 Outlook email accounts

O365 Personal cannot be shared. It can be installed on unlimited number of devices, but it must be activated with the same subscriber Microsoft account on each device.

Extract from Office 365 subscriptions - On how many devices can Office be installed:

However, the activation Microsoft account email does not have to be added to Outlook. A fully valid and functional example:

• User A subscribes to O365 Personal
• User A installs and activates O365 on his / her laptop
• User A adds his / her email accounts to Outlook
• User A installs and activates O365 on User B's laptop
• User B adds his / her email accounts to Outlook

The point is, that the O365 Personal subscriber email is required to activate Office on each device, but it don't have to be added to Outlook. In above example, both User A and User B add only their own email accounts to Outlook, and cannot see each other's accounts and emails.

Exactly.

 

Outlook 365 - Can't select From email account or set default signature

Greetings,

Specs:
Win 10 Pro x64 - Version 1909 - Build 18363.720
Office 365 / Outlook - Version 2003 - Build 12624.20176, Monthly Channel (Targeted)

Everything was running fine with my O365 Business Premium and its Outlook program on my Win10 PC until this morning when I launched it and encountered two issues.

Issue #1
'From:' email address blank - When creating a new email, the 'From:' email address field is blank, instead of showing my default email account...and I cannot type into the field. And the 'From:' button no longer displays a drop-down of my email accounts to choose from. The button is dead and does nothing now.

• I have several different email accounts setup in Outlook, including my businesses domained email address, some Outlook.com addresses, and some addresses from my ISP. All used to be listed in the From drop-down, until this morning.

Issue #2
Default Email Signatures - While tinkering around trying to solve #1, I noticed in my Outlook options for 'Signatures and Stationary' that all three drop-down boxes for 'Choose default signature' are greyed out and not active, although all my email signatures are listed in the box to the left and can still be edited. In other words, I can no longer choose my default email address. Now, all new emails I start default to my business domained email address.

• Oddly, if within a new email, I select Signature from the Include section of the ribbon bar, I can change the signature to one of my other account signatures.
• I created a new email signature to test if the three boxes would come back to life and they didn't.

I've also done the following:
Run both the Quick and Full repairs for Office365 - Didn't resolve the issues
Restarted O365 in Safe Mode - Issues were present in safe mode

I don't know if the two issues are related, but everything was fine this morning when I closed Outlook. The only thing I did after that was the latest March 12 Win 10 update, KB4551762, then rebooted the PC. A couple hours later, I re-launched Outlook to get to work...and those issues appeared.

I've looked everywhere for a solution, including the forums here, and came up with nothing. I'd really appreciate anyone who knows how to resolve these issues.

Thank you
