Office365 Outlook for work email change signature how ?

[zillah]

Dear folk


My work domain email is using Office 365 ,,,,I changed my mobile number ,,,,when I



signed to Outlook on the web--> Go to Settings. > View all Outlook settings >





Compose and reply --> Under Email signature, but I can't see any signature.


But when I send an email from my work email to my private email signature is there



Is there any other way to access the signature ? is it disabled by admin ?


Thx
