Send link doesn't find a person in my organisation

[matthiew-RAA]

One of my colleages is trying to share a file with our boss, but OneDrive can't find him.

• It's an Excel spreadsheet.
• She's tried sharing from Excel, and from Explorer. Both failed to find him.
• She can find other people and send the link to them.
• I tried the same steps on my computer and I am able to send links to him.

Does anybody know how to fix this?

@matthiew-RAA Your company helpdesk is the first place to go as they manage your Microsoft 365 environment (including OneDrive for Business).

I figured it out. His account was hidden from the Global Address List. It doesn't make sense that this setting doesn't apply to all users, but that is a separate issue.
