Utilisation d’Outlook pour iOS pour la gestion des e-mails et calendriers personnels
Hi there,
I'm Cherrelyn and I'm here to help.
Accidentally deleting an alias can be tricky. Microsoft usually holds deleted aliases for a short time before releasing them, so try adding the alias back to your account as soon as possible. If it won’t let you add it back, it might be locked or taken. In that case, contacting Microsoft support https://support.microsoft.com/ quickly is your best shot to recover it. Act fast aliases don’t stay available for long after deletion.
I hope this will help and If you have any question please feel free to ask.
Warm regards,
Cherrelyn
